announcing lettre 0.10

We are pleased to announce the 0.10 release of lettre, an email client for Rust programs. lettre allows sending emails from Rust applications, focusing on ease of use, security by default and modern features (like support for full internationalization). It does not aim at implementing email RFCs extensively, but only what is necessary for our needs.

lettre provides a type-safe email builder, several transports, tls support with rustls and native-tls and async support with tokio and async-std.

lettre is now used by many projects, including crates.io itself!

changes in 0.10

Since 0.9 release in March 2019, a lot of changes were made. Key improvements are:

0.10 has counted 5 alpha releases since May 2020, is already quite widely used and is already thought to be more reliable than 0.9.

the road to 1.0

0.10 is a first step on the road to 1.0, as all major features required for a stable version are implemented.

We’d love to hear your feedbacks about 0.10 design and APIs to be able to fix problems in lettre before 1.0.

community

lettre was built 45 contributors since its creation, including 25 for 0.10. Thanks a lot for your help!

The 0.10 release was made possible by the amazing work of @paolobarbolini who joined the maintainer team this year, and lead the development efforts since. Issue and pull requests response time has considerably lowered too, making lettre a more welcoming project for contributors and users.
