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|WebServer Authorization]] * 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|Using the integrated static file server]] * Adds support for [[multiple user credentials|WebServer Parameter: credentials]] for basic authentication via a CSV file containing usernames/passwords * Adds support for [[serving over HTTPS|Using HTTPS]] as well as HTTP * Adds support for [[authentication via a trusted header|WebServer Parameter: authenticated-user-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|WebServer Parameter: debug-level]] * Experimental support for a new, plain HTML [[single tiddler per page view|Using the read-only single tiddler view]] * Adds a simple level of [[CSRF protection|WebServer Parameter: csrf-disable]] * 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|https://github.com/Jermolene/TiddlyWiki5/pull/2679]]. !!! 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: * [[Table-of-Contents Macros]] * [[tree Macro]] * [[tag Macro]] * [[list-tagged-draggable Macro]] * $:/TagManager Note that using certain characters in tiddler titles will still prevent some features from being used correctly. For example, two vertical bar characters are used in the double curly braces transclusion syntax to separate the tiddler title from the template title: `{{title||template}}`. However, although it would be impossible to transclude a tiddler called `title||template` using that syntax, one could still transclude it using `<$transclude tiddler="title||template"/>`. !!
