• https://bsky.app/profile/tylerayoung.com/post/3mlsxbdmrw22e – Tyler Young highlights a heap of recent high-severity CVEs published against the typical Elixir + Phoenix web stack. Packages to check include cowboy < 2.15.0, cowlib < 2.16.1, plug < 1.19.2, bandit < 1.11.1, and decimal < 3.0.0.

• https://www.erlang.org/news/188 – OTP 29.0 released as a new major version. Highlights include unsafe function warnings, SSH daemon now defaults to disabled shell/exec services, SFTP no longer enabled by default, post-quantum hybrid key exchange as default in SSL, ANSI terminal support, Erlang doctest support, and xref now handles ignore_xref natively.

• https://bsky.app/profile/peterullrich.com/post/3mlmb7kwgoc2w – Peter Ullrich highlights performance improvements landing in Elixir — Base.valid(16|32|64)? is now 1.5-2.8x faster thanks to SWAR (SIMD Within A Register) optimizations.
• https://github.com/elixir-lang/elixir/pull/15357 – PR adding SWAR (SIMD Within A Register) versions of Base validations to Elixir. SWAR treats a CPU register like a small vector to check multiple bytes at once instead of one by one.
