Added the AboutSegment feature, you can see this in use on Cosora, it's a little raw right now, but I'm planning to polish it in the next commit. Refactored the code to use switches instead of if blocks in some places. Refactored the Dashboard to make it easier to add icons to it like I did with Cosora. You can now use maps in transpiled templates. Made progress on Cosora's footer. Swapped out the ThemeName property in the HeaderVars struct for a more general and flexible Theme property. Added the colstack CSS class to make it easier to style the layouts for the Control Panel and profile. Renamed the FStore variable to Forums. Renamed the Fpstore variable to FPStore. Renamed the Gstore variable to Groups. Split the MemoryTopicStore into DefaultTopicStore and MemoryTopicCache. Split the MemoryUserStore into DefaultUserStore and MemoryUserCache. Removed the NullUserStore, SQLUserStore, and SQLTopicStore. Added the NullTopicCache and NullUserCache. Moved the Reload method out of the TopicCache interface and into the TopicStore one. Moved the Reload method out of the UserCache interface and into the UserStore one. Added the SetCache and GetCache methods to the TopicStore and UserStore. Added the BypassGetAll method to the WordFilterMap type. Renamed routePanelSetting to routePanelSettingEdit. Renamed routePanelSettingEdit to routePanelSettingEditSubmit. Moved the page titles into the english language pack. Split main() into main and afterDBInit to avoid code duplication in general_test.go Added the ReqIsJson method so that we don't have to sniff the headers every time. Added the LogStore interface. Added the SQLModLogStore and the SQLAdminLogStore. Refactored the phrase system to use getPhrasePlaceholder instead of hard-coding the string to return in a bunch of functions. Removed a redundant rank check. Added the GuildStore to plugin_guilds. Added the about_segment_title and about_segment_body settings. Refactored the setting system to use predefined errors to make it easier for an upstream caller to filter out sensitive error messages as opposed to safe errors. Added the BypassGetAll method to the SettingMap type. Added the Update method to the SettingMap type. BulkGet is now exposed via the MemoryUserCache. Refactored more logs in the template transpiler to reduce the amount of indentation. Refactored the tests to take up fewer lines. Further improved the Cosora theme's colours, padding, and profiles. Added styling for the Control Panel Dashboard to the Cosora Theme. Reduced the amount of code duplication in the installer query generator and opened the door to certain types of auto-migrations. Refactored the Control Panel Dashboard to reduce the amount of code duplication. Refactored the modlog route to reduce the amount of code duplication and string concatenation.

UNSTABLE: Began work on the Nox Theme. Removed the Tempra Cursive Theme. You can now do bulk moderation actions with Shadow. Added: Argon2 as a dependency. The EmailStore. The ReportStore. The Copy method to *Setting. The AddColumn method to the query builder and adapters. The textarea setting type. More logging to better debug issues. The GetOffset method to the UserStore. Removed: Sortable from Code Climate's Analysis. MemberCheck and memberCheck as they're obsolete now. The obsolete url_tags setting. The BcryptGeneratePasswordNoSalt function. Some redundant fields from some of the page structs. Revamped: The Control Panel Setting List and Editor. Refactored: The password hashing logic to make it more amenable to multiple hashing algorithms. The email portion of the Account Manager. The Control Panel User List. The report system. simplePanelUserCheck and simpleUserCheck to remove the duplicated logic as the two do the exact same thing. Fixed: Missing slugs in the profile links in the User Manager. A few template initialisers potentially reducing the number of odd template edge cases. Some problems with the footer. Custom selection colour not applying to images on Shadow. The avatars of the bottom row of the topic list on Conflux leaking out. Other: Moved the startTime variable into package common and exported it. Moved the password hashing logic from user.go to auth.go Split common/themes.go into common/theme.go and common/theme_list.go Replaced the SettingLabels phrase category with the more generic SettingPhrases category. Moved a load of routes, including panel ones into the routes and panel packages. Hid the notifications link from the Account Menu. Moved more inline CSS into the CSS files and made things a little more flexible here and there. Continued work on PgSQL, still a ways away. Guests now have a default avatar like everyone else. Tweaked some of the font sizes on Cosora to make the text look a little nicer. Partially implemented the theme dock override logic. Partially implemented a "symlink" like feature for theme directories. ... And a bunch of other things I might have missed. You will need to run this update script / patcher for this commit. Warning: This is an "unstable commit", therefore some things may be a little less stable than I'd like. For instance, the Shadow Theme is a little broken in this commit.
