ESP-IDF
Espressif keeps five ESP-IDF branches alive and tells you almost nothing in the release notes.
A side-by-side editorial comparison of Node.js and OpenTripPlanner — release velocity, themes, recent moves, and the top alternatives to consider.
Three release lines moving in lockstep, with the security train setting the pace.
Node is maintaining three lines at once — 26.x Current, 24.x 'Krypton' LTS and 22.x 'Jod' LTS — and the window is dominated by a single coordinated security release on 29 July that shipped the same eleven CVEs to all three branches simultaneously. Three of those were rated High, and three of the eleven were in the permission model itself. Feature work continues on Current at roughly a two-week minor cadence, with 24.x absorbing the backports in large batches.
OpenTripPlanner finished a multi-year migration by deleting its REST API.
OTP releases roughly twice a year and keeps its notes to a handful of notable items, deferring the rest to external changelogs. The recent line has been about API consolidation: 2.6.0 disabled the legacy REST API by default and made the new debug client the default, 2.8.0 removed the REST API outright, and 2.9.0's only listed change is a move to Java 25. Feature work in between went into SIRI extra calls, GTFS-RT platform and headsign changes, and transit filters on the GraphQL planConnection query.

Two things are visible across these releases. The crypto layer is being systematically rebuilt — OpenSSL 3, BoringSSL and legacy backends were split apart, FIPS handling for Argon2 was corrected, and key loading is moving to OpenSSL STORE loaders — which reads as preparation for supporting more than one TLS backend cleanly. Separately, the permission model has stopped being a side experiment and is now generating its own CVEs, which is what happens when a security feature starts being relied on. Observability is the third thread, with Perfetto being wired into the build and event-loop delay sampling moving per-iteration.
Expect the crypto backend split to keep producing SEMVER-MINOR changes on Current as key handling migrates to STORE loaders, and expect the next 24.x LTS drop to be another large batch backport rather than a steady drip. Given three permission-model CVEs in one train, further hardening there is the most likely source of the next security release.

Feature work in between went into SIRI extra calls, GTFS-RT platform and headsign changes, and transit filters on the GraphQL planConnection query.
The GraphQL API is now the only API, and the deprecation of plan in favour of planConnection back in 2.7.0 shows the same consolidation happening inside it. Alongside that, the real-time surface keeps growing — SIRI Lite, extra calls, GTFS-RT support for new and replacement trips — while graph build memory consumption gets cut release over release. The 2.9.0 release being a Java version bump and nothing else suggests the API work has run its course.
With the REST removal done and the runtime moved to Java 25, the next release is more likely to concentrate on real-time data handling than on API surface.
