This release introduces support for [Zsh](https://www.zsh.org/) in the
parser and formatter, which was tracked in issue
[#&#8203;120](https://redirect.github.com/mvdan/sh/issues/120) alongside
the label <https://github.com/mvdan/sh/labels/zsh>. While support is not
complete, it should be far enough for many use cases.

This release also drops support for Go 1.24 and includes many other
enhancements:

- **cmd/shfmt**
  - Exit with a non-zero status when `-l` prints any filenames
- `shfmt -version` is now derived from the git current tag, dropping the
`-ldflags` workaround
- **syntax**
  - New nodes types and node fields are introduced alongside `LangZsh`
- `LangVariant` is now a bitset, allowing the use of sets like
"Bash-like"
  - Add `InteractiveSeq` and `StmtsSeq` iterator methods for `Parser`
  - Stop exposing the internal buffer in `Printer` via struct embedding
  - Support the use of brace expansions like `declare {a,b}_c=value`
- Fix a bug where POSIX and Bash incorrectly allowed empty command lists
- **interp**
  - Add support for `shopt -s dotglob` and `shopt -s extglob`
  - Add support for simple uses of `!(expr)` extended glob patterns
  - Support more builtin flags for `declare`, `type`, `read`
  - Fix various bugs relating to nulls, errors, and arrays
- **expand**
  - Add `Config.DotGlob` and `Config.ExtGlob` for the interpreter
  - Add `Variable.Flags` to get the one-character `declare` flags
  - Do not force env vars on Windows to be uppercase
  - Fix various bugs relating to glob pattern matching
- **pattern**
  - Add `GlobLeadingDot` and `ExtendedOperators` for the interpreter
  - Add `NegExtGlobError` to mark the use of `!(expr)` negation patterns
