Please consult the Help? button again to learn all the syntax changes! The prompt will now also have its width expanded! Updated dependency, knex: 0.20.13 -> 0.20.15. Added new dependency: search-query-parser. Updated all sub-dependencies. Critical? Admins-only API /users/edit will no longer return NEW password salt of the user when randomizing their password. Added page.escape() function to js/misc/utils.js. This will be used to escape input in upload filters input box. The same function used in utilsController.js. Pretty dates will now use / instead of - for date separator. This is due to the fact that date range key for filtering uploads can not accepts dates with - separator. To avoid inconsistency, we will now use / separator. Caching system of album public pages will now be disabled during development (yarn develop). Cleaned up domClick() function in js/dashboard.js. If using date or expiry range keys when filtering uploads, attach client's timezone offset to the API requets. This will be used by the server to calculate timezone differences. Success prompt when changing token will now auto-close. Removed ID column from Manage Users. Improved success prompt when editing users. This will properly list all of the edited fields at once, excluding user group change. Success message for user group change will require a bit more changes on the API endpoint, which is a bit annoying. Rebuilt client-side assets and bumped v1 version string.
