### New features

[Vim bindings](http://codemirror.net/demo/vim.html): Ctrl-Q is now an alias for Ctrl-V.

[Vim bindings](http://codemirror.net/demo/vim.html): The Vim API now exposes an `unmap` method to unmap bindings.

[FCL mode](http://codemirror.net/mode/fcl/): Newly added.

[SQL mode](http://codemirror.net/mode/sql/): Now has a Postgresql dialect.

### Bugfixes

Fix [issue](https://github.com/codemirror/CodeMirror/issues/3781) where trying to scroll to a horizontal position outside of the document’s width could cause the gutter to be positioned incorrectly.

Use absolute, rather than fixed positioning in the context-menu intercept hack, to work around a [problem](https://github.com/codemirror/CodeMirror/issues/3238) when the editor is inside a transformed parent container.

Solve a [problem](https://github.com/codemirror/CodeMirror/issues/3821) where the horizontal scrollbar could hide text in Firefox.

Fix a [bug](https://github.com/codemirror/CodeMirror/issues/3834) that caused phantom scroll space under the text in some situations.

[Sublime Text bindings](http://codemirror.net/demo/sublime.html): Bind delete-line to Shift-Ctrl-K on OS X.

[Markdown mode](http://codemirror.net/mode/markdown/): Fix [issue](https://github.com/codemirror/CodeMirror/issues/3787) where the mode would keep state related to fenced code blocks in an unsafe way, leading to occasional corrupted parses.

[Markdown mode](http://codemirror.net/mode/markdown/): Ignore backslashes in code fragments.

[Markdown mode](http://codemirror.net/mode/markdown/): Use whichever mode is registered as `text/html` to parse HTML.

[Clike mode](http://codemirror.net/mode/clike/): Improve indentation of Scala `=>` functions.

[Python mode](http://codemirror.net/mode/python/): Improve indentation of bracketed code.

[HTMLMixed mode](http://codemirror.net/mode/htmlmixed/): Support multi-line opening tags for sub-languages (`<script>`, `<style>`, etc).

[Spreadsheet mode](http://codemirror.net/mode/spreadsheet/): Fix bug where the mode did not advance the stream when finding a backslash.

[XML mode](http://codemirror.net/mode/xml/): The mode now takes a `matchClosing` option to configure whether mismatched closing tags should be highlighted as errors.
