Qt World Summit 2026 is moving to a virtual format. After careful evaluation with key stakeholders, we've decided to transition the event from an in-person gathering in Germany to an online experience.

Some of you are following our works to improve connectivity of Qt-based apps. For example, in this blogpost we explained enhacements in the Qt's network stack for more efficient use of RESTful APIs starting with Qt 6.7. So, it might sound we are done with REST. Why bother about OpenAPI then? Well, while around 70% of all web services run on REST, around 20-30% of them use code generated from OpenAPI specification. How could Qt leave that out without helping our users to code less and create more? 

The new Qt 6 OpenAPI module will become available with Qt 6.11 as a Technical Preview. The module introduces the Qt 6 OpenAPI generator, which generates Qt HTTP clients using Qt Network RESTful APIs.

It is important to note here that an OpenAPI generator for Qt 5 has been originally developed by the OpenAPI community. We took it into Qt 6, refactored it, and extended it.

In this blog post, you will learn about the new OpenAPI generator in Qt 6 and see how the new module can be used to implement a simple, Qt-based ChatGPT client application using specification of its API provided in the OpenAPI format.

To make it easier to access the latest AI capabilities, we have updated pre-configured LLMs to newer variants.

Tuesday, 10 March 2026. Today KDE releases a bugfix update to KDE Plasma 6, versioned 6.5.6.

Plasma 6.5 was released in October 2025 with many feature refinements and new modules to complete the desktop experience.

This release adds two months’ worth of new translations and fixes from KDE’s contributors. The bugfixes are typically small but important and include:

The last maintenance release of the 25.12 series is out with the usual batch of stability fixes and workflow improvements. Highlights include small interface refinements such as better dock widget behavior, improved shortcut handling in fullscreen mode, logically grouped marker menu items, and a new option to disable timeline effects in the hamburger menu. The release also brings improvements to multistream clip handling and ripple editing, as well as fixing small memleak in the render widget and a crash in the curve editor. See the changelog below for more details.

The macOS versions will be available at a later time due to technical issues while generating the packages.

Kdenlive needs your support

Our small team has been working for years to build an intuitive open source video editor that does not track you, does not use your data, and respects your privacy. However, to ensure a proper development requires resources, so please consider a donation if you enjoy using Kdenlive - even small amounts can make a big difference.

New Glaxnimate release, source mode in Marknote and S3 support in Dolphin

Welcome to a new issue of "This Week in KDE Apps"! Every week (or so) we cover as much as possible of what's happening in the world of KDE apps.

Office Applications

Marknote Write down your thoughts

It's been a busy week in Marknote again. Valentyn Bondarenko extensively reworked tables to fix rendering issues (office/marknote MR #143 and office/marknote MR #169).

Valentyn Bondarenko also added a new dialog to add note links more easily (office/marknote MR #161) and added subtle animations to various parts of the UI (office/marknote MR #162 and office/marknote MR #168).

Shubham Shinde extended the search function of Marknote to also be able to replace text (office/marknote MR #154).

Siddharth Chopra added a source mode to Marknote, for people who prefer to edit Markdown using a plain text editor (office/marknote MR #118).

Carl Schwan improved the context menu, making it appear directly underneath the button and fixing some accessibility issues (office/marknote MR #166).

Finally, there was quite a bit of polish and refactoring done by the whole team in preparation for the release planned next week.

KMyMoney Personal finance manager based on double-entry bookkeeping

Ralf Habacker added a way to list all your unsaved reports and to delete multiple reports at the same time (office/kmymoney MR #322).

PIM Applications

Merkuro Calendar Manage your tasks and events with speed and ease

Yuki Joou redesigned the schedule view to be less crowded and more concise (pim/merkuro MR #573).

Yuki made it possible to set a start date also for tasks and not only for events (pim/merkuro MR #611). She also fixed the sort button state in the todo view (pim/merkuro MR #612), among other various small issues (pim/merkuro MR #579, pim/merkuro MR #609, pim/merkuro MR #610).

Zhora Zmeikin fixed a crash when editing or creating a new event (pim/merkuro MR #608).

Merkuro Mail Read and write emails

Yuki Joou also worked on Merkuro Mail and fixed various issues when sending emails (pim/merkuro MR #615).

Merkuro Contact Manage your contacts with speed and ease

Finally, Yuki added a way to copy phone numbers from a contact book entry easily (pim/merkuro MR #614).

KMail A feature-rich email application

Albert Astals Cid refactored how temporary files are stored so they are no longer stored in /tmp. This mostly helps in case multiple users use the same machine (pim/messagelib MR #334).

Kleopatra Certificate manager and cryptography app

Thomas Friedrichsmeier changed the font used by plain text email signatures in the Kleopatra and GpgOL.js email viewers to be monospaced, as many signatures depend on that (pim/mimetreeparser MR #91).

Creative Applications

Glaxnimate Vector Animation Editor

This week we celebrated the first release of Glaxnimate as part of KDE. Welcome to the family! The big highlights of this release are better integration with KDE in terms of theming, improvements in the animation timeline, and better SVG export and import. Read more in the full announcement.

In the development branch, Mattia Basaglia continued to improve Glaxnimate. This includes a brand new rendering engine based on ThorVG (graphics/glaxnimate MR #84). This means the rendering is now hardware accelerated, which is faster than the old QPainter-based renderer. Additionally, Mattia improved the backend (graphics/glaxnimate MR #86) and built an experimental WASM renderer based on it for the web (graphics/glaxnimate MR #87).

Multimedia Applications

KPhotoAlbum KDE image management software

Randall Rude updated the documentation (graphis/kphotoalbum MR #73).

Developers Applications

Kate Advanced text editor

Leia uwu fixed Kate so that when renaming a file, any open tabs with this file will also be updated accordingly (utilities/kate MR #2043).

KDevelop Featureful, plugin-extensible IDE for C/C++ and other programming languages

Martin Bednar added support for noexcept in the autocompletion model of KDevelop (kdevelop/kdevelop MR #858).

Network Applications

NeoChat Chat on Matrix

James Graham continued working this week on improving and polishing the new rich text editor in NeoChat (network/neochat MR #2730, network/neochat MR #2729, network/neochat MR #2722, ...)

Joshua Goins disabled the search feature in encrypted rooms as the server is not able to search in them (network/neochat MR #2724).

Kaidan Modern chat app for every device

Melvin Keskin improved the usability of the emoji picker and mentioning participants in a group chat (network/kaidan MR #1522).

System Applications

Dolphin Manage your files

Albert Mkhitaryan added keyboard shortcut support for service menu actions (system/dolphin MR #1167). So now you can assign a shortcut to the context menu actions provided by other applications or user scripts. See doc

Nicolai Sehrt added an option for forcing all tabs in Dolphin to have the same width (system/dolphin MR #1154). Méven Car also updated Dolphin so that, by default, tab widths are automatically determined by their title length (system/dolphin MR #1170).

Méven Car also centered most settings pages to be a bit more consistent with System Settings (system/dolphin MR #1192).

Nekto Oleg improved support for the S3 protocol in KIO-enabled applications like Dolphin. While S3 is commonly associated with Amazon Web Services (AWS), the implementation now also supports custom endpoints and is no longer limited to AWS-compatible services (network/kio-s3 MR #7, network/kio-s3 MR #8 and network/kio-s3 MR #9). Additionally, a new System Settings page makes it possible to configure multiple S3 providers at the same time (network/kio-s3 MR #9 and network/kio-s3 MR #10).

FOSDEM 2026

This year I had the chance to attend my first ever FOSDEM. My main objective there was the GCompris workshop in FOSDEM Junior track. It was an experimental one with the initiative from the organizer since it was only the third year that this track existed.

The workshop had way more adult attendees interested in GCompris for their children than children themselves. So, naturally, it turned more into a dev room than a workshop.

Me, together with the organizers came to a conclusion that GCompris isn't fit for the FOSDEM Junior, at least not in the form of: short presentation -> hands free experience.

The FOSDEM, for me, was very overwhelming. The amount of people in one place as well as having to choose from many different topics, navigating an unfamiliar city had me drained by the end of the first day. Mostly because of that, on the second day I had my workshop and attended only one talk.

Despite that, it was awesome to meet the people of KDE, experience solo travelling for the first time and get to know the core of open source.
