OTP Update
summary
OTP 28 adds concrete language and runtime changes: comprehensions get relaxed generators and new strict generators (colon-arrow) plus zip combining with &/%&, the type system gains nominal types so Dialyzer can distinguish private vs public keys, and a new priority messages mechanism (priority aliases and priority option for monitors/broken links). The regex engine moves from PCRE to PCRE2, changing compiled-term representation. Runtime and library wins include scheduler task‑stealing fixes, GC and destructive‑update optimizations, TLS 1.3 data throughput improvements up to ~25%, SBOM per release (~6MB JSON), and 204 merged contributions.
