Libre Arts: Weekly recap — 12 September 2021
Week highlights: new version of BeeRef available, Inkscape updates, VCV Rack 2 teaser, new PipeWire release, and more.
BeeRef 0.2.0
Rebecca Breu released a new version of BeeRef, an amazing free/libre reference image viewer. The main new feature is support for next notes (see my earlier post on the project).

G’MIC is getting new awesome filter
Paint with Brush is the latest addition to G’MIC. Even if you don’t understand German, just scroll to 1:45 to see it in action:
Inkscape updates
Most recently, Mike Kowalski merged his patch that turns the snapping toobar into a drop-down list of options (called popover in GTK).

Personally, I just save the usual snapping options I need into the default template, so I don’t particularly care how exactly they are accessible. What do you think?
In fact, Mike changed various part of the UI over the summer, e.g. you can now configure which parts of the status bar are visible by default. If you never use the drop-down list to navigate layers, you can disable it. And if you never use canvas rotation, you can lock canvas rotation and disable the status bar control over canvas rotation entirely. That gives you more space for context hints.

FreeCAD Trails add-on got its first release
Alright, that actually happened in July but I only noticed that today. Hakan Seven and Maarten Vroegindeweij made the first official release of Trails, the transportation engineering workbench for FreeCAD. And there’s new features coming all the time.

Olive allows previewing waveforms when dragging
Version 0.2 is slowly coming together. I know, it might sound silly, but I’m really glad to have this little feature brought back:

VCV Rack 2 teaser
Andrew Belt released a preview of what’s coming in VCV Rack 2 now expected in November this year.
Highlights:
- Dark room mode (for working at night)
- Better module sections management
- Redesigned module browser
- VST2 plugin to be part of paid version, more options to be added
The bit you are probably most interested in, from a forum post:
VCV Rack Community Edition will be GPLv3 (free/open-source). VCV Rack Studio Edition will be $99 ($149 after release sale) and include VST2 plugin support (+more plugin formats later) and professional support.
And the important part for plugin developers:
90% of plugins will only require a version update and a recompile (a 1-line edit, 15 seconds of work). For the other 10% of plugins using advanced or unstable API features, updating to v2 is easy and involves following a few search-and-replace steps.
There’s a migration guide available: https://vcvrack.com/manual/Migrate2
PipeWire 0.3.35
There’s a new release of PipeWire every other week, here are some of the most (subjectively) interesting changes over the past few weeks:
- Support multiple sample rates in the graph
- S/PDIF pass-through over optical or HDMI is now implemented
- Bluetooth can now automatically switch between headset and audio profile
- Bluetooth codecs are now in separate plugins to make it easier to ship them
- Better JACK compatibility, including improved Catia and Carla compatibility
- Internal latency of ALSA devices can now be configured
- A fast convolver was added to the filter-chain to implement virtual surround sinks or reverbs
Meanwhile, you might want watching Helvum, a GTK-based patchbay for PipeWire.

ROLI files for bankruptcy, LV2 support in JUCE
If you didn’t follow all the news in the past few years, you might be asking yourself, whether ROLI filing for bankruptcy would affect JUCE in any way. After all, there are some very fine free/libre projects using this framework, like the recent DelayArchitect plugin.

Well, the thing is, they already sold JUCE to PACE in April 2020 (and probably started the process a year prior to that, as it is usual in mergers and acquisitions). And the project is rather active, they recently released version 6.1 with broader MIDI 2.0 support, support for VST3 extensions, support for native accessibility frameworks on macOS, Windows, iOS and Android etc. So no, unless you own any hardware instruments they made, you are probably fine.
Speaking of which, LV2 support might land to JUCE-based hosts and plugins after all. Developer reuk writes on GitHub:
We’ve recently been investigating adding LV2 support for both hosts and clients to JUCE, and I feel confident that this feature will be included in an upcoming release. We don’t have a concrete timeline for this work, but hopefully the beta will be ready soon (i.e. months rather than years).
Tutorials
Once you disregard the hilarious “Photoshop editing in GIMP” part of this video’s title, you might find this to be a very nice music-only tutorial on photo manipulation with GIMP.
This is a new Inkscape tutorial by grafikart:
Here is a great caracal speedpainting by Ali Bahabadi, made with Krita. The team recently published an interview with the artist:
This is a looooong no-commentary tutorial on making interior design visualization with Blender 2.9x and Eevee.
Featured Blender artwork: “The Greenhouse” by Laura Ganis.
Each of my weekly recaps involves researching, building and testing software, reporting bugs, talking to developers, actually watching videos that I recommend, and only then writing. Time-wise, that’s between 10 and 20 hours. If you enjoy the work I do, you can support me on Patreon or make a one-time donation.

GIMP and multiple layers cloning
So there was recently a thread by Gleb Alexandrov wondering if he could sponsor some FOSS graphics editor to make the Clone tool work on multiple layers simultaneously.
We’re a bit stuck with one feature that is missing in both @Blender, @Krita_Painting and @GIMP_Official: cloning from/to multiple layers at once.
It’s impossible to tweak PBR texture sets (diffuse, normals, height etc) without it.

Jehan Pages took the challenge and has a preliminary implementation for GIMP.
Working on the ability to clone multiple layers simultaneously in @GIMP_Official, each layer cloning to itself. Code still in “demo” state (already ~ 25 files and more than 1000 lines of code touched) and lot of stuff now need to be fixed, but demo already works quite nicely. 🙂 https://t.co/YScMXIyood pic.twitter.com/mAe5mH3qdS

Krita 5.0 beta1
There have been two Krita releases lately. Version 4.4.8 arrived last week with bugfixes. And then the first beta of v5 was released nearly two weeks ago, representing a few years of work and an insane amount of new features and improvements. If you ever hear them saying that this would be their greatest release ever, this won’t be a marketing ploy, it’s god’s honest truth.
There will be a few more releases before v5.0 can be proclaimed stable and ready to go. Meanwhile, you can download it to try various new things.
Here is a very nice overview:
The project is now also being exploited by scammers (probably not the first time either) which you might take as a sign of Krita going really mainstream.

More multi-page support work in Inkscape
Martin Owens continues hacking on multiple pages support. His private branch now allows opening all pages in a PDF file and saving them back as a multiple pages PDF file. Expect that in version 1.2 some time next year. You can support Martin on Patreon.
Siril changes
The project got another new developer and is rapidly moving towards releasing v1.0. Here is the latest addition:
New in dev: improvement of astrometry (addition of celestial grid, coordinates and compass). Also you can mirror, crop or rotate your image: astrometry is updated and not lost anymore.#freeastro #opensource #astrophotography #science pic.twitter.com/c3TSu8Rul4

gexiv2 needs a new maintainer
Jens Georg announced that he’s about to drop maintaining the gexiv2 library which is a GObject wrapper for Exiv2, the almighty metadata handling tool. This will likely affect projects like GIMP.
Recent history of Exiv2 development is… complicated. In a nutshell, the need to support metadata in CR3 files revealed the need to add support for ISO Base Media File Format which is maybe patent-encumbered and maybe isn’t.
So there have been two camps: people who want it supported and people who want it either not supported or optional. Jens was with the latter.
Since Exiv2 already has a build-time option to enable or disable ISOBMFF support, it’s unclear why Jens would quit maintaining gexiv2. But that’s the reality of it.
Blender
The Blender team announced that version 3.0 is scheduled to be released on December 1. They are still expecting Cycles X, Fields for Geometry Nodes, and the asset browser improvements to be merged before that.
Meanwhile, Andrew Peel continues doing great work with Home Builder:
New version of Home Builder for #b3d coming soon! It’s been a lot of work, but I think it will be worth the wait. pic.twitter.com/thtPXJvCuw

BlenderBIM and Topologic updates
Dion Moult is the true master of 3D, or rather, three D’s: dedication, determination, delivery. The latest update of BlenderBIM comes with 153 new features and fixes, no less. Highlights:
- You can now insert windows and doors into walls, and there’s a project library available for authoring within Blender now.
- The clash detector is back in the game.
- The interfaces for costing, scheduling, and resource management were reworked, and now more start to integrate with one another.
- Support for model checking using the new Information Delivery Specification (IDS) standard is now complete and available thanks to GSoC student Artur Tomczak.
- BCF v3 API and OpenCDE server support now also complete and available thanks to the second GSoC student Prabhat Singh.
- Preliminary openLCA support was added to introduce the beginnings of life cycle and sustainability analysis.
For lotsa more info, please see release notes.
The Topologic project is helluva active as well:
Bringing interactive modelling and visual programming closer. Topologic can now transfer the custom #blender objects’ custom properties to dictionaries of Topologies that contain them. E.g., this will make it far easier to assign space types for energy analysis among many uses. pic.twitter.com/cjq2ibhtH6

Kdenlive is getting new cutting tools
The project has a new contributor, Julius Künzel, who is actively working on advanced cutting tools. He recently added Slip tool, and there is more coming. This work is scheduled for inclusion in version 21.12 expected in December.
Meanwhile, Jean-Baptiste Mardelle is working on further multicam editing improvements.

Cinelerra-GG August 2021 update
This is the third release since William Morrow passed away after a road accident last year. Highlights:
- FFmpeg upgraded to v4.4, this brings 21 new plugins
- New video plugin called Speed PerCent
OpenShot 2.6.0
It’s been almost 1.5 years since the previous release, Jonathan Thomas and Frank Dana have been really busy, hence this slew of changes available in newly released v2.6.0, some of them being:
- Motion tracking, object detection, and stabilization now available
- 9 new audio effects, including compressor, delay, and an EQ
- New transform tool to resize, rotate, move, scale etc.
- Improved snapping
There’s a video that will walk you through the changes:
I’ve given this version some quick testing. Unfortunately, OpenShot is still very much not my cup of tea for a variety of workflow and UX reasons. But I know that it has an army of devout users who swear by it, so I’m happy for you!
LibreArp 2.1
This little known LV2 arpeggiator recently went through UI rewrite, there’s a massive amount of changes in both v2.0 and 2.1 released just two weeks apart from each other, so I guess… Feel free to just treat it as a whole new plugin then? 🙂
