!! Major Improvements

!!! Node.js HTTP Server

The HTTP WebServer functionality has been significantly improved:

* Adds ability to make a wiki that is read-only for anonymous users, but allows editing for users who log in
* Adds support for serving static file attachments over HTTP
* Adds support for multiple user credentials for basic authentication via a CSV file containing usernames/passwords
* Hides UI features like the new tiddler button and the edit button when the user only has read-only access to the wiki
* Adds support for serving over HTTPS as well as HTTP
* Adds support for authentication via a trusted header, making it easier to integrate with corporate single sign on (and Windows authentication)
* Adds support for more fine grained authorisation (ie granting/denying individual users read/write permission to resources)
* Better debugging information
* Experimental support for a new, plain HTML single tiddler per page view
* Adds a simple level of [[CSRF protection|WebServer Parameter: csrf-disable]]
* Deprecating the existing `--server` command in favour of a new  `--listen` command using the new NamedCommandParameters support for named parameters that can be specified in any order
* Refactoring routes as separate modules, making it easier to extend the server with new functionality

See WebServer for more details, or [[see the changes on GitHub|https://github.com/Jermolene/TiddlyWiki5/pull/2679]].

!! Comment Plugin

This release [[adds|https://github.com/Jermolene/TiddlyWiki5/commit/acaa07a964a004759ddb8fb755484918b3322815]] a new commenting plugin -- see $:/plugins/tiddlywiki/comments

!!! Single Tiddler Mode ([[#3412|https://github.com/Jermolene/TiddlyWiki5/pull/3412]])

"Single tiddler mode" fixes a long-standing problem with the ''zoomin'' story view whereby although only a single tiddler was displayed at once, all previously navigated tiddlers were actually open, but hidden. This had a significant effect on performance, and a number of unexpected side-effects that hampered usability.

Single tiddler mode changes navigation to replace the story list with the target tiddler, rather than the usual behaviour of adding the target tiddler to the story list. It is engaged automatically when selecting the ''zoomin'' story view.
