The latest release of the minimalistic web browser Dillo 3.1 has been published. Dillo is written in the C/C++ language using the Fltk library. The browser stands out for its small size, with an executable file size close to a megabyte when statically compiled, and minimal memory consumption. It features a graphical interface with support for tabs and bookmarks, as well as support for HTTPS and a basic set of web standards (including HTML 4.01 and CSS, but without JavaScript support). Additional functionality can be added through plugins, such as plugins for the IPFS and Gemini protocols. The code of the project is distributed under the GPLV3 license.
The last significant update of Dillo was version 3.0.0 in 2011, with the latest corrective update being version 3.0.5 in 2015. Development of Dillo came to a halt in 2017 following the death of a key developer. However, in an attempt to revive the project, Dillo 3.1 has been released in January 2024. In addition, a branch called dillo+ (Dillo Plus) was created in 2023, containing accumulated corrections and updates.
Some of the main changes in Dillo 3.1 include support for floating HTML elements and CSS floats, improved default support for HTTPS, and the ability to use Openssl, Libressl, and MBed TLS libraries for HTTPS functionality. New CSS support has also been introduced, with added properties for attributes like ‘Width’ and ‘Height’, as well as support for ‘min-width’, ‘max-width’, ‘min-height’, ‘max-height’, and ‘display: inline-block’.
