Undertow
Undertow 2.4.0 clears three CVEs and finally lands long-open HTTP/2 and timeout requests
A side-by-side editorial comparison of QGroundControl and ROS 2 — release velocity, themes, recent moves, and the top alternatives to consider.
QGroundControl rebuilt its flight UI around touch screens, then went quiet for ten months
QGroundControl shipped v5.0 in July 2025 after five release candidates, patched it through 5.0.8 in October, and then published nothing until a v5.1 release candidate at the end of July 2026. The v5.0 release was the substantive event: the Fly View toolbar, instrument selection, multi-vehicle telemetry and application settings were reworked, MAVLink 2 signing arrived, and the build system was converted entirely to cmake with qmake dropped. The patch line that followed was almost purely crash and platform fixes — Mac notarization, Android SD-card permissions for API 30+, parameter-loading crashes.
ROS 2's release feed announces binary packages and tells you almost nothing else.
ROS 2 is the robotics middleware, and this feed is a package-distribution channel rather than a changelog. Every entry carries the same boilerplate — here are the binaries, check the installation instructions, ignore the auto-generated source links. Three release tracks run in parallel: nightly Rolling builds, patch releases for the current Lyrical Luth distribution, and continued patches for the older Jazzy Jalisco. What actually changed in any of them is not stated here.

The patch line that followed was almost purely crash and platform fixes — Mac notarization, Android SD-card permissions for API 30+, parameter-loading crashes.
The ten-month gap between 5.0.8 and the 5.1 candidate is the clearest signal in these entries: development moved off the release feed rather than stopping, since 5.1 arrives as an RC rather than a patch. The stated design intent from v5.0 — pushing flight-to-flight settings into the toolbar and reserving Vehicle Configuration for initial setup — is a durable direction, and the touch-screen focus points at integrated controllers like Herelink as the target hardware. The RC itself carries no changelog, deferring to an external What's New page.
A v5.1 stable release should follow within weeks of the candidate, and on the v5.0 precedent it will be followed by a run of 5.1.x patches concentrated on platform packaging and crash fixes rather than features.

The visible pattern is distribution lifecycle management, not feature work. Lyrical Luth released in May 2026 on Ubuntu 26.04 and RHEL 10 and has since taken two patch releases; Jazzy continues receiving patches but has dropped Windows binaries under the platform EOL policy now that Windows 10 is end-of-life. Rolling rebuilds nightly whenever jobs have not failed.
Expect the Lyrical patch cadence to continue and Jazzy's platform coverage to keep narrowing as its supported OS versions age out; these notes will not say what the patches contain.
