## [v0.1.1] — 2026-04-16

This release makes binary-only changes. Once installed, any existing use of
re2 v0.1 will get its benefits on reload without needing to
`ALTER EXTENSION UPDATE`.

### ⚡ Improvements

*   Added support for Postgres versions 13+ (previously 16+).

### 📚 Documentation

*   Documented the use of the variadic list of pattern arguments in the
    `re2multimatch*` functions and how an array can be passed via the
    `VARIADIC` keyword to mimic the array syntax for the corresponding
    ClickHouse functions.
