1.19.0 Breaking Changes

[julian]

Themes should no longer rely on showHidden property in all user account pages (profile/edit/etc.)

It has been replaced with canEdit (which has been around for quite awhile), whose logic is identical. showHidden will be removed in this version of NodeBB.

Some custom themes may introduce additional navigation bars at the top of the page, above the NodeBB header menu.

Persona included code that calculated the height of the header menu and adjusted #panel to start just below it, but it did not account for cases where the header menu is not at the top of the page.

https://github.com/NodeBB/NodeBB/issues/10023

Updated Persona code will do so in v1.19.0 going forward, so any custom themes that use CSS overrides to compensate will need a revisit.

action:category.loaded will not fire when topics are loaded via infinite scroll on category page. use action:topics.loaded instead
https://github.com/NodeBB/NodeBB/commit/36aa60346b26ea0c4c945f6ffe14608baddb1caa

Pages starting with /admin/plugins or /api/v3/admin/plugins route prefixes no longer need to call middleware.admin.checkPrivileges or do their own administrative checks. This is now automatically done.

https://github.com/NodeBB/NodeBB/pull/10035

However, this could be considered breaking if you had a page with a route starting with /admin/plugins/, and expect to have full access to it from non-admins.

middleware.authenticate removed, page and API routes are now automatically authenticated via setup(Page|API)Route. Use middleware.authenticateRequest (if not using route helper) and middleware.ensureLoggedIn instead.

middleware.authenticateOrGuest has been renamed, use middleware.authenticateRequest instead

https://github.com/NodeBB/NodeBB/commit/1a7fffc7e9aab9ad8ea48ad8d99ef2013fc881bf

Topics.getTopicPosts takes a topic object as first parameter.

The commit associated with this issue changes the order of middlewares across all routes using setup*Route helpers.

This sounds serious, but in practice the only thing this affects is that prior to the change, all api requests using bearer token were automatically refused if the site was in maintenance mode. Now, just as admins are able to access the site during maintenance mode, admins can make bearer call authenticated API calls as well.

Tags allow % character now, themes will need to be updated to use tags.valueEncoded instead of tags.valueEscaped
