## [0.4.0](https://github.com/joshrotenberg/snodo/compare/v0.3.2...v0.4.0) (2026-10-01)


### ⚠ BREAKING CHANGES

* Snodo.Resource.Template.compile/1 returns {:error, reason} naming the unsupported shape instead of :unsupported, and the struct has new fields. Three kinds of template that compiled and matched URIs before are now refused at compile time: a variable name with a leading dot ({.ext}, {..}), which is RFC 6570 label expansion and before was read as a variable named ".ext"; templates longer than 1,024 bytes; and templates with more than 32 variables. A resource module whose :uri_template is outside the supported shapes and that does not define matches?/1 is now a compile error naming the shape; before, it compiled and matched no URI. A module that defines its own matches?/1 for such a template compiles as before, with or without @impl.

### Features

* RFC 6570 resource templates ([#204](https://github.com/joshrotenberg/snodo/issues/204)) ([5c10d2f](https://github.com/joshrotenberg/snodo/commit/5c10d2f9a4e06590453b60d14aefe985c9e86b8e))
