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 GeoServer and OpenTripPlanner — release velocity, themes, recent moves, and the top alternatives to consider.
GeoServer 3.0 breaks the monolith into extensions and adds DuckDB and GeoParquet paths.
GeoServer cut 3.0.0 in June after maintaining 2.27.x and 2.28.x in parallel through the first half of the year. The major release is structural rather than feature-led: KML, WCS 1.0 and 1.1 move out to extensions, arcgrid and worldimage become plugins, WMS 1.1 and 1.3 are split, WMS is made independent of WFS, and H2 is removed from the product and the test suite entirely. New data paths arrive as community modules — a DuckDB datastore and single-file GeoParquet upload via REST — and OIDC is promoted from community module to supported extension.
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 directions are legible. The core is being reduced to what every deployment needs, with everything else pushed to extensions and plugins, which is the standard fix for a server that has accumulated two decades of optional protocol support. Separately, the OGC API surface is where the ongoing functional work is: Processes gained envelope inputs, multiple raw responses, pagination, correct incomplete-execution errors and an Echo process across these releases, while the older WFS/WMS work is mostly bug fixing. The 2.28.x line continues to receive the same fixes, so the branches have not diverged in behaviour yet.
Expect the DuckDB and GeoParquet modules to be the ones promoted next, following the path OIDC just took from community to extension, and expect 3.0.x to spend its early point releases on fallout from the H2 removal and the extension split. Continued OGC API Processes work is the safest bet in the functional roadmap.

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.
