Major Improvements
Global Keyboard Shortcuts
This version introduces new infrastructure to handle global keyboard shortcuts. The core ships with the following shortcuts:
- alt-I (or ctrl-I on Mac) - New image
- alt-J (or ctrl-J on Mac) - New journal
- alt-N (or ctrl-N on Mac) - New tiddler
See How to create keyboard shortcuts
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 (with the editing UI hidden), but allows editing for users who log in
- 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 static file attachments over HTTP
- Adds support for multiple user credentials for basic authentication via a CSV file containing usernames/passwords
- 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
- Deprecating the existing ServerCommand in favour of a new ListenCommand 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.
Special Characters in Tiddler Titles
In previous versions of TiddlyWiki, there were some special character sequences in tiddler titles that would break certain features. For example, a tiddler title ending in double quotes would cause the Table-of-Contents Macros to render incorrectly.
As of 5.1.18, many of these problems have been fixed by refactoring the features to use the latest abilities of wikitext:
Note that using certain characters in tiddler titles will still prevent some features from being used correctly. For example, two vertical bar characters are used in the double curly braces transclusion syntax to separate the tiddler title from the template title: {{title||template}}. However, although it would be impossible to transclude a tiddler called title||template using that syntax, one could still transclude it using <$transclude tiddler="title||template"/>.
Plugin Improvements
- KaTeX Plugin – the KaTeX Plugin has been updated to KaTeX v0.10.0. The plugin now incorporates an extension for chemical formulae
- Comment Plugin – this release adds a new commenting plugin – see $:/plugins/tiddlywiki/comments
- AWS Plugin – support for running TiddlyWiki as a Lambda function has been improved with support for GZip compression of the JSON payload

- Added current username (if set) to the title of draft tiddlers, making them easier to identify in multiuser scenarios

- Refactored the tiddler info panel to make it be dynamically built from the tag
