 - A next-gen inference engine that enables a much more powerful grammar, allowing you to do things like individually targeting a sequence of scopes, eg `"every line air past bat"`. To learn more, see the initial [#1462](https://github.com/cursorless-dev/cursorless/pull/1462), and then the follow-up [#1463](https://github.com/cursorless-dev/cursorless/pull/1463) if you're addicted to 🤯. Note that this grammar only works for our next-gen scopes, which include most generic scopes (`"line"`, `"token"`, `"word"`, `"character"`, `"block"`), as well as some language-specific scopes. We still have a lot of language-specific scopes to upgrade, as the infrastructure to do so is still quite new. Stay tuned
 - [Stable hats](../hatAssignment.md) ([#1252](https://github.com/cursorless-dev/cursorless/pull/1252)) keep hats from moving around so much while you edit. This change is something you may or may not have consciously noticed, but if you spontaneously experienced a deep feeling of oneness and calm at some point in the past six months, the newly meditative hats might have been the cause 🎩🧘
 - Improved support for very large hats. A trend among users has been to slightly increase their line height (eg 1.6) and then use a very large hat size (eg 70) to make the hats more visible. This works great, but adjacent hats would overlap. Now, we automatically detect clashing hats and stop them from growing horizontally if they'd overlap ([#1687](https://github.com/cursorless-dev/cursorless/pull/1687)). @pokey is now running with a line height of 1.6 and a hat size of 70, after getting serious hat-size envy during some user screenshares on discord 👒.![Big hats](big-hats.png) If you want to join the big hat revolution, say `"show settings phrase line height"` to mess with your line height, then `"cursorless settings"` to mess with your hat size

 # Scope visualizer
 
-The scope visualizer allows you to visualize Cursorless scopes on your code in real time. It is useful to understand how Cursorless scopes work, and is also useful for Cursorless contributors as they develop new scopes.
