! Major Improvements

!!  Dynamic Plugin Loading

Plugins [[can now|https://github.com/Jermolene/TiddlyWiki5/pull/4259]] be loaded or deleted dynamically, without requiring a reload -- as long as they don't contain any ~JavaScript modules. Plugins that require a reload are indicated in the plugin chooser in [[$:/ControlPanel]].

The [[plugin listing|$:/core/ui/ControlPanel/Plugins]] and the [[plugin chooser|$:/core/ui/ControlPanel/Modals/AddPlugins]] in the control panel feature several improvements:

* A new ''"Updates" tab'' listing all upgrades available from a plugin library, and a button to update all of them with one click
* Tabs are now used to display plugin libraries within the plugin chooser
* The plugin chooser now displays plugins that provide add-on functionality to another plugin as nested ''"sub-plugins"'', making the main listing easier to navigate
* Plugins may now declare dependencies that are ''automatically installed'' without user intervention
* All plugins are now displayed more consistently, including a concise, informal name (in addition to the description and title)

!! Client-Server Improvements

This release sees several improvements to the client-server configuration:

* Improved resilience to connection errors. Errors encountered by the browser are automatically retried, and when they succeed the associated error messages are automatically removed
* Changes to system tiddlers are now synchronised from the server to the browser
* Deletions of tiddlers on the server are now synchronised to the browser
* New "cloud" page control button with a dropdown menu showing status and additional actions:
** "Refresh from server" to force an immediate check for changes from the server
** "Logout"
** "Save snapshot for offline use" to save a copy of the wiki without the client-server components
** "Copy syncer logs to clipboard" to make it easier to ask end users for debugging information 
* Added "filter" and "exclude" parameters to the [[GET /recipes/default/tiddlers.json|WebServer API: Get All Tiddlers]] endpoint to allow the returned tiddlers and fields to be filtered
* Enhanced LazyLoading to include skinny versions of tiddlers in the HTML file, and to avoid unnecessary loads from the server
* The official plugin library is now disabled when the tiddlyweb adaptor is active
* Internal file system details are no longer exposed to browsers when a file request fails (see https://github.com/Jermolene/TiddlyWiki5/issues/3724)

See the [[pull request on GitHub for more details|https://github.com/Jermolene/TiddlyWiki5/pull/4373]]. 

!! New [[compare Operator]]

[[Added|https://github.com/Jermolene/TiddlyWiki5/issues/4554]] a new filter operator for comparing numbers, strings, dates and version numbers. For example:

:`[[2]compare:number:eq[3]]`
;returns nothing
:`[[2]compare:number:lt[3]]`
; returns "2"
:`[[2]compare:number:eq[2]]`
; returns "2"
:`=1.2 =1.8 =2.3 =3.4 =7.2 +[compare:number:gt[1.5]compare:number:lt[2.5]]`
; returns "1.8" "2.3"
:`[[1]compare:number:gt[2]then[yes]else[no]]`
; returns "no"
