After more than two years since 0.9 release, we're close to 0.10! 0.10 branch is already widely used and is thought to be more reliable than 0.9, so it should generally be used for new projects.

We'd love to hear your feedback about 0.10 design and APIs before final release!

Start a discussion in the repository, whether for feedback or if you need help or advice using or upgrading lettre 0.10.

First dev release of the 0.10 branch. Async support is still missing, as well as support for streaming email content.
