For reference, Erlang/OTP shipped 0 meaningful updates in the last 30 days and carries a velocity score of 5.0 out of 10 in 2026. The alternatives below are ranked the same way, so you're comparing real release momentum, not marketing claims.
About 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.
