# Changelog
## Version 0.3.0 (April 26, 2023) { #v0.3.0 }
- **Breaking changes:**
  - Renamed a few symbols: What was previous `dot.op` is now just `dot` and the
    basic dot is `dot.basic`. The same applies to `ast` and `tilde`.
  - Renamed `mod` to [`rem`]($category/calculate/rem) to more accurately reflect
    the behaviour. It will remain available as `mod` until the next update as a
    grace period.
  - A lone underscore is not a valid identifier anymore, it can now only be used
    in patterns
  - Removed `before` and `after` arguments from [`query`]($func/query). This is
    now handled through flexible [selectors]($type/selector) combinator methods

    precede the base symbol. The `top` and `bottom` arguments have been renamed
    to `t` and `b`.

    (`[#"string"]`) as well as field access and method call
    without space: `[#emoji.face]`
- New import syntax
  - `[#import "module.typ"]` creates binding named `module`
  - `[#import "module.typ": a, b]` or `[#import "module.typ": *]` to import items

   - Any opening delimiters matches any closing one
   - When matched, they automatically scale
   - To prevent scaling, escape them
   - To forcibly match two delimiters, use `lr` function
