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.
What is Speakeasy?
Speakeasy stopped inventorying MCP servers and started adjudicating them.
Speakeasy ships near-daily platform releases with unusually legible notes — each headline states what changed for a user, not a version number. The current one turns the Shadow MCP page into a single review surface where every server carries an approval state and an automatically gathered evidence dossier: publisher, requested scopes, declared capabilities, maintenance signals, and whether internal teams already talk to it. Decisions enforce on record. Around it, the assistant surfaces have been consolidating: one detail panel for configuration and observation, exact session totals, and canonical identities folding a person's work and personal AI accounts together.
Erlang/OTP vs Speakeasy: editorial side-by-side
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.
Speakeasy
10.0DEVOPS
Speakeasy stopped inventorying MCP servers and started adjudicating them.
◆ Current state
Speakeasy ships near-daily platform releases with unusually legible notes — each headline states what changed for a user, not a version number. The current one turns the Shadow MCP page into a single review surface where every server carries an approval state and an automatically gathered evidence dossier: publisher, requested scopes, declared capabilities, maintenance signals, and whether internal teams already talk to it. Decisions enforce on record. Around it, the assistant surfaces have been consolidating: one detail panel for configuration and observation, exact session totals, and canonical identities folding a person's work and personal AI accounts together.
◆ Where it's heading
The arc runs observe, then intercept, now adjudicate. Earlier releases catalogued spend and inventoried shadow MCP servers; the LiteLLM integration moved enforcement to the proxy so a violating prompt dies before inference; this release supplies the judgment layer, doing the research an approver would otherwise do by hand. The supporting work points the same way — prompt-injection scanning of captured skill manifests, risk policies that pause instead of being deleted, identity resolution that reports a whole person rather than an account. Each is a piece a control plane needs before its verdicts can be trusted.
◆ Prediction
Expect approval state to start gating traffic rather than only recording a decision, and the evidence dossier to extend from MCP servers to the skills and assistants already being captured. The rollout flag on the approval workflow suggests general availability is the next step rather than new capability.
