GeoServer vs Erlang/OTP: at a glance
What is GeoServer?
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.
What is Erlang/OTP?
Three OTP branches move as one release train, and SSH and epmd carry the security load.
Erlang/OTP is patching three branches in lockstep — 29 as current, 28 and 27 as maintenance — with each fix set published as a trio within minutes of itself. The window is dominated by security work in the network-facing applications: OTP 29.0.4 carried six CVEs including an epmd denial-of-service mitigation, and the 4 August trio brought SSH into line with RFC 4253 by rejecting packets not aligned to the cipher block size, with a timing-safe packet-discard path for CBC ciphers. A regression in the previous patch that stopped epmd binding to localhost was fixed in the same trio.

GeoServer
0.0DEVOPS
GeoServer 3.0 breaks the monolith into extensions and adds DuckDB and GeoParquet paths.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Erlang/OTP
5.0DEVOPS
Three OTP branches move as one release train, and SSH and epmd carry the security load.
◆ Current state
Erlang/OTP is patching three branches in lockstep — 29 as current, 28 and 27 as maintenance — with each fix set published as a trio within minutes of itself. The window is dominated by security work in the network-facing applications: OTP 29.0.4 carried six CVEs including an epmd denial-of-service mitigation, and the 4 August trio brought SSH into line with RFC 4253 by rejecting packets not aligned to the cipher block size, with a timing-safe packet-discard path for CBC ciphers. A regression in the previous patch that stopped epmd binding to localhost was fixed in the same trio.
◆ Where it's heading
The maintenance pattern is unusually strict: 27, 28 and 29 receive the same trouble reports on the same day, so the effective support window is wide and sites on older majors are not being pushed forward by security pressure. Where the fixes land is consistent — ssh, ssl, crypto, public_key and erts account for nearly every changed application across these releases, which is the distribution epmd and the TLS/SSH stack impose on a distributed runtime. The CBC timing mitigation in particular is an old class of attack being closed properly rather than papered over.
◆ Prediction
Expect the next patch trio to follow the same shape — a small set of trouble reports applied to all three branches simultaneously — with ssh and ssl the most likely applications to change. Nothing in these entries indicates feature work landing on the patch branches; that stays on the next major.
