Ardour has just seen a new major release, version 4. Since the last release, there have been over 4,000 commits.
Ardour has seen a lot of infrastructure work and now uses a new graphics engine (cairo) for the editor window. You can now also use other audio backends other than JACK, for example you could use ALSA, although JACK is still the recommended backend.
Things have been moving along for the Guitarix project lately. First of all, they have redesigned their website and forum. Also, their website now has a new domain at guitarix.org, while the source code is still hosted at sourceforge.
Rui Nuno Capela has been on a pre-LAC2015 release frenzy with his Q-stuff suite of software. In the past week he has released updates for QjackCtl, Qsynth, Qsampler, QmidiNet, QmidiCtl and of course Qtractor. You can find full details about these releases over at rncbc.org.
Version 0.9.5 of Giada Loop Machine has been released. This version, codename 'Nabla Symbols', has a number of refinements, as well as permanent MIDI mapping.
Guitarix developer, Hermann Meyer has just announced a new LV2 plugin for the Guitarix LV2 plugin suite, Gxjcm800pre, a JCM800 simulation.
This simulation had previously been available within the Guitarix standalone program but is now also available as an LV2 plugin. The LV2 plugin includes tone, presence and master controls so that the full JCM800 is simulated.
Due to a recent call from the Guitarix devs for a graphic designer, Markus Schmidt from Calf Studio Gear has got in touch with them and taken on the task. For those who don't know who Markus is, he has not only created a lot of the Calf plugins but is also the guy responsible for their graphical interfaces.
Also, they are still looking for anyone interested in helping them do a complete redesign of Guitarix, so if you are handy with graphics do get in touch with the Guitarix guys.
