• AdminCP menu entries now support two new parameters: menu_checks allows you to define additional input key => value mappings in an array which will also be checked to determine if you are viewing the menu entry page in question, and menu_controller allows you to override the controller check when generating the menu key. This is used by Pages, for instance, to support highlighting the dynamically generated menu entries.

• Application.php files for individual applications can now define a sitemapLinks() method to return additional links to add to the sitemap without having to generate an entire sitemap extension. This should only be used to return a small handful of static links, and sitemap extensions should be used to add a dynamic number of links.

Changes affecting third-party developers and designers

• jQuery has been updated to version 3.5, which has some breaking changes. However, we are also including jQuery Migrate which re-implements some older APIs while functionality is updated. Check the browser console while developing your applications and aim to resolve any JQMIGRATE messages that your app in particular generates. Migration messages generated by Invision Community and its dependencies will be fixed over time. See https://github.com/jquery/jquery-migrate/blob/master/warnings.md for more information.
• All AdminCP controllers now require CSRF-protection as on the front-end.
• File storage handlers must now handle chunked uploading differently. See \IPS\File\FileSystem::chunkInit(), \IPS\File\FileSystem::chunkProcess() and \IPS\File\FileSystem::chunkFinish() - these 3 need to be implemented, replacing the previous chunkAppend() method.
• Building applications will now store a flag for which module is set as the default, and that module will be set as the default module when users install your application (or upgrade your application, if no other module is already set as the default). The default module will not be reset or changed during upgrades automatically. If you must change a default module during the upgrade, you may do so manually with a database query, however be mindful that administrators may legitimately wish to adjust which module is the default in any given application.
• Pages comment and review loading now enforce that the comment or review belongs to the specified database. You cannot use \IPS\cms\Records\Comment::load() to load a comment or \IPS\cms\Records\Review::load() to load a review, but must ensure the comment or review ID you are loading belongs to the class it is loaded through (e.g. if loading comment ID 1 and it belongs to database ID 1, you must now use \IPS\cms\Records\Comment1::load()).
• Dynamic Charts now support the ability to download the generated data as CSV. Details here:
• BBCode parsing is now considered deprecated, and may be enabled or disabled. If you must rely upon BBCode parsing occurring, you may need to parse content through \IPS\Text\LegacyParser instead of the general \IPS\Text\Parser class.
• The ability to use SQLCALCFOUND_ROWS has been removed globally because it has been deprecated as of MySQL 8.0.17. If you relied on this functionality to fetch a total row count (i.e. for pagination purposes), you will need to update your code to explicitly run a count query to fetch the total row count separately.
• Added a new parameter to \IPS\Content\Item::markRead() to force an update even if the content already appears to be read.
• The postComplete() method for a Queue background task (if defined) was not previously called when preQueueData() returned NULL, which has changed. The postComplete() method will now be called, and a new parameter $processed can be checked to determine if the queue task did anything or not. If you define the postComplete() method for any Queue background tasks, you should add a second parameter $processed which defaults to TRUE.
• A new variable was introduced in \IPS\Dispatcher\Controller to allow you to set specific controllers and controller actions as "non-content specific", so that google ads & co aren't served on this pages. Please keep this in mind for your custom controllers.
• The \IPS\Helpers\Form\Node class was incorrectly relying on "view" permissions in some cases to determine if a node should be included in the form helper select box (even in areas like the AdminCP where the nodes should be available even if you cannot view them). This should not pose any issue for third parties, but you may wish to review your node helper instances and ensure all nodes are always shown when appropriate (e.g. nodes the administrator cannot view on the front end are still available for selection in the AdminCP when appropriate, or that they are not available to select when they shouldn't be selectable).
• Applications built in Invision Community 4.5 will automatically remove deleted language strings when your application is upgraded.
• A new background task PruneLargeTable has been added which can aid in pruning potentially large database tables.
• The \IPS\Db::i()->delete() method can now accept an array for $statementColumn and will join the inner table on instead of using a subselect.
• Some (but not all) implementations of loadFromUrl() previously performed permission checks, however these have been removed and it is now up to user-land code to perform these permission checks when needed.
• An exception is now thrown if an invalid file storage exception is called in \IPS\File::get() when in development mode.
• Added a $rowClasses param as the last param when creating a form field, that can be used to pass additional CSS classes to the form row template.
• Added a urlencode and rawurlencode option for language strings which will urlencode/rawurlencode the entire language string that is returned.
• Added a $currency parameter to \IPS\nexus\Package::price() to override default customer's currency.
• Simplification of the .ipsResponsive classes to allow them to be used in a larger variety of cases.
• Removed image dependency from .ipsStepBar allowing its color scheme to be edited via css.
• Removed icomoon dependency from css. The icons which were created using this font have been replaced with FontAwesome and pure css equivalents. The icomoon files are still present, so they can be imported using custom.css if necessary.
• A data-role attribute has been added to list items in .cAuthorPane_info, allowing for more accurate CSS targeting of author stats.
• The padding and margin values under the .cSearchExpanded class have been replaced with a pseudo element. If you have modified this class or #elSearch, some minor adjustments may be required to ensure the alignment of your search form is correct in your theme.
• Headers (.ipsWidgettitle, .ipsTypesectionTitle, etc) will now respect the font-family of the body element if the "Headline Font" setting is set to Default.
• Changed the default font-family from a Helvetica stack to a system-ui stack.
• Centralised display name checks in a new method \IPS\Login::usernameIsAllowed().
• Added a new method \IPS\Text\Parser::hasContent() that determines if any actual content was supplied from an editor. This can be used in templates (for example) to adapt the layout depending on whether a node has a description or not.
• New CSS utility families have been added: ipsFlex, ipsPad (updated to include more variants) and ipsMargin. All support responsive prefixes (md: and sm:) to control how the classes behave at different device sizes. For example, ipsFlex-fd:row sm:ipsFlex-fd:column would make an element flex-row by default, but flex-column on small screens. Similarly, ipsMargin_top sm:ipsMargin_top:half would apply 15px margin-top by default, but only 7px on small screens. See the CSS framework for complete class availability.
• All hex values inside theme .css files have been replaced with {theme="setting"} equivalents, allowing for a more consistent color scheme, especially with dark themes.
• The HTML structure for the navigation bar on .ipsLayout_minimal pages is now identical to regular pages.
• Changed \IPS\Member::generateLetterPhoto() to a public method and added an option to return the letter and color, vs the entire SVG data string.
• Changed polls to use the poll $url rather than the general form action in the pollForm template.
• Added new font scale theme settings to keep typography on a fixed scale where appropriate. To aid usage, a new {fontsize} plugin tag is included, which accepts either a font scale size key (e.g. small, medium) or a number in pixels. The new global font scale setting will automatically be honored when the {fontsize} tag is used.
• Added \IPS\Helpers\Form\Enum which can be used to display a ChecboxSet or Multi-Select box depending on the amount of options present on the form. Useful when Checkboxes are ideal UI, however the amount of options can be dynamic, which can cause issues when many options are present.
• Applications and Plugins can now create language strings using \IPS\Lang::saveCustom(). The first parameter will now accept either a string or an instance of \IPS\Application for an Application, or an integer or an instance of \IPS\Plugin for a plugin.
• CodeMirror Form Helpers can now accept a tagLinks option. When used, links (similar to links built in the header of the AdminCP) can be added to the headers for that specific section to allow direct linking to another area. Note, however, that if you need to perform AJAX functions, you will need to include that manually in any JavaScript controllers you implement on the form.
• CodeMirror Form Helpers can now accept a tagSource option. This should be an \IPS\Http\Url instance, which will then load any tags via AJAX.
• \IPS\Data\Store::i()->failedMailCount has been replaced with a new method \IPS\Email::countFailedMail() for a real time count
• Settings have been added to themes to set a maximum logo size at large, medium and small device sizes.
• The getQueryWhereClausemethod in Bulk Mail Extensions should return only a simple array with the where clause instead of a DB where clause with the parameter binding.
• Applications and Plugins now have the ability to include Pages templates when they are built. The templates will be imported when the plugin/application is installed.
• \IPS\File::get() now has a third parameter to accept an integer of the filesize if it is already known. This is a performance improvement for when filesize() is used.
• If file storage contents are declared 'private' (and use S3 storage) the REST API will now return a signed URL for these resources.
• The \IPS\Content\Content::urlFromIndexData() method now accepts a third parameter definining the do action, similar to the existing url() method.
• Fixed an issue where the subnode flag may be lost when mass moving or deleting content.

Deprecations

• Core: Apc, Memcache, Wincache and Xcache caching engines, we recommend using Redis instead.
• Core: We will no longer address any issues specific to Internet Explorer 11 and below and will not ensure compatability with those versions.
• Core: BBCode parsing support - upgrading users will be asked during upgrade if they wish to retain BBCode parsing support, while new installations will have the option off by default. BBCode parsing may be removed entirely in a future release.
• Commerce: Authorize.net Payment Gateway.
• Commerce: Web Hosting & Domain support.
• Downloads: REST API 'files' response in REST API, see /downloads/files/{id}/download instead.
