See GitHub for detailed change history of this release

New Conditional Operators

Added new Conditional Operators then Operator and else Operator

New Mathematics Operators

Added several new Mathematics Operators for working with numbers: negate, abs, ceil, floor, round, trunc, untrunc, sign, add, subtract, multiply, divide, remainder, max, min, fixed, precision, exponential, sum, product, maxall and minall.

New String Operators

Added several new string operators: match, length, uppercase, lowercase, titlecase, sentencecase, trim, split, splitregexp and join.

Improved Handling of Duplicates in Filters

There is now finer control over TiddlyWiki's default behaviour of removing duplicates from filter results, making it much easier to work with the new mathematics and string operators:

• Added support for new = prefix for merging filter runs without removing duplicates
• Added option for the enlist Operator to not remove duplicates

Improved Keyboard Shortcuts

Keyboard shortcut handling has been significantly improved with the following new global shortcuts (configurable via $:/ControlPanel):

• ctrl-shift-F - focus the sidebar search field
• alt-shift-S - toggle the visibility of the sidebar
• ctrl-shift-A - open the advanced search tiddler

Saving to GitHub and GitLab

Added a Git service saver for saving directly to GitHub and GitLab

• New BrowserStorage Plugin for saving tiddlers in browser local storage

• Optimised the "Classic" storyview to perform much faster when the animation duration is set to zero (approximtely 50% speed improvement was observed in tests opening a storyview with 8,000 entries)

• Improved WidgetMessage: tm-open-window to allow a window title to be specified
