Open Source in Action #9: 4,000 Merges, Crashes Down to 70, and Vector Rendering Goes Live

Style Previews: Szymon is working on style preview rendering — tackling the tricky problem of identifying styles in the core when localized names differ across languages. Noel helped fix the localization issues, and the team is exploring a custom endpoint to render text with specified properties. Vector rendering for style previews should help significantly here.

Impress Slide Copy Optimization: Miklos is fixing pointless re-parsing of PNG data during ODP save when copying slides — a performance improvement found through profiling.

New Crashreporter Script: Andras wrote a new crashreporter script that caps memory usage, prevents OOM from killing coolwsd, and provides better backtraces — better debugging without risking stability.

cgit.collaboraoffice.com: Andras set up cgit.collaboraoffice.com — a fast, lightweight web interface for browsing the repository.

Removed GStreamer: Michael Meeks removed the GStreamer dependency — one less external dependency to maintain.

Crypto Code Modernization: Michael Stahl is removing old RTL cryptographic code (buggy SHA1, MD5, PBKDF2) and replacing it with OpenSSL/NSS — cleaner, more secure, and less code to maintain.

Document Conflict Dialog: Michael Meeks is improving the document conflict dialog with better error expansion and JSON clues about what’s going on — making conflicts easier to understand and resolve.

Canvas/Slideshow Cleanup: Thorsten filed cool#15913 to track the canvas and slideshow module removal — one of the approved TC cleanups now moving forward.

Namespace Cleanup: Noel continues the cpo:: namespace work and other cleanups, including removing unused bits. The mechanical rewrites are being carefully nursed through CI.

l10n Improvements: Andras killed the old locore l10n machinery and is working on generating UNO command translations at build time.

CI Optimizations — Thank You, Adrià: Adrià Figuera Puig delivered a series of CI improvements this week: flatpak builds now run with limited parallelism instead of using 100% threads, builds are distributed between fermat and mersenne, a new AlmaLinux 9 agent was added, disk space was recovered by cleaning up remaining GitHub workspaces, and Collabora Office snapshots are temporarily running 3x daily during intense testing. Thank you for the steady infrastructure work that keeps everyone else productive.

Dynamic Zoom in Multipage View: Sahil fixed zoom calculations to skip unnecessary invalidation in Writer’s multipage view, and fixed the redline tooltip from blocking text interaction. He’s also working on table cell resize UI for the notebookbar.

CollaboraOffice Improvements: Banobe is fixing the focus issue when switching from viewing to editing and the zoom level retention when switching modes.

Security Backports: Attila backported 155 security fix commits to an older branch — a significant effort to keep older deployments secure. He also got the sectionpages field fix CI-green.

Impress Selection Frames for Draw: Bayram is extending the selection frames work to work in both Impress and Draw, not just Impress. His hyperlink dialog fix

Mention Popup Fix: Darshan fixed the mention popup position inside comments, landed a dark mode icon re-theme fix for CollaboraOffice windows, and blocked cell movement in Calc view mode.
