Math
- Breaking change: Alignment points (&) in equations now alternate between left and right alignment

Scripting
- Added function scopes: A function can now hold related definitions in its own scope, similar to a module. The new assert.eq function, for instance, is part of the assert function's scope. Note that function scopes are currently only available for built-in functions.
- Added assert.eq and assert.ne functions for simpler equality and inequality assertions with more helpful error messages
- Exposed list, enum, and term list items in their respective functions' scope
- The at methods on strings, arrays, dictionaries, and content now support specifying a default value

- Fixed bug with underscore in parameter destructuring
- Fixed crash with nested patterns and when hovering over an invalid pattern
- Better error messages when casting to an integer or float fails

Text and Layout

- Added support for passing a array instead of a function to configure table cell alignment and fill per column
- Fixed automatic figure kind detection
- Made alignment of enum numbers configurable, defaulting to end
- Figures can now be made breakable with a show-set rule for blocks in figure
