Erlang/OTP 29.0

Erlang/OTP 29.0, released May 13, 2026, introduces major features including native records as an experimental data structure, support for multi-valued comprehensions, post-quantum hybrid cryptography (x25519mlkem768) in SSL, and new security defaults that disable SSH shell and exec services. The release also adds compiler improvements, new language features like the is_integer/3 guard BIF, and multiple new compiler warnings to catch deprecated patterns and unsafe function calls, while removing 32-bit Windows support and repositioning the current directory in the code path for improved security.
