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 RaspAP and Erlang/OTP — release velocity, themes, recent moves, and the top alternatives to consider.
A one-maintainer Pi hotspot tool that picked up a second pair of hands and a UI overhaul.
RaspAP ships small releases often — ten versions since late October 2025, most of them a handful of merged pull requests. The substance changed around 3.5.3: a second contributor started landing structural work, refactoring the JavaScript and CSS, simplifying the dashboard, adding a client interface selector, DHCP config overview and reconnect dialog. Before that the feed is almost entirely locale updates and one-line fixes from the project lead.
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.

Two threads run in parallel. One is keeping pace with hardware and distributions — 802.11ax/be support, Kali detection, Raspberry Pi Imager 2.x integration — which keeps the tool installable on current setups. The other is a genuine interface rework that arrived with the new contributor and has continued across three releases. The release notes are raw pull-request lists with no narrative, so the shape has to be read from PR titles rather than any summary the project writes.
Expect the interface refactor to keep producing dashboard and configuration screens, and continued installer work as new Pi OS and Imager versions land. The entries give no indication of a major version change.

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.
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.
