0.8.0
d0d5168

After 3 months of development, I'm happy to announce the availability of version 0.8 of Askama, the type-safe, compiled Jinja-like template engine for Rust -- all the more so because it has taken me way too long to push out this release due to an exceedingly busy period in my personal life.

Askama 0.8 is up to 2 times as fast as 0.7.2, thanks to performance improvements contributed by @botika and @YossyJ. For comparisons to other template engines, please look at the template benchmarks repo. The largest feature this time around is the newly added support for pluggable escape engines and formats. By adding just a few lines to the askama.toml configuration file and writing a simple implementation of the Escaper trait, Askama can use custom code for escaping, such as for different formats (LateX or shell) or with even more optimized performance (using SIMD).
