ReleasePort's take

Light signal

editorial:auto 4d

ReleasePort Layer 1 v0.114.0 removes the setrlimit/getrlimit wrappers on Linux to resolve a type‑mismatch bug and adds several new features across Claude, Laguna, Poolside, and response handling.

Why it matters: Fixes a critical runtime API wrapper defect on Linux; developers using those wrappers must update their code immediately. Feature additions expand model support and improve validation logic.
