Release Notes

djc/askama (askama)

v0.12.0

0.12.0

After 13 months of development, we're happy to announce the 0.12.0 release of Askama, the type safe, compiled Jinja-like template engine for Rust. For this release, @​Kijewski contributed most of the changes -- @​vallentin and @​djc are the other team members. This releases comes with integrations for Actix-Web 4, Axum 0.6, Gotham 0.7, hyper 0.14, Tide 0.16 and Warp 0.3. We removed our Iron integration, since this framework no longer seems to be actively maintained.
