Download Splintermail 0.4.2

Released on 13 May 2025.

Version 0.4.2 is a bugfix release. Updates in libuv v1.51.0 change behaviors that caused issues on linux installations. Also, upcoming changes to LetsEncrypt required support for certificate lifetimes as short as 6 days.

Email us if you would like to use Splintermail with an email client that isn't yet supported, and we will prioritize support for that client.

All source code is availaible on our Github page.
