Calamares is translated into 58 languages. 59 if you count the latest addition, Macedonian. However, not all the languages have translators, so this is a call for some more translators to sign up.
The Calamares team is happy to announce the availability of Calamares 3.2.2, the second update in the features-and-functionality series of Calamares 3.2.x. Changes in this release require distributions to carefully review the configuration files and settings for Calamares.
Calamares is a distribution-independent system installer, with an advanced partitioning feature for both manual and automated partitioning operations. Calamares is designed to be customizable by distribution maintainers without need for cumbersome patching, thanks to third party branding and external modules support.
As explained before by Adriaan de Groot in this post on his blog, Calamares have participated in the Google Summer of Code 2018.
