KUnifiedPush provides push notifications for KDE applications. Push notifications are a mechanism to support applications that occasionally need to receive some kind of information from their server-side part, and where receiving in a timely manner matters. Chat applications or weather and emergency alerts would be examples for that. More technical details about KUnifiedPush are available on Volker's introduction post about KUnifiedPush.

KUnifiedPush provides three possible provider backends for push notifications:

• Ntfy
• Nextpush
• Gotify

The default provider of KUnifiedPush is Ntfy with unifiedpush.kde.org but you can change it to your own server in the System Settings.

Currently both NeoChat and Tokodon integrates with KUnifiedPush as both Matrix and Mastodon support UnifiedPush. There is also ongoing work for weather and emergency alerts.

Packager Section

You can find the package on download.kde.org and it has been signed with Carl Schwan's GPG key.

This is the release schedule the release team agreed on

https://community.kde.org/Schedules/KDE_Gear_24.12_Schedule

Dependency freeze is in around 3 weeks (November 7) and feature freeze one
after that. Get your stuff ready!

Update 1

Great news, everyone! We now have all the necessary components to start creating our 16px icon collection. I believe that we can work on the design and creation of these icons simultaneously.

Here are some general guidelines to consider when designing the 16px icons:

• Our objective is to correlate the designs from the 24px collection to the 16px as closely as possible.
• When in doubt, create an icon that resembles or simplifies the 24px shape.
• Use 1px lines for the icons.
• Utilize the IconGrid16 component to guide your design.
• Once the icon is complete, change the icon color to the “ColorScheme-Text” color.
• To export the icon, use the Icon Jetpack plugin.

I am excited to begin working on this project and would be grateful for any designer assistance that is available. If you need help learning Figma, please don’t hesitate to reach out, and we will gladly provide our support.

If you require edit access to the Figma file for the 16px icon collection, please let me know. I believe that collaboration and teamwork will lead to the creation of an amazing set of 16px icons.

Update 2

Additionally, I wanted to let you all know that I have made some edits to the color scheme of the graphic. I would appreciate any feedback you may have on the changes, and whether I might have missed anything. Let’s work together to create a cohesive and visually stunning icon collection!

Once our colors are aligned to what we need in the system, we will update the issue recently created for this purpose. This issue is under heavy development and things are changing rapidly. Read with caution and expect updates.

https://invent.kde.org/teams/vdg/issues/-/issues/82

Colors in the design system have changed. I need to correlate the colors to the color labels below. It will look a little off for some time. However, the color variables in Figma are updated to the latest feedback. Just this graphic needs the updates as well. Only the color box is correct, not the color names

Update 3

This week we took previously-created Ocean window shadows created by Manuel de la Fuente and integrated them in the design system. The shadow variables in Figma now use Ocean-inspired shadow levels to make them more visible. This is to address feedback on shadows previously being too faint. Hopefully these make a difference.

For some reason that I don't know, the XL shadow looks fainter than the LG shadow, but it seems to be a visual bug in Figma. If you apply the XL shadow, it should appear correctly in your graphics. Update 4

Transition to PenPot is on hold for now until we have the community instance created and path manipulation updates are applied. This would impede us from recreating icons the same way we have them right now.

Let’s go for my web review for the week 2024-42.

You Can’t Make Friends With The Rockstars

Tags: tech, capitalism, marketing, politics, criticism

People have to realize that tycoons like the ones from big tech companies can both be rich and mediocre. They were smart enough to seize opportunities at the right time but they are not exceptional. In fact, they’re even boring and spineless.

The best quote in this paper I think is: “There is nothing special about Elon Musk, Sam Altman, or Mark Zuckerberg. Accepting that requires you to also accept that the world itself is not one that rewards the remarkable, or the brilliant, or the truly incredible, but those who are able to take advantage of opportunities, which in turn leads to the horrible truth that those who often have the most opportunities are some of the most boring and privileged people alive.”

The real problem is that lots of journalists can’t come to term with the fairy tale and so fall prey to all their publicity stunts as if it had any hidden meaning. This is dangerous because of all the political power they try to seize for their own gains.

Meanwhile, “the most powerful companies enjoy a level of impunity, with their founders asked only the most superficial, softball of questions — and deflecting anything tougher by throwing out dead cats when the situation demands.”

Now you can go and read this long piece.

It’s actually unsurprising, all those tech and crypto bros have assets in jeopardy if some regulation is applied to their industry. No wonder they’d support the one with the most libertarian agenda after the current administration which did look into antitrust cases and increased regulation (even though marginally).

Large language models reduce public knowledge sharing on online Q&A platforms

Tags: tech, ai, machine-learning, gpt, knowledge, criticism, research

Now the impact seems clear and this is mostly bad news. This reduces the production of public knowledge so everyone looses. Ironically it also means less public knowledge available to train new models. At some point their only venue to fine tune their models will be user profiling which will be private… I’ve a hard time seeing how we won’t end up stuck with another surveillance apparatus providing access to models running on outdated knowledge. This will lock so many behaviors and decisions in place.

LLMs don’t do formal reasoning - and that is a HUGE problem

Of course I recommend reading the actual research paper. This article is a good summary of the consequences though. LLMs definitely can’t be trusted with formal reasoning including basic maths. This is a flaw in the way they are built, the bath forward is likely merging symbolic and sub-symbolic approaches.

Should you use uv’s managed Python in production?

Tags: tech, python, security, supply-chain, developer-experience

It’s tempting to use uv. It’s probably fine on the developer workstation at this point. It looks a bit early to use it in production though, it’s a bit young for that and carries questions regarding supply chain security still.

https://www.mcc-berlin.net/en/news/information/information-detail/article/49-euro-ticket-resulted-in-significant-modal-shift-from-road-to-rail.html

Bye for now!

We are happy to announce the release of Qt Creator 15 Beta!

I saw this question on KDE forum about how to limit memory usage of a specific application in KDE, using systemd specifically. I did some research on that.

Resource control in systemd

man systemd.resource-control lists plenty of options that we can set to a cgroup. E.g., to limit the memory usage of a service, we can add:

MemoryAccounting=yes MemoryHigh=2G

under the [Service] section of its .service file.

The difference between this and ulimit is that ulimit is per process, while systemd resource control is per cgroup. I.e., the MemoryHigh is accounted to the sum of both the service process, and all sub-processes it spawns, and even detached processes, i.e., daemons.

(That's actually the main point of cgroup: a process tree that a process can't escape via double-forking / daemonizing.)

Apps as systemd services

KDE Plasma launches apps as systemd services. (See this doc and this blog for more details.)

We can find the name of the systemd service of an app like this:

$ systemd-cgls|grep konsole │ │ │ ├─app-org.kde.konsole@0d82cb37fcd64fe4a8b7cf925d86842f.service │ │ │ │ ├─35275 /usr/bin/konsole │ │ │ │ └─35471 grep --color=auto konsole

But the problem is:

1. The part of the name after @ is a random string, changes every time the app is launched.
2. The service is generated dynamically:

$ systemctl --user cat app-org.kde.konsole@0d82cb37fcd64fe4a8b7cf925d86842f.service # /run/user/1000/systemd/transient/app-org.kde.konsole@0d82cb37fcd64fe4a8b7cf925d86842f.service # This is a transient unit file, created programmatically via the systemd API. Do not edit. [Service] Type=simple ...

So if we want to limit the memory usage of Konsole, there's no persistent .service file on disk that we can edit.

Luckily, systemd allows us to create drop-in files to partially modify a service. Also, systemd considers app-org.kde.konsole@0d82cb37fcd64fe4a8b7cf925d86842f.service to be instances of a template named app-org.kde.konsole@.service. (This is how things like getty@tty3.service work.) So we can create a drop-in file named ~/.config/systemd/user/app-org.kde.konsole@.service.d/override.conf with the content:

[Service] MemoryAccounting=yes MemoryHigh=2G

and it will apply to all instances of app-org.kde.konsole@.service, even if there's no service file with that name.

(The file doesn't have to be named "override.conf". Any name with .conf works.)

Then we need to reload the systemd user manager: systemctl --user daemon-reload.

Now we can launch Konsole, and check if the memory limit works:

$ systemctl --user show 'app-org.kde.konsole@*.service'|grep MemoryHigh= EffectiveMemoryHigh=2147483648 MemoryHigh=2147483648 StartupMemoryHigh=infinity

Note: as explained above, the limit applies to the sum of Konsole and all processes it spawns. E.g., if we run kwrite in Konsole, the memory usage of kwrite will be accounted to the limit of Konsole, and the limit we set to KWrite won't apply.

Set defaults for all apps

We can put defaults in ~/.config/systemd/user/app-.service.d/override.conf, and it will match all services whose name starts with app-.

Alternatively, if we run systemd-cgls, we can see that all apps are under a node named app.slice. So we can also put defaults in ~/.config/systemd/user/app.slice.d/override.conf, and all apps will inherit the settings. However, this is different from the previous method, as user services are also under app.slice by default, so they will also inherit the settings.

Being able to build our libraries and applications statically has been on the wishlist since a long time, and recently we made some progress in that direction again. Similar to the the recent Android integration improvements this is also a direct result of Akademy.

Reviving the CI

We had CI for static builds during the 5 era, but we lost quite a bit of coverage there during the transition to 6. However, what we had were only static builds of KDE libraries against a shared build of Qt. That finds some but by far not all issues related to static builds.

The new setup now actually has a static Qt6 to build against, which forces us to also sort out plugin integration correctly. While it is a bit more work to get back to the desired level of CI coverage that way, we will get to a much better result.

Static initialization and CMake

A common problem in static builds is initialization code that is run on shared library loading, as that simply doesn’t exist in static builds, and unless you know what you are doing that will usually be silently dropped from the final executable.

This has previously resulted in various workarounds, such as explicit initialization API (e.g. Q_INIT_RESOURCE), which is easy to miss. With Qt 6 having switched to CMake there’s a new option now though, so-called object libraries. Those are used as implementation details to inject the initialization code from static libraries into the final executable.

From a consumer point of view you get the same behavior as with shared libraries: you link against it and initialization just works. Behind the scenes this adds quite a bit of complexity to the build system though, which then sometimes leaks through into our build system code as well.

The probably most common case is qt6_add_resources. Qt resources need initialization code, so the target they are added to gets another dependency attached to it, an object library containing the initialization.

If that target is a library the additional object libraries need to be installed and exported via CMake as well, to make those available to consumer code (ECM support for this).

add_library(MyLib) qt6_add_resources(MyLib OUTPUT_TARGETS _out_targets ...) install(TARGETS MyLib ${_out_targets} EXPORT MyLibTargets ...)

The OUTPUT_TARGETS part is the new thing to add here (example). Another such case are custom shaders (via qt6_add_shaders), and of course QML modules (more on those below).

Installing QML modules

QML modules created with ecm_add_qml_module also produce object library targets, but since that macro works on a higher level we can handle more of that automatically (ECM MR).

ecm_add_qml_module(mymodule URI "org.kde.mymodule" ... INSTALLED_PLUGIN_TARGET KF6::mymodule) ... ecm_finalize_qml_module(mymodule EXPORT KF6MyModuleTargets)

The EXPORT argument to ecm_finalize_qml_module is the new part here. This takes care both of installing object libraries as well as exporting the QML module itself in the installed CMake configuration file. The latter is needed for statically linking QML modules into the application (see below).

When using ALIAS targets (common in KDE Frameworks, much less common outside of that) we also might need the INSTALLED_PLUGIN_TARGET argument for ecm_add_qml_module(), to make sure the module target name matches the installed alias. That’s not new, but has little practical impact outside of static linking so we have been a bit sloppy there (simple example, complex example).

Importing QML modules

Linking QML modules into the final application binary got a lot easier with Qt 6, thanks to qmlimportscanner.

add_executable(myapp) ecm_add_qml_module(myapp ...) ... if (NOT QT6_IS_SHARED_LIBS_BUILD) qt6_import_qml_plugins(myapp) endif()

That’s it, no more Q_IMPORT_PLUGIN macros or manually listing modules to link. There’s less tolerance for mistakes in the CMake and QML module metadata now though, anything incomplete or missing there will give you linker failures or module loading errors at runtime (see also ECM support for additional import search paths).

Outlook

Since Akademy almost 50 merge requests have been submitted related to this, most of which have already been integrated. With all that it’s possible now to build and run Alligator against a static Qt. Alligator was the first milestone we had picked for this during Akademy, due to being sufficiently complex to prove the viability of all this while not having dependencies that could be adding significant additional challenges on their own (such as the multimedia stack).

However, this work has been mostly done on desktop Linux, and while that allowed for rapid progress it’s the platform this is least interesting for. We yet have to reproduce this on Android, where it probably should bring the most immediate benefit, and of course this removes a big obstacle for potential support of iOS (as Qt can only be linked statically there).

A new Craft cache has just been published. The update is already available for KDE's CD, CI (Windows/Android) will follow in the next days.

Please note that this only applies to the Qt6 cache. The Qt5 cache is in LTS mode since April 2024 and does not recieve major updates anymore.

Happy 28th Birthday KDE!

Sorry my blog updates have been MIA. Let me tell you a story…

As some of you know, 3 months ago I was in a no fault car accident. Thankfully, the only injury was I ended up with a broken arm. ER sends me home in a sling and tells me it was a clean break and it will mend itself in no time. After a week of excruciating pain I went to my follow up doctor appointment, and with my x-rays in hand, the doc tells me it was far from a clean break and needs surgery. So after a week of my shattered bone scraping my nerves and causing pain I have never felt before, I finally go in for surgery! They put in a metal plate with screws to hold the bone in place so it can properly heal. The nerve pain was gone, so I thought I was on the mend. Some time goes by and the swelling still has not subsided, the doctors are not as concerned about this as I am, so I carry on until it becomes really inflamed and developed fever blisters. After no success in reaching the doctors office my husband borrows the neighbors car and rushes me to the ER. Good thing too, I had an infection. So after a 5 day stay in the hospital, they sent us home loaded with antibiotics and trained my husband in wound packing. We did everything right, kept the place immaculate, followed orders with the wound care, took my antibiotics, yet when they ran out there was still no sign of relief, or healing. Went to doctors and they gave me another month supply of antibiotics. Two days after my final dose my arm becomes inflamed again and with extra spectacular levels of pain to go with it. I call the doctor office… They said to come in on my appointment day ( 4 days away ). I asked, “You aren’t concerned with this inflammation?”, to which they replied, “No.”. Ok, maybe I am over reacting and it’s all in my head, I can power through 4 more days. The following morning my husband observed fever blisters and the wound site was clearly not right, so once again off we go to the ER. Well… thankfully we did. I was in Sepsis and could have died… After deliberating with the doctor on the course of action for treatment, the doctor accepted our plea to remove the plate, rather than tighten screws and have me drive 100 miles to hospital everyday for iv antibiotics (Umm I don’t have a car!?) So after another 4 day stay I am released into the world, alive and well. I am happy to report, the swelling is almost gone, the pain is minimal, and I am finally healing nicely. I am still in a sling and I have to be super careful and my arm was not fully knitted. So with that I am bummed to say, no traveling for me, no Ubuntu Summit

I still need help with that car, if it weren’t for our neighbor, this story would have ended much differently.

Despite my tragic few months for my right arm, my left arm has been quite busy. Thankfully I am a lefty! On to my work progress report.

Porting Itinerary and NeoChat to use the KNotification permission API identified two issues around permission checks and callbacks on permission changes that resulted in the application seeing the wrong permission state. That’s fixed now.

Retirement of the Qt 5 CI

With the 24.08 KDE Gear release all our Android apps are based on Qt 6, including their stable release branches. We have therefore started with retiring the Android Qt 5 CI/CD infrastructure, which should save us both maintenance and computing resources.

As Qt 5 is meanwhile lagging behind several Android SDK versions it’s no longer a viable platform for producing APKs that work on up-to-date devices anymore anyway.

Android CI has meanwhile been removed from the KDE Frameworks 5 maintenance branches as well as from a few other libraries that still used it. The removal of Gitlab CI templates, Craft caches and container images will follow.

In particular this means the invent-registry.kde.org/sysadmin/ci-images/android-qt515 container image is deprecated and will be removed eventually. Please get in touch if you are still using this externally. Poppler’s CI was such a case for example.

QML file installation

The QML module macros in ECM used to install QML files to disk, besides bundling those via the Qt resource system as well. While that is still needed on most platforms due to some specific code in Kirigami, it’s unnecessary on Android where we rely solely on the bundled data.

This resulted in unnecessary content in the APKs, which has been fixed and makes all our APKs a bit smaller now.

Translation lookup order

The probably most visible change is a fix for a long standing bug in KI18n’s multi-language fallback lookup order, which would result in applications showing a wild mix of languages under certain conditions.

This happened when the primary device language was set to English but the country to anything but the US or the UK and one or more secondary languages were also selected. While not strictly limited to Android, there’s two factors that made it particularly prone to happen there:

• Newer Android versions allow language and country to be set fully independently, while on many other systems only certain predefined combinations are available.
• The language setting doesn’t just impact application translations but also text input, so many more users have multiple languages configured.

KI18n first looks for a translation for the specific language/country pair and then just the language, before falling back to the next configured language/country pair. If no translation is found it’ll eventually use the English/US source text.

Conceptually this is not wrong, but the implementation missed the fact that there is no “country-less” English translation but only the English/US source text. A configuration of English/Canada and French/Canada therefore previously resulted in a French translation rather than an English one, as it does now.

This has been backported and should be available in all our APKs with 24.08.2 latest.

Runtime language change

Thanks to input from Fabian during Akademy there’s also significant progress on having applications react to system language changes at runtime.

This basically consists of three parts:

• Propagate the native Android system configuration change to Qt, done in Qt CR 596175.
• Reset cached values inside KI18n on system language changes, done in KI18n MR 124.
• Trigger QML binding re-evaluation for i18n() calls on language changes, implemented in KI18n MR 127.

With those three changes applied and a few lines adjusted in the application code to make use of this large parts of the UI already follow system language changes automatically.

It’s far not perfect yet, as there’s more things that need to update in this case than just translated strings. Date/time formatting for example, as discussed in QTBUG-129727. But overall this is already much better than what I had expected and assumed to be feasible with realistic effort.

Dark mode support

As reported previously we have working support for dark mode since 24.08.1, thanks to Julius’ work on icon recoloring.

So far this required minimal changes to applications to enable it though. That has also been fixed, dark mode support is now automatically enabled for all applications using the Breeze style.

Outlook

There’s still more to do regarding Android platform integration. I’d say the two probably most pressing issues are the following:

• On some devices the font size is unusably small, caused by the display scale factor being wrong. Based on some investigation during Akademy the current working theory is that this is a race condition in Qt’s code reading that information. I have no device/setup that reproduces this problem unfortunately.
• Selecting files in the platform file dialog that are located on a cloud storage such as Nextcloud silently fails. That is, to the application selecting such a file looks as if the user had canceled the dialog. Here we know exactly why this happens (it’s explicit code in Qt doing this, for valid reasons), the challenge is rather to find a proper solution.

If you are interested in Android integration for KDE applications, feel free to join us in the #kde-android Matrix channel!

And I’d say it’s a pretty good release! As with all large sets of changes, there are a couple of regressions we’re tracking, particularly around the areas of external monitor brightness and multi-screen performance. They are being actively investigated. Other than those, so far all the issues have been fairly minor, requiring people to jump through various hoops to experience them. We’re still working on fixing them, of course! I’ll be writing up another post soon on these issues, discussing how they snuck into the final release, and what we can learn from the experience.

But in the meantime, here’s the Plasma team’s work from this week:

Notable UI Improvements

Removed some unintentional extra padding around everything on System Settings’ Touchpad page (me: Nate Graham, Plasma 6.2.1. Link):

Notable Bug Fixes

Fixed a regression in Plasma that caused pop-ups of widgets on a Plasma panel to get positioned partially off screen, but only if their parent panel was very small and positioned against on the left or top screen edge (Niccolò Venerandi, Plasma 6.2.1. Link)

Fixed a regression in the new “control all screens’ brightness” feature that caused the brightness slider for external screens to get duplicated with certain screens (Jakob Petsovits, Plasma 6.2.1. Link)

Fixed two minor window focus regressions caused by an intentional change in KWin’s multi-monitor focus behavior (Vlad Zahorodnii, Plasma 6.2.1. Link 1 and link 2)

Fixed a porting regression that caused the virtual desktop switcher OSD to not appear when it should have (Vlad Zahorodnii, Plasma 6.2.1. Link)

Fixed a porting regression that caused the first entry in the clipboard to temporarily not be removable after editing it (Fushan Wen, Plasma 6.2.1. Link)

Fixed a porting regression that caused auto-mounted encrypted disks to mount normally as expected, but not show up correctly in Plasma’s Disks & Devices widget (Bohdan Onofriichuk, Plasma 6.2.1. Link)

Fixed three Plasma crashes affecting the System Tray and Disks & Devices widget under various circumstances (Fushan Wen, Plasma 6.2.1. Link 1, link 2, and link 3)

Fixed a case where Plasma could crash in brightness-related code (Jakob Petsovits, Plasma 6.2.1. Link)

Fixed a bug in our KPipeWire library (which lives in Plasma) that caused screen recordings in Spectacle using the default VP9 video codec to be cut off at the end on slower systems (Arjen Hiemstra, Plasma 6.2.1. Link)

Fixed a bug that caused configuration pages of System Monitor widgets to not be scrollable when needed (Arjen Hiemstra, Plasma 6.2.1. Link)

Fixed an unusual bug that caused the system to fail to log out within the first 50 seconds after logging in, but only when the splash screen was disabled (David Edmundson, Plasma 6.2.1. Link 1 and link 2)

System Settings’ Wallpapers page now has a visible title as expected (Méven Car, Plasma 6.2.1. Link)

The Baloo file indexer service no longer tries to pointlessly index the content of .obj 3D model files (Someone going by the pseudonym “Archaeopteryx Lithographica”, Frameworks 6.8. Link)

Other bug information of note:

• 2 Very high priority Plasma bug (same as last week). Current list of bugs
• 35 15-minute Plasma bugs (up from 30 last week). Current list of bugs
• 107 KDE bugs of all kinds fixed over the last week. Full list of bugs

Performance & Technical

Further optimized Discover’s launch speed (Aleix Pol Gonzalez, Plasma 6.3.0 Link)

It’s Not Easy Being Green: On the Energy Efficiency of Programming Languages

Tags: tech, programming, performance, energy

Nice paper which debunks the choice of the language as an important factor for energy efficiency. The previous papers had a too simple model, this one puts forth a more complete causal model. There are many factors at play regarding energy efficiency, the programming language itself is not really one of them.

We have just switched on the upgrade for KDE neon to rebase on Ubuntu 24.04 LTS.

We do this every two years and the 22.04 LTS base was getting increasingly crusty with old Pipewire causing problems and packages like Krita not compiling at all.

Follow the Noble Upgrade instructions or just click the notification that should appear soon.

The Kubuntu Team is happy to announce that Kubuntu 24.10 has been released, featuring the new and beautiful KDE Plasma 6.1 simple by default, powerful when needed.

Codenamed “Oracular Oriole”, Kubuntu 24.10 continues our tradition of giving you Friendly Computing by integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution.

Under the hood, there have been updates to many core packages, including a new 6.11 based kernel, KDE Frameworks 5.116 and 6.6.0, KDE Plasma 6.1 and many updated KDE gear applications.

Kubuntu 24.10 with Plasma 6.1

Kubuntu has seen many updates for other applications, both in our default install, and installable from the Ubuntu archive.

Applications for core day-to-day usage are included and updated, such as Firefox, and LibreOffice.

For a list of other application updates, and known bugs be sure to read our release notes.

Wayland as default Plasma session.

The Plasma wayland session is now the default option in sddm (display manager login screen). An X11 session can be selected instead if desired. The last used session type will be remembered, so you do not have to switch type on each login.

Download Kubuntu 24.10, or learn how to upgrade from 24.04 LTS.

Note: For upgrades from 24.04, there may a delay of a few hours to days between the official release announcements and the Ubuntu Release Team enabling upgrades.

We’re very happy to announce the latest release of Qt for Python 6.8. With every new release, we try to bring great things with Qt's new features and new trending ideas. For your convenience, you can check out what's new in Qt for Python 6.8 and what’s improved, along with the entire change log.   

Kirigami Addons is out. This releases contains mostly code cleanup and minor improvements. There is netherless a few relevant changes. Thanks to everyone who contributed some code.

New KAppTemplate’s template

A new KAppTemplate is available as a good starting point for application that manage multimedia libraries. It is based on shared design of Peruse, Arianna and the WIP Calligra Launcher.

Hopefully it helps people who want to develop game launchers and other type of specialized multimedia applications.

More templates are planned (e.g. for chat applications), so stay tunned!

FormCard

FormCard is the part of Kirigami Addons that received the most changes in this release. First of all, FormCard now use more consistent spacing and padding, which slighly less horizontal padding. Descriptions for radio and checkbox delegates are also put underneath the delegate’s main text and checkbox, in an effort to make FormCard a bit more compact.

Before After

Additionally FormComboBoxDelegate now lets you display an inline status similar to that is available in other FormCard’s delegates.

Finally FormCard.AboutKDE was renamed to FormCard.AboutKDEPage. This improve the naming consistency with other page compoenents. A compatibility wrapper on top of AboutKDEPage named AboutKDE is still available to not break any existing applications.

Deprecations

The Banner component is now deprecated. Kirigami.InlineMessage now has a position parameter which can be set to Header or Footer. Additionally with KDE Frameworks 6.8 Kirigami.InlineMessage will look exactly the same as Banner! So there is no more reasons for this component to exists in Kirigami Addons.

Other

Kirigami Addons supports static builds with a recent enough version of extra-cmake-modules.

Packager Section

You can find the package on download.kde.org and it has been signed with my GPG key.

Over 180 individual programs plus dozens of programmer libraries and feature plugins are released simultaneously as part of KDE Gear.

Today they all get new bugfix source releases with updated translations, including:

• dolphin: Ignore trailing slashes when comparing place URLs (Commit)
• kate: Fix session restore of tabs/views of untitled documents (Commit, fixes bug #464703, bug #462112 and bug #462523)
• konsole: Fix a crash when sending OSC 4 (RGB) color outside the 256 range (Commit, fixes bug #494205)

Distro and app store packagers should update their application packages.
