# Open Source in Action #11: 5,000 Merges Crossed, AI in the SDK, and 44 Translators in One Month > Source: > Published: 2026-07-13 10:26:16+00:00 #### Darshan Upadhyay A landmark week — the all-time merge count crossed 5,000, this was the busiest week yet with 578 merges, AI Assistance got its own SDK section, and our translators localized thousands of strings across 40+ languages. Here’s the roundup. ## The Numbers This week: **578 commits merged** by **34 contributors** — a new weekly record. All-time since April 2nd: **5,207 commits merged** from **69 contributors**, with **326 open changes** in review. **Top reviewers this week:** Caolán McNamara (72), Michael Stahl (45), Miklos Vajna (31), Stephan Bergmann (24), Noel Grandin (21), Szymon Kłos (18), Andras Timar (8), Mike Kaganski (6), Gökay Şatır (6), Thorsten Behrens (6). Thank you to every reviewer — Caolán’s 72 reviews this week is remarkable dedication. Welcome to this week’s new contributors: **Kasper Isager Dalsgarð**, **Siam11651**, and **eternal4411** — thank you for your first contributions! ## Localization: 44 Translators, Thousands of Strings Code isn’t the only way this project grows. The __ June Weblate stats__ show an incredible localization effort — **44 translators** contributing across more than 40 languages in a single month. A special thank you to the top contributors: **தமிழ்நேரம்** (Tamil, 752 strings), **Gabriel** (Brazilian Portuguese, 387), and **Rhoslyn Prys** (Welsh, 337) — and to everyone who helped make Collabora Online speak more languages, from Slovenian and Irish to Traditional Chinese, Estonian, Albanian, Armenian, Basque, Kabyle, and many more. Translation is one of the most impactful ways to contribute — it puts the software in the hands of people in their own language. If you’d like to help, __ Weblate__ is open to everyone. ## AI Assistance in the SDK AI Assistance now has its own , making it easier for integrators to configure and deploy AI features. Several improvements landed this week: **SDK documentation section** Darshan __ fixed the AI provider setup flow__ on the desktop app, made the __when nothing is selected in Impress, and__ [AI assistant read slide text](https://gerrit.collaboraoffice.com/c/online/+/6309)__to 300 seconds for more reliable responses.__ [raised the default AI request timeout](https://gerrit.collaboraoffice.com/c/online/+/6547)## Dynamic Arrays and Lambdas: Merged Support for **dynamic arrays and Lambdas** in Calc is now merged — a significant spreadsheet capability, with thanks to Ben for the contribution. Tomaž’s vector rendering also advanced this week with delta changes (only pushing what changed for the current object) and font sending implemented. ## The Length Unit Type: Approved Following the thoughtful __ forum discussion__ from last week, the TC gave the **EMU-based** `Length` **unit type the green light**. The consensus was strong — Michael Stahl noted how valuable strongly-typed lengths were during layout-level redlining work, Caolán is “a huge fan of English Metric Units” as the path to better MS Office interoperability, and the plan includes filing easy hacks so contributors can help with the conversion. A nice bonus: the design won’t allow bare magic numbers anymore — every length must carry its unit explicitly. ## What Developers Are Building **Middle-Click on Hyperlinks:** Darshan fixed __ middle-click opening a hyperlink__ in a new tab instead of pasting ( __), and made the__ [cool#15975](https://github.com/CollaboraOnline/online/issues/15975)__, plus__ [autofilter popup open at a compact width](https://gerrit.collaboraoffice.com/c/online/+/6495)__not opening after a link preview arrives.__ [fixed the hyperlink popup](https://gerrit.collaboraoffice.com/c/online/+/6460)**GIF Playback in Presentations:** Banobe landed __ functionality to play GIFs__ in slideshow, view, and edit modes — with pause and play controls in progress. A long-standing gap now being filled. **Impress Slide Copy — 5x Faster:** Miklos is nearly done with the __ slide copy optimization__ — the third fix is in CI, and the result is roughly 5x faster ODP saves when copying slides. **SmartArt CloneSlides:** Armin is deep in SmartArt CloneSlides work, refining strategies and working through the content-compare approach — with several patches on Gerrit. **Faster Linking:** Caolán found that MSVC’s clang lld-link takes his mergedlib link from **37 seconds to 4 seconds** — a big win for build times. **Accessibility:** Caolán added keyboard-activated context menus that show where the keyboard focus is, and made Shift+F10 act as a dedicated menu button for keyboards without one. **Security Backports:** Attila backported **207 security fix commits** to an older branch — an even bigger effort than last week, carefully working through unit test failures. **Dropping Dead Code:** Stephan is __ dropping the COKit ABI stability machinery__ and removing the broken `--enable-gpgmepp` option — cleaner code, less to maintain.**Memory Leak Fixes:** Michael Meeks is fixing __ producer/consumer mismatch bits__ and related memory leaks. **CIB Office Release:** Adrià is creating a branded CIB Office release from the co-25.04 branch, and preparing a Windows Jenkins agent to double Windows CI capacity. **Dropdown Fixes:** Szymon is fixing dropdowns that could leave a hanging popup on zoom change, and debugging a save failure related to JSDialog commands during background save. ## Design Meeting The UX/UI Design Meeting covered: - **Boundaries icon:** A new icon is needed, with a suggestion to rename it “Outlines / No Outlines” for clarity - **Reviewing mode:** Adding a Reviewing option to the mode switcher - **Settings dialog:** Making the vertical tabs from the iframe-based settings dialog look and behave consistently with the rest of the UI - **Color picker:** Ivana is reworking the color picker widget and finished the Writer template - Easy hacks flagged for newcomers: community page open graph image and adding tooltips ## Design Meeting The UX/UI Design Meeting covered several improvements: - **Presentation console loading indicator:** Szymon noticed the current slide has no frame or loading indicator when it loads slowly — a border and placeholder will be added. - **References tab button:** Ivana suggested shortening “Table of Contents and Index” to just “Table of Contents” to save space. - Icon approvals for Theme, unprotected lock, and collapse/expand - Discussion on GIF playback via WebGL - Mobile hamburger menu and dark mode cursor fixes ## The Community in Action **Chris Sherlock** has been tackling a substantial **coordinate mapper refactor** for the rendering engine — hitting legacy challenges and being grateful for unit tests along the way. He also fixed a macOS crash in the framework environment unit test. Great to see deep engine work from the community. **Ben** contributed the dynamic arrays and Lambdas support that landed this week, and is using the Windows non-headless build — prompting a useful discussion about keeping that build path healthy. The forum’s SmartArt collaboration between **Regina** and **Armin** continues, and Tomaž’s Length unit discussion reached a solid conclusion. It’s worth noting how much good engineering starts as an open forum conversation here. ## Community Calls - **TC Meeting (July 8)**— 9 attendees — Length unit approval, Calc formula behavior, CI turnaround, crash testing - **Collabora Online Weekly Meeting (July 9)**— release schedule, GIF playback, security backports, AI SDK, SmartArt CloneSlides - **UX/UI Design Meeting (July 9)**— boundaries icon, reviewing mode, color picker, settings dialog All minutes on the forum under __ meeting-minutes__. ## Get Involved 69 contributors writing code, 44 translators this month, 5,207 merges. There are so many ways to be part of this — code, translation, testing, design, documentation. - **Try the latest builds:**[collaboraoffice.com/downloads/CODA-Hd7wwbJWxm/](https://www.collaboraoffice.com/downloads/CODA-Hd7wwbJWxm/) - **Help translate:**[hosted.weblate.org/projects/collabora-online/](https://hosted.weblate.org/projects/collabora-online/) - **Easy hacks:**[github.com/CollaboraOnline/online/issues?q=label:easy-hack](https://github.com/CollaboraOnline/online/issues?q=label%3A%22easy+hack%22) - **Community page:**[collaboraonline.github.io/post/communicate/](https://collaboraonline.github.io/post/communicate/) - **Design system:**[collaboraoffice.org/design-system](https://www.collaboraoffice.org/design-system/) - **Forum:**[forum.collaboraonline.com](https://forum.collaboraonline.com/) - **Chat on Matrix:**[#cool-dev:matrix.org](https://matrix.to/#/%23cool-dev:matrix.org) - **Browse open changes:**[gerrit.collaboraoffice.com](https://gerrit.collaboraoffice.com/q/status:open+-is:wip) See you in the code.
