= 4.3.4 =
* New feature: You can now give Gutenberg blocks a CSS class `relevanssi_noindex` to exclude them from being indexed. Relevanssi will not index Gutenberg blocks that have the class.
* New feature: Relevanssi automatically skips some custom fields from common plugins that only contain unnecessary metadata.
* New feature: The search results breakdown is added to the post objects and can be found in $post->relevanssi_hits. The data also includes new fields and the breakdown from the excerpt settings page can now show author, excerpt, custom field and MySQL column hits.
* New feature: Relevanssi can now index Ninja Tables table content. This is something of an experimental feature right now, feedback is welcome.
* New feature: New filter hook `relevanssi_indexing_query` filters the indexing query and is mostly interesting for debugging reasons.
* Minor fix: Deleted and trashed comment contents were not deindexed when the comment was removed. That has been corrected now.
* Minor fix: Phrase matching is now applied to attachments as well, including the attachments indexed for parent post.
* Minor fix: Phrase matching only looks at custom fields that are indexed by Relevanssi.
* Minor fix: Exact match bonus now uses the original query without synonyms added for the exact match check.
* Minor fix: Paid Membership Pro filtering is only applied to published posts to prevent drafts from showing up in the search results.

= 4.3.3 =
* New feature: New filter hook `relevanssi_indexing_adjust` can be used to stop Relevanssi from adjusting the number of posts indexed at once during the indexing.
* New feature: New filter hook `relevanssi_acf_field_value` filters ACF field values before they are indexed.
* New feature: New filter hook `relevanssi_disabled_shortcodes` filters the array containing shortcodes that are disabled when indexing.
* Removed feature: The `relevanssi_indexing_limit` option wasn't really used anymore, so it has been removed.
* Changed behaviour: Indexing exclusions from Yoast SEO and SEOPress are applied in a different way in the indexing, making for a smoother indexing process.
* Changed behaviour: WP Table Reloaded support has been removed; you really shouldn't be using WP Table Reloaded anymore.
* Minor fix: Relevanssi won't choke on ACF fields with array or object values anymore.
* Minor fix: Relevanssi uninstall process left couple of Relevanssi options in the database.
* Minor fix: WPML language filter didn't work when `fields` was set to `ids` or `id=>parent`.

= 4.3.2 =
* New feature: SEOPress support, posts marked "noindex" in SEOPress are no longer indexed by Relevanssi by default.
* Changed behaviour: Membership plugin compatibility is removed from `relevanssi_default_post_ok` function and has been moved to individual compatibility functions for each supported membership plugin. This makes it much easier to for example disable the membership plugin features if required.
* Minor fix: The `searchform` shortcode now works better with different kinds of search forms.
* Minor fix: Yoast SEO compatibility won't block indexing of posts with explicitly allowed indexing.
* Minor fix: The `relevanssi_the_tags()` function printed out plain text, not HTML code like it should. The function now also accepts the post ID as a parameter.
* Minor fix: Excerpt creation and highlighting have been improved a little.

= 4.3.1.1 =
* Remove notice about undefined index.

= 4.3.1 =
* Adding a missing file.

= 4.3.0 =
* New feature: Multi-phrase searches now respect AND and OR operators. If multiple phrases are included in an OR search, any posts with at least one phrase will be included. In AND search, all phrases must be included.
* New feature: Admin search has been improved: there's a post type dropdown and the search is triggered when you press enter. The debug information has a `div` tag around it with the id `debugging`, so you can hide them with CSS if you want to. The numbering of results also makes more sense.
* New feature: The date parameters (`year`, `monthnum`, `w`, `day`, `hour`, `minute`, `second`, `m`) are now supported.
* New feature: New filter hook `relevanssi_indexing_limit` filters the default number of posts to index (10). If you have issues with indexing timing out, you can try adjusting this to a smaller number like 5 or 1.
* New feature: Support for Paid Membership Pro added.
* New feature: WordPress SEO support, posts marked "noindex" in WordPress SEO are no longer indexed by Relevanssi by default.
* Removed feature: qTranslate is no longer supported.
* Major fix: Tax query searching had some bugs in it, manifesting especially into Polylang not limiting the languages correctly. Some problems with the test suites were found and fixed, and similar problems won't happen again.
* Minor fix: Admin search only shows editing options to users with enough capabilities to use them.
* Minor fix: Phrase searching now uses filterable post statuses instead of a hard-coded set of post statuses.
* Minor fix: The plugin action links were missing on the Plugins page list, they're back now.
* Minor fix: Search terms with slashes won't cause errors anymore.
* Minor fix: Relevanssi admin pages have been examined for accessibility and form labels have been improved in many places.
* Deprecated: `relevanssi_get_term_taxonomy()` function is deprecated and will be removed at some point in the future.

= 4.2.0 =
* New feature: The search form shortcode has a new parameter `dropdown` which can be used to add a category dropdown, like this: `[searchform dropdown="category"]`.
* New feature: Relevanssi can now use the contents of the PDF files indexed with WP File Download.
* New filter: `relevanssi_indexing_tokens` can be used to filter the tokens (individual words) before they are indexed.
* Removed filter: `relevanssi_default_meta_query_relation` did not have any effect anymore.
* Changed behaviour: The default taxonomy relation was set to AND in 4.1.4, but wasn't properly applied before. Now it is really switched.
* Changed behaviour: New post types have been added to list of forbidden post types Relevanssi won't show as indexing options (ACF, TablePress and WooCommerce).
* Major fix: Tax query processing has been completely refactored, eliminating all sorts of bugs, especially with various edge cases.
* Major fix: Gutenberg block indexing only worked with the Gutenberg plugin enabled. It now works with WP 5.0 built-in Gutenberg as well. If you use Gutenberg blocks, reindex to get all the block content in the index.
* Major fix: Excerpt-building and highlighting did not respect the "Keyword matching" setting. They do now, and the excerpts should be better now.
* Major fix: AND searches needed queries that could get too long for the database to handle. This has been fixed and optimized.
* Major fix: Taxonomy term subquery relations didn't work; now they are applied.
* Minor fix: iOS uses curly quotes by default, and that didn't work as a phrase operator. Now phrase operator works with curly quotes and straight quotes.
* Minor fix: The Did you mean broke with search terms longer than 255 characters.
* Minor fix: Phrases with numbers and one word like "team 17" didn't work, because numbers weren't counted as words.

= 4.1.4 =
* `EXISTS` and `NOT EXISTS` didn’t work for taxonomy terms in searches.
* WPML post type handling has been improved. If post type allows fallback for default language, Relevanssi will support that.
* Relevanssi now reminds you to set up automatic trimming for the logs. It’s a really good idea, otherwise the logs will become bloated, which will hurt search performance.
* The Groups posts filter is only applied to public posts to avoid drafts being shown to people who shouldn’t see them.
* The `posts_per_page` query variable didn’t work; it’s now added to the introduced query variables so that it works.
* Relevanssi won’t log empty queries anymore.
* The default tax query relation was switched from `OR` to `AND` to match the WP_Query default behaviour.
* When used with WP 5.1, Relevanssi will now use `wp_insert_site` instead of the now-deprecated `wpmu_new_blog`.
* Multisite blog creation is handled better in WP 5.1+.
* Relevanssi now supports Restrict Content Pro permissions.

= 4.1.3 =
* Improvements to meta key sorting.

* Members plugin compatibility has been improved: it's only used if the 'content permissions' feature has been enabled.
* The excerpt settings page was a bit buggy.
* Slimstat analytics is now added to the blocked shortcodes list.
* New filter: `relevanssi_search_form` works exactly like `get_search_form`, but only applies to the Relevanssi shortcode search forms.
* New JetPack taxonomies and post types have been added to the block list so they won't appear in Relevanssi settings.

= 4.1.2 =
* Choosing "CSS Style" for highlighting was not possible. That is now fixed.
* Gutenberg reusable block indexing was fatally broken with the latest Gutenberg version. That has been updated.
* Relevanssi now by default respects the WooCommerce "exclude from search" setting.
* `post__not_in` still didn't work properly, it does now.
* New filter: `relevanssi_comparison_order` can be used to define the sorting order when sorting the results by post type.
* "Did you mean" process included a very slow query. It is now cached, leading in some cases to massive performance improvements (we're talking about several seconds here).
* Highlights inside `code` and similar blocks are handled better now.

= 4.1.1.2 =
* Fixes the broken User searches page.

= 4.1.1.1 =
* Adding the missing Gutenberg compatibility file.

= 4.1.1 =
* Relevanssi can now index Gutenberg reusable blocks. (This functionality broke once already before release, so that can happen, since Gutenberg is still in very active development.)
* The `post__in` and `post__not_in` parameters didn't work, and are now fixed. `post_parent__in` and `post_parent__not_in` are also improved.
* You can use named meta queries for sorting posts. Meta query sorting is improved in other ways as well.
* Log export didn't work properly.
* Adding stopwords from the common word list has been fixed.
* The `relevanssi_get_words_having` filter hook is now also applied to the free version Did you mean queries.
* New filters: `relevanssi_1day` and `relevanssi_7days` can be used to adjust the number of days for log displays, so instead of 1, 7 and 30 days you can have anything you want.

= 4.1.0.1 =
* Actually working admin search.

= 4.1 =
* New feature: You can now export the search log as a CSV file.
* New feature: Admin Search page allows you to perform searches in WP admin using Relevanssi.
* New filter: `relevanssi_admin_search_capability` can be used to adjust who sees the admin search page.
* New filter: `relevanssi_entities_inside_pre` and `relevanssi_entities_inside_code` adjust how HTML entities are handled inside `pre` and `code` tags.
* Numeric meta values (`meta_value_num`) are now sorted as numbers and not strings.
* Pinned posts have `$post->relevanssi_pinned` set to 1 for debugging purposes, but you can also use this for styling the posts in the search results templates.
* The Did you mean feature has been toned down a bit, to make the suggestions slightly less weird in some cases.
* Post parent parameters now accept 0 as a value, making it easier to search for children of any post or posts without a parent.
* Polylang compatibility has been improved.
* Phrases with apostrophes inside work better.
* The `relevanssi_excerpt` filter hook got a second parameter that holds the post ID.
* Custom field sorting actually works now.
* WP Search Suggest compatibility added.

= 4.0.11 =
* Home page links were getting the highlight parameter even though they shouldn't. This has been fixed.
* Added support for WP JV Post Reading Groups.
* Improved handling of HTML entities.
* Events Made Easy Calendar shortcodes are now removed when building excerpts.
* `set_time_limit()` was removed from the indexing; it's no longer necessary, and it can break the indexing on sites that don't allow the use of the function.
* `relevanssi_post_title_before_tokenize` filter was moved a bit so that it's the last thing that runs before tokenizing.
* Disabled shortcodes are handled better in the indexing: the shortcode names won't be indexed anymore like they were before.
* Made sure there won't be a warning for non-numeric values when searching.
* New filter: `relevanssi_clean_excerpt` lets you remove unwanted highlights from excerpts.
* Highlighting works better with `pre` and `code` tags.
* New filter: `relevanssi_comment_author_to_index` lets you filter comment author names before indexing.
* `relevanssi_comment_content_to_index` doesn't include the comment author name anymore.

= 4.0.10.1 =
* The privacy features caused an error notice with certain Relevanssi configurations, and the plugin required WP 4.9.6.

= 4.0.10 =
* Privacy: If you log search queries, Relevanssi will suggest some additional content to your privacy policy page.
* Privacy: Relevanssi now supports the new Privacy Policy and Personal Data tools in WordPress 4.9.6.
* Saving synonyms with quotes worked, but the synonyms showed up wrong.
* Relevanssi could in some situations override navigation menu links with links to the user profiles or taxonomy terms found in the search. This update fixes that behaviour.
* Random order works again; using orderby `rand` didn't work properly. The `rand(seed)` format is also supported now.
* Fixed quotes and apostrophes in Did you mean suggestions.

= 4.0.9 =
* Fixes broken tag and category indexing and searching. If you use tags and categories, rebuild the index after updating.
* Phrases were not highlighted correctly on documents. This is now fixed.
* Shortcode fix: 'wp_show_posts' shouldn't cause problems anymore.
* New filter: `relevanssi_indexing_restriction` allows filtering posts before indexing.
* New WooCommerce product visibility filtering tool makes WooCommerce product indexing faster.
* MemberPress post controls were loose and showed drafts to searchers. That is now fixed.
* Highlighting was too loose, even if matching was set to whole words.
* Highlighting now works better in cases where there's a hyphen or an apostrophe inside a word.

= 4.0.8 =
* Fixed cases where Relevanssi added an ellipsis even if the excerpt was from the start of the post.
* Highlighting now works with numeric search strings.
* Improved highlighting for accented words. Thanks to Paul Ryan.
* A surplus comma at the end of post exclusion setting won't break the search anymore.
* Fixed instructions for adjusting the throttle limit.

= 4.0.7 =
* Recent post bonus is now applied to searches.
* Exact term setting can now be disabled.
* Users of Members plugin would have drafts appear in search results. This is now fixed.

= 4.0.6 =
* Indexing bugs squashed.
* Missing tag and category weight settings returned.
* Fusion builder shortcodes are removed from excerpts.
* MemberPress post control was backwards.
* User searches page reset buttons fixed.

* Gravity Forms shortcode is now disabled in Relevanssi indexing.
* New filter: `relevanssi_excerpt_query` filters the search query before building excerpts.
* HTML tags are stripped from post excerpts when using the excerpt to build Relevanssi excerpts.
* Fixed filter: `relevanssi_custom_field_value` didn't have the correct post ID parameter.
* `relevanssi_get_permalink` doesn't add the `highlight` parameter to URLs outside search results pages anymore, and won't add the parameter to front page links either.
* Relevanssi used `sanitize_hex_color`, which isn't actually reliably available.
* Did you mean suggestions have been improved.
* Single-word phrases are not allowed anymore, as they do no good. They are silently converted to non-phrases now.

= 4.0.3 =
* Relevanssi didn't index all posts with one go. It does now.
* © and ® symbols caused problems in indexing; they are now included in the default punctuation removal.
* In some cases excerpt-building could take ages because of autoembed link discovery. Relevanssi now blocks the autoembed procedure in link-building.
* New filter: `relevanssi_custom_field_value` is used to filter custom field values both before indexing and before excerpt-building. Parameters include the field name and the post ID.
* Updated filter: `relevanssi_index_custom_fields` now gets a second parameter that contains the post ID.

= 4.0.2 =
* Removed couple of error notices in the code.
* Improved the support for page builders.
* Improvements to the Polylang setting.

= 4.0.1 =
* The plugin can now be uninstalled.

= 4.0 =
* Legacy code has been removed. If you have a version older than 3.6, update first to 3.6.2.2 to guarantee smooth upgrade process.
* Improved indexing: no more clicking "Continue indexing" again and again!
* Settings pages have been completely rewritten.
* There's documentation in the WordPress contextual help: just click Help on the top right corner.
* Better Polylang support. A new option to remove the Polylang language filter.
* Logs can be automatically trimmed. Old log entries are removed to save space.
* Finally a setting to adjust content weight!
* Excerpts can use the custom field content.
* Highlighting in documents is changed: it now requires a `highlight` query parameter. This helps getting pass caching and makes the highlighting more reliable. To get the query parameter active, use `relevanssi_get_permalink()` to print out the permalinks on the search results templates.
* Relevanssi added synonyms to highlighting even if synonyms were not used for searching. In some cases, synonyms were added twice.
* The User Searches page got a makeover, too.
* Relevanssi is automatically disabled in REST API searches.
* Groups and Simple Membership support has been improved.
* Sorting search results is now up to 300 times faster than before.
* Lots of improvements all over the place.
* New filter: `relevanssi_excerpt_custom_field_content` lets you modify custom field content that is used for excerpts.
* New filter: `relevanssi_punctuation_filter` allows for easy modification of punctuation handling.
* New filter: `relevanssi_default_punctuation_replacement` changes the default way to handle the rest of the punctuation.

* New filter: `relevanssi_page_builder_shortcodes` lets you control which page builder shortcodes Relevanssi removes before building the excerpts.
* New filter: `relevanssi_optimize_excerpts` makes excerpt-building faster, if you make the filter return `true`.

= 3.6.2.2 =
* A bug in post sorting broke string sorting (mostly post title sorting).

= 3.6.2.1 =
* A bug was left in the post ordering code. That bug is now squashed.

= 3.6.2 =
* Simple Membership plugin is now supported automatically to restrict access to posts.
* Relevanssi can now handle orderby parameter in array format.
* Relevanssi now blocks Easy Digital Downloads shortcodes when indexing to improve compatibility with EDD.

* New action: `relevanssi_update_options` lets you adjust Relevanssi options immediately after the defaults are set.
* Remove notices about duplicated database columns when installing the plugin.

= 3.6.1 =
* SECURITY: This version fixes a SQL injection vulnerability, where a site admin could theoretically inject SQL code into Relevanssi search queries. Doing this required access to Relevanssi settings page and in my tests, I couldn't do any damage, just break the Relevanssi search, but in any case, this vulnerability is now fixed.
* Search and Filter shortcode is added to the blacklist.
* Groups plugin is now supported automatically to restrict access to posts.
* The filter `relevanssi_index_custom_fields` now works even if the custom field setting is empty.
* The filter `relevanssi_post_to_index` now has a second parameter. For posts, it simply repeats the post object, but for taxonomy terms, it has the term object.

= 3.6.0 =
* Changed a bit how Relevanssi attaches itself to queries. Instead of the global $wp_query, Relevanssi now uses the query passed as the parameter to `the_posts` filter hook. This should improve compatibility in some cases, but may cause problems in some fringe cases. If you're doing something unusual with Relevanssi, try this out before deploying to public use.
* Some meta queries caused major problems with the Relevanssi weighting algorithm. This has now been fixed.
* Error notices caused by trying to use a non-existing taxonomy term have been removed.

= 3.5.12 =
* Post type exclusion didn't work as expected.
* Relevanssi couldn't handle nested tax queries (such as those generated by WooCommerce product visibility filtering) properly.

= 3.5.11.1 =
* New filter: `relevanssi_allow_one_letter_highlights` lets you allow one-letter highlights. Just make the filter function return `true`.
* New filter: `relevanssi_block_one_letter_searches` by default blocks one-letter searches. If you want to enable them, add a filter function that always returns `false`.
* Fixed an undefined variable notice.

= 3.5.11 =
* Synonym indexing failed if synonyms contained a forward slash.
* Highlighting HTML tags has been improved further.
* New filter: `relevanssi_tag_before_tokenize` allows you to access tag content before indexing.
* Relevanssi now actively blocks one-letter search terms, as they are generally pointless and can cause "out of memory" issues. One-letter search terms are no longer highlighted, either. These are usually caused by cases like "word's" being interpreted as "word s".
* New filter: `relevanssi_disable_shortcodes_excerpt` lets you add more shortcodes to be disabled before excerpts are built.

= 3.5.10 =
* Some users got a fatal parse error. That shouldn't happen anymore.
* FacetWP users ran into trouble, as `relevanssi_do_query()` started to explicitly expect a WP_Query object in version 1.15.0. That expectation is removed; it's still highly recommended for future compatibility that you use WP_Query objects.
* Small bug fix: `get_current_screen()` is now only used when it's available to avoid occasional fatal errors.
* Error messages from `DOING_AJAX` being undefined should be removed.

= 3.5.9.1 =
* WP.org plugin repo didn't like 3.5.9 for some reason, hoping to have better luck with this.

= 3.5.9 =
* Improved the way highlighting handles HTML tags, especially when highlighting on post pages.
* The throttle limit setting was removed from the settings page for causing trouble. If you need to change it, update `relevanssi_throttle_limit` option directly.
* Relevanssi didn't support tax_queries with `field` set to `name`. That works now.
* Much faster way of showing the 25 most common words in the index. If you've disabled this feature because it was so slow, try enabling it - you might be surprised!

= 3.5.8 =
* Did you mean function had a XSS vulnerability, which is now removed.
* Minimum word length wasn't applied to titles in indexing. It is now fixed. If you think this is a problem, rebuild the index.
* TablePress compatibility has been improved.
* Meta query handling has been improved, thanks to Maxime Culea.
* Improved WP_Query parameter support: setting query variable `sentence` to 1 forces phrase search.
* Improved ACF compatibility.

= 3.5.7.1 =
* Small fix for a bug that broke the settings page.

= 3.5.7 =
* An improved version of the sorting function will not throw notices when Intuitive Custom Post Order plugin is used.
* New filter: `relevanssi_missing_sort_key` can be used to adjust the result sorting when using keys that are not present in all posts (eg. menu_order).
* Czech translation and stopwords, thanks to Michael Kucera.
* Relevanssi broke the WP admin menu search when admin searches were enabled.
* Relevanssi broke the admin page search under WP 4.7. Relevanssi is now disabled in admin page searches.
* The way accented characters are handled in highlighting is improved. A new filter, `relevanssi_accents_replacement_arrays`, can be used to adjust the accent replacement.

= 3.5.6.1 =
* Fix for a fatal bug in 3.5.6.

= 3.5.6 =
* Relevanssi admin page had a vulnerability that allowed SQL injection attacks. That is now fixed.
* Relevanssi didn't like to highlight search terms that are followed by a ?, an ! or an apostrophe.
* New filter: `relevanssi_ok_to_log` lets you control whether search queries are logged or not.

= 3.5.5 =
* 500 errors caused by arrays in custom fields should be gone now.
* Improvements to the ACF "select" field support.
* Relevanssi will not break when frontend plugins insert posts.
* `relevanssi_match` filter has a new parameter, which contains the search term.
* Polylang support has been improved.
* WPML and Polylang filters work when "fields" is set to "ids".
* New filter: `relevanssi_log_get_user` gets passed the user object before Relevanssi decides if the query should be logged or not.

= 3.5.4 =
* Relevanssi had a bug that lead to inflated relevancy scores for posts.
* Relevanssi can now index the human-readable labels of ACF "select" fields. (Thanks to Raphaël Droz.)
* New filter: `relevanssi_30days` can be used to adjust the 30 day logs to a different number of days.
* Adding stopwords that contain apostrophes didn't work.
* Ensured PHP7 and WP 4.6 compatibility.
* Fixed a small glitch that could happen if a highlighted term is next to a starting square bracket.

= 3.5.3 =
* New filter `relevanssi_user_searches_limit` to adjust the number of user searches shown in the logs.
* Old data check is only done on Relevanssi settings page, not on all admin pages. That should improve admin performance.
* Fixed a fatal error when searching includes private posts.
* New filter: `relevanssi_remote_addr` can be used to modify the IP address logged to Relevanssi logs.
* Blocked CFDB and WooCommerce shortcodes that are causing problems with Relevanssi.

= 3.5.2 =
* Added correct support for `term_taxonomy_id` in the `fields` parameter in tax_queries.

= 3.5.1 =
* Fixed an error in the Did you mean function.
* Fixed an error if the search term was not found in content.
* Fixed an error when building excerpts from posts shorter than the excerpt length.
* Blocked the `[starpro]` shortcode that was causing problems with Relevanssi.
* New filter: `relevanssi_remove_stopwords_in_titles` allows you to include stopwords in titles.
* Added support for `term_tax_id` in the `fields` parameter in tax_queries.
* Excerpt-building failed if multibyte string operations were missing. It should work now.

= 3.5 =
* Tokenizer was using `strlen()` and not `mb_strlen()`, so word lengths were not calculated properly. If your site uses non-ASCII alphabet, rebuilding the index is a good idea.
* Small improvement to WPML multilanguage filtering.
* `relevanssi_the_title()` got a new parameter: if you don't want to echo the title, you can use it like `relevanssi_the_title(false)` to make it return the title.
* Relevanssi had `the_title` filter hook calls that were missing the second parameter; that's now fixed.
* The excerpt-building algorithm is completely rewritten based on work by Ben Boyter (http://www.boyter.org/).
* The `[watupro]` shortcode didn't work with Relevanssi, so Relevanssi will now bypass it.
* The plugin i18n features have been improved slightly.
* New filter: `relevanssi_didyoumean_suggestion` lets you modify the Did you mean? suggestion before it's displayed.
* `relevanssi_didyoumean()` has a new parameter: you can now choose whether the result is echoed out (the default value) or just returned.
* In the search results breakdown, you can now use %categories% and %taxonomies% to show the number of matches in categories and taxonomies other than tags and cats, respectively.
* Relevanssi supports `fields` parameter (both `ids` and `id=>parent`) to return only post IDs or post IDs and post parents.

= 3.4.2 =
* Empty lines on synonym settings caused problems. Fixed that.
* In WordPress 4.2 installations, emoji in will be handled better. Emoji in posts may cause problems with WordPress versions below 4.2, so please update!

= 3.4.1 =
* Removed a notice about an undefined variable.

= 3.4 =
* New filter: `relevanssi_valid_admin_status` can be used to adjust post statuses that Relevanssi will handle.
* If Relevanssi creates an empty excerpt for a post and there's a user-set excerpt for the post, that excerpt is used.
* No ellipsis is added to the post excerpt, if the post excerpt shows the whole post.
* The `relevanssi_post_title_before_tokenize` filter now has a second parameter that contains the post object.
* New filter: `relevanssi_display_common_words` can be used to disable the "25 most common words" listing on the settings page, if it's too heavy to load.
* Relevanssi was sanitizing taxonomy titles too aggressively. That is now toned down a bit.
* Relevanssi now supports `post_parent`, `post_parent__in` and `post_parent__not_in`, though you have to set them in `relevanssi_modify_wp_query` filter for them to work.
* Meta query support should now be perfect; there were some limitations with complicated meta queries before.

= 3.3.8 =
* Fixed a bug that caused the results to change depending of the order of words in a multi-word search query.
* Added `product_categories` and `recent_products` from WooCommerce to the list of blocked shortcodes.
* There are improvements in excerpt-building and highlighting, especially when fuzzy search is enabled.
* Fixed a possible (if quite unlikely) XSS vulnerability.
* Improved search performance (thanks to MikeNGarrett).
* Sometimes highlights in documents make the document content disappear. I don't know why, but I've added a fix that should make the content visible (without the highlights) if a problem appears.

= 3.3.7.1 =
* Fixed bbPress compatibility.

= 3.3.7 =
* Fixed bbPress compatibility.

= 3.3.6 =
* Relevanssi handles taxonomy terms in search better. The change requires a reindexing.
* Fix in indexing: Relevanssi will now bypass the global $post when indexing. This should help with problems with the Cookie Law Info plugin, for example.
* Tax query relation setting didn't work properly. It is now fixed.
* Word-based excerpt building sometimes created too short excerpts. That is now fixed.
* Synonyms are now highlighted.
* Phrase matching had issues where searching for a too common phrase crashed the search. That has been fixed.

= 3.3.4 =
* Couple of bug fixes.

= 3.3.3 =
* OR fallback had problems.

* Polylang and WPML support was adjusted to perform better in edge cases.
* Indexing is faster, thanks to some improved code from Tom Novelli.

* If Relevanssi Premium is installed, deleting Relevanssi will not remove the databases and the options.

= 3.1.7 =
* New filter: `relevanssi_comment_content_to_index` lets you modify comment content before it's indexed by Relevanssi (to index comment meta, for example).

* Highlighting was broken, and should work much better now.

= 3.1.5 =

* Ordering search results by title or date in admin search works now.
* Modified the way the highlights work; now highlighting words with apostrophes should produce more meaningful results.
* Highlighting should not highlight anything between & and ; or in <style> or <script> tags, thus solving some of the problems related to highlights. Reports of how well this works are welcome.
* On-post highlighting now only highlights content in the loop, so menu texts and other off-the-loop stuff should not get highlights anymore.
* New action hook: `relevanssi_pre_indexing_query` can be used to "SET OPTION SQL_BIG_SELECTS=1" if needed.
* Major indexing problems caused by shortcodes changing the post ID during the indexing of posts are now fixed.
* Relevanssi was being called twice when a post was saved, on `save_post` and `wp_insert_post`. I removed the hook on `save_post`.

* Support for WP Table Reloaded and TablePress. Tables created with these plugins will now be expanded and the content indexed by Relevanssi.
* New filter: `relevanssi_index_comments_exclude` can be used to exclude comments from indexing. The filter gets the post ID as a parameter, so you can prevent comments of particular posts being indexed, yet index those posts.
* Relevanssi now adds spaces between tags when creating excerpts to make neater excerpts from tables and other similar situations.
* Relevanssi now indexes unattached attachments, if you choose to index attachments.
* Fixed the problems with Twenty Ten and Twenty Eleven themes better.

* Searching in subcategories worked sometimes, but not always. Thanks to Faebu.
* The "Limit searches" option didn't work too well in the case of strong weightings, as it didn't take note of any weights. Now it works better.
* Added a note about disabling custom excerpts when they are not needed - they can slow down the search quite a bit.

* Fixed filter: `relevanssi_pre_excerpt_content` wasn't working properly.
* Relevanssi now supports tax_query, for most part. You can query multiple taxonomies, use relation AND and OR, use operators AND, IN and NOT IN and choose include_children (which defaults to true). Old `taxonomy` and `term` still work, but I recommend using tax_query for the level of control it offers.
* Relevanssi now works better with category restrictions. The extra `cats` query variable is no longer necessary, Relevanssi can now read multiple categories from `cat`. You can also use `category__and`, `category__in` and `category__not_in`.
* Same goes with tags: `tags` is now longer necessary. Relevanssi has full support for `tag`, `tag_id`, `tag__and`, `tag__in`, `tag__not_in`, `tag_slug__and`, `tag_slug__in` and `tag_slug__not_in`. For `tag`, both `term1+term2` and `term1,term2` is supported.
* Relevanssi now supports `author_name` and negative values for `author`.
* Relevanssi now supports `offset` query variable.
* Relevanssi now supports meta_query. You can use all comparisons (also EXISTS and NOT EXISTS, even if you don't have WP 3.5). You can also use the older `meta_key` and `meta_value` query variables, including all the comparisons. I have not tested all possible meta_query constructions, so bug reports of things that don't work as expected are welcome.
* New index on the database makes some database operations faster.
* Removed a bug that prevents one-character words from being indexed in titles, despite the minimum word length setting.
* Removed a warning when searching for nothing.
* Fixes a warning about $wpdb->prepare() caused by a change in WordPress 3.5.

* Suppressed notices on one mb_strpos() call.
* Added a search variable "by_date" to filter search results, see FAQ for details.

* Fixed a serious bug related to taxonomy term searches that could cause strange search results. Thanks to Charles St-Pierre for finding and killing the bug.
* Spanish stopwords are now included (thanks to Miguel Mariano).

= 2.3.1 =
* I fixed the highlighting logic a bit, the highlighting didn't work properly before.

= 2.3 =
* New highlighting option: HTML5 mark tag. Thanks to Jeff Byrnes.
* Relevanssi can now highlight search term hits in the posts user views from search. Highlighting for search term hits from external searches will be added later.

* Removed search result highlighting from admin search, where it wasn't very useful.

= 2.2 =
* Relevanssi used to index navigation menu items. It won't, anymore.
* Translation and stopwords in Brazilian Portuguese added, thanks to Pedro Padron.

= 2.1.9 =
* No changes, I'm just trying to resurrect the broken Relevanssi plugin page.

= 2.1.8 =
* Including the popular microtime_float function caused conflicts with several other plugins (whose authors are just as sloppy as I am!). Fixed that.

= 2.1.7 =
* The index categories option wasn't saved properly. Now it is.
* Fixed the %terms% breakdown option to show correct counts and added %total% to show total hit count.
* Phrases are now matched also in post titles and category titles (before they were only matched against post content).
* Post excerpts can now be indexed and searched. I would appreciate feedback from people who use this feature: do you use the excerpts in search results? If you use custom snippets created by Relevanssi, what you want them to display?
* Set the constant TIMER to true to enable timing of the search process for debugging reasons.

= 2.1.6 =

* When doing a phrase search, highlighting will only highlight phrase hits.

= 2.1.3 =
* OR operator makes a comeback! The default operator is now an option, and if you choose AND and search gets no results, an OR search is also run.
* You can now give a list of user ids - any searches by those users will not be logged. List your admin user id, so your test searches won't clutter the log.

= 2.1.2 =
* Removing punctuation didn't work properly, making phrase search impossible. I'd thought I'd fix it, but for some reason I made a mistake and the fix didn't appear in the released versions.
* Search has now an implicit AND operator, which means that every search term must appear in all result documents. Please let me know if you'd prefer an implicit OR operator, like Relevanssi had before.
* Relevanssi options page now shows the amount of indexed documents, making troubleshooting indexing easier.

= 2.1.1 =
* "Did you mean" suggestions now work in blogs that are not in root directory.

= 2.0.1 =
* Exclude posts/pages option wasn't saved on the options page. It works now.

* Comment authors are now included in the index, if comments are indexed.
* Search results can be sorted by any $post field and in any order, in addition of sorting them by relevancy.
* Private posts are indexed and displayed to the users capable of seeing them. This uses Role-Scoper plugin, if it's available, otherwise it goes by WordPress capabilities.
* Searches can be restricted with a taxonomy term (see FAQ for details).

= 1.9 =
* Excerpts are now better and will contain more search terms and not just the first hit.
* Fixed an error relating to shortcodes in excerpts.
* If comments are indexed, custom excerpts will show text from comments as well as post content.
* Custom post type posts are now indexed as they are edited. That didn't work before.

* Custom taxonomies can also be indexed in addition to standard post tags. Default behaviour is to index nothing. If somebody knows a way to list all custom taxonomies, that information would be appreciated.

= 1.7.3 =
* Small bug fix: code that created database indexes was broken. Say "ALTER TABLE `wp_relevanssi` ADD INDEX (doc)" and "ALTER TABLE `wp_relevanssi` ADD INDEX (term)" to your MySQL db to fix this for an existing installation.

= 1.7.2 =
* Small bug fix: public posts that are changed to private are now removed from index (password protected posts remain in index).
* An Italian translation is now included (thanks to Alessandro Fiorotto).

= 1.7.1 =
* Small fix: the hidden variable cat now accepts negative category and tag ids. Negative categories and tags are excluded in search. Mixing inclusion and exclusion is possible.

= 1.7 =
* Major bug fix: Relevanssi doesn't kill other post loops on the search result page anymore. Please let me know if Relevanssi feels too slow after the update.

= 1.4.4 =
* Added an option to exclude posts or pages from search results. This feature was requested and provided by Cristian Damm.

= 1.4.3 =
* Indexing of custom fields is now possible. Just add a list of custom field names you want to include in the index on the settings page and re-index.

= 1.4.2 =
* Users can search for specific phrases by wrapping the phase with "quotes".
* Fixed a bug that caused broken HTML in some cases of highlighted search results (search term matches in highlighting HTML tags were being highlighted).
