Cinnamon 3.2.0 has just been tagged in the github repository and it will be polished in preparation for upcoming Linux Mint 18.1 which will be released around December.
Cinnamon 3.2.x will highlight a new interesting feature: Vertical Panels. This is the most interesting feature as it will add capability to add vertical panel in your desktop. GNOME 3 has been using it for a while, but Cinnamon developer decided to implement this in 3.2 with some considerations.
There's a noticeable performance improvement on this release as it's getting less lag in my desktop compared to previous 3.0 releases. I'm very pleased with the results and looking forward for more performance improvements made by the upstream developers.
SBo or MSB projects, there's no guarantee that it will build cleanly under clean Slackware 14.2 installation. For that reason, i will try to test this under clean virtual machine on top of clean Slackware 14.2 installation.
For those who want to build this packages via source, i have pushed 3.2-prep branch in github which contains an updated scripts for building Cinnamon 3.2.x. This branch is based on 14.2 branch, so it's very suitable for building Cinnamon 3.2.x packages on Slackware 14.2. There's two packages that are not yet there since it's only available in master branch: mint-y-icons and mint-y-theme.
There's a new package added for this new Cinnamon: autoconf-archive. It is required to build some Cinnamon packages (i found it while building cinnamon-control-center) and it also triggers a change in gnome-common package to use --with-autoconf-archive configure parameter so that the resulting output do not overlap each other.
While i conduct more testing on a clean VM, i posted some screenshots for early Cinnamon 3.2.0 preview. Feedbacks, bug reports and suggestions can be sent via github issue tracker or via email.
