MATE 1.14 has been released and this new release is a little bit different compared to previous release since some of the components are now being ported to GTK+3 only and more will follow in the next 1.16 release in the future.

My current plan is to provide MATE 1.12 for next Slackware 14.2 since it's considered stable and mature. MATE 1.12 also support GTK+3 build, but i still see some major issues unresolved so it's best not to use it and stick with GTK+2 build only. Once MATE 1.12 is released for Slackware 14.2, i can focus on providing MATE 1.14 for Slackware 14.2.

Meanwhile, users who can't wait to try the new MATE 1.14, i have prepared an experimental branch called 1.14 in github in which you can build it from source. For 1.14, i have two options: a mix build between GTK+2 and GTK+3 or fully migrate to GTK+3. For now, this new branch will make a mix build between GTK+2 and GTK+3. Packages that uses GTK+3 are mozo, mate-system-monitor, mate-session-manager, mate-polkit, and mate-notification-daemon. The rest are still based on GTK+2.

Users who do not want to spend time building all the sources can use a precompiled binary which i have uploaded into testing directory in msb repository (only x86_64 for now). The binaries are compiled against latest current (per April 6 2016).

NOTE:
- Help files are now provided, but still not usable unless you have yelp (which requires webkit2gtk available from SBo). It's very time consuming to build so i do not provide a binary package for it.
- By default, audacious will be used as default file manager. Please change it to Caja in System > Preferences > Personal > Preferred Applications.
- New package: libwnck3
- Removed packages:
* mate-netspeed (merged into mate-applets)
* perl-xml-twig (dep of mate-system-tools)
* perl-net-dbus (dep of mate-system-tools)
* system-tools-backends (dep of mate-system-tools)
* liboobs (dep of mate-system-tools)
* mate-system-tools
* gnome-main-menu

Great work willy! Going to build it right now on my slackware64-current virtual machine.

I have not tested it in detail, but it starts correctly and it work

(just, I specify I use gnome base 3.20.0 (glib2-2.48 gtk+-3.20.2 and all other gnome-3.20 base libs and apps)

Thank You Willysr for this. Mate is my DE of choice as of late.

It should work well with newer GNOME/GTK libraries.

Slack64 Current Multilib + XFCE 4.12 + Mate 1.12 (caja,engrampa,atril,pluma + deps)
Upgraded to the pertinent Mate 1.14 precompiled binaries.
No problems as of yet.
Thks, Dick

Looks good here. Slackware Current on a Lenovo. Just needed to remember to enable Tap to Click.

Thanks Willy,

Thank you for your work on bringing MATE to Slackware. I have been using it for several months on -current with great joy.

Please note that i have changed my mind to support 1.12 in the next Slackware 14.2. See my blog post regarding this decission since i can't edit my original post.

In short:
Slackware 14.2 will get MATE 1.14 (mix build by default)
master branch is now tracking 1.14 and GTK3 branch is rebased to master for building GTK+3 version of MATE
binary packages for testing purposes are available in the usual repository (for mix build and full GTK+3 build)

After Current's Thu May 26 updates atril (1.14 mix) no longer supports PDFs !?!
Checking whether a rebuild will resolve the problem -- stay tuned.

Probabbly it need recompil with the new poppler current package

yes, it requires a rebuilt due to poppler update

Confirmed: a rebuild resolves the problem.

i have uploaded a new rebuilt version of atril into both repositories to fix the pdf loading issue due to poppler update, but i don't bump the build number, so you must use --reinstall option with upgradepkg
