Version 5.24.0 ### Bug fixes A cursor directly before a line-wrapping break is now drawn before or after the line break depending on which direction you arrived from. Visual cursor motion in line-wrapped right-to-left text should be much more correct. Fix bug in handling of read-only marked text. [shell mode](http://codemirror.net/mode/shell/): Properly tokenize nested parentheses. [python mode](http://codemirror.net/mode/python/): Support underscores in number literals. [sass mode](http://codemirror.net/mode/sass/): Uses the full list of CSS properties and keywords from the CSS mode, rather than defining its own incomplete subset. [css mode](http://codemirror.net/mode/css/): Expose `lineComment` property for LESS and SCSS dialects. Recognize vendor prefixes on pseudo-elements. [julia mode](http://codemirror.net/mode/julia/): Properly indent `elseif` lines. [markdown mode](http://codemirror.net/mode/markdown/): Properly recognize the end of fenced code blocks when inside other markup. [scala mode](http://codemirror.net/mode/clike/): Improve handling of operators containing <code>#</code>, <code>@</code>, and <code>:</code> chars. [xml mode](http://codemirror.net/mode/xml/): Allow dashes in HTML tag names. [javascript mode](http://codemirror.net/mode/javascript/): Improve parsing of async methods, TypeScript-style comma-separated superclass lists. [indent-fold addon](http://codemirror.net/demo/folding.html): Ignore comment lines. ### New features Positions now support a `sticky` property which determines whether they should be associated with the character before (value `"before"`) or after (value `"after"`) them. [vim bindings](http://codemirror.net/mode/demo/vim.html): Make it possible to remove built-in bindings through the API. [comment addon](http://codemirror.net/doc/manual.html#addon_comment): Support a per-mode <code>useInnerComments</code> option to optionally suppress descending to the inner modes to get comment strings. ### Breaking changes The [sass mode](http://codemirror.net/mode/sass/) now depends on the [css mode](http://codemirror.net/mode/css/).
