The new rattler-build
We are releasing a Rust based conda-build replacement that builds cross-platform binary packages much faster.
Repodata patching: how conda-forge keeps compatible
Keeping packages in a large repository compatible over time is tricky. conda-forge has a highly useful mechanism for that: repodata-patching.
Introducing Rattler: Conda from Rust
At prefix.dev we love Rust, but using conda/mamba from Rust is hard, so we started building Rattler, a set of crates that offer clean, compartmentalized building blocks for package management.
