Dillo release 3.1.0

Released on 2024-05-04

Summary of changes

Since the last release 3.0.5 from 2015 a lot of things have happened to the Dillo project.

Here is a short timeline to put things into perspective:

• On 2016, the main developer of the layout engine, Sebastian Geerken, passed away.
• On 2017, the development stopped.
• On 2019, the last email from Jorge Arellano Cid, the lead developer of Dillo, was recorded by the mailing list.
• On 2022, the domain dillo.org was lost.
• On 2024, an attempt to resurrect the project began by Rodrigo Arias Mallo.

This release contains a lot of changes accumulated from the 2015-2017 period, as well as fixes and small features introduced in 2024. Here is a summary:

• Add support for floating HTML elements, which involved a big redesign.
• Add support for OpenSSL, LibreSSL and mbed TLS for HTTPS, which is now enabled by default.
• Add a CI pipeline to build Dillo on Ubuntu, MacOS, FreeBSD and Windows (via cygwin).
• Add automatic HTML rendering tests.
• Improve and extend the Dillo manual.

In memory of Sebastian Geerken.
