In May 2025, Peter Gomori contributed to the erlang/otp repository by updating documentation to clarify that atoms are encoded using UTF-8 by default in the External Term Format, aligning with changes introduced in Erlang/OTP 26.0. He focused on improving guidance for the term_to_binary/1,2 and term_to_iovec/1,2 functions, ensuring developers and downstream tooling have clear expectations around encoding behavior. Using Markdown and leveraging his documentation skills, Peter addressed potential ambiguities and improved onboarding for future contributors. While the work was limited in scope to a single feature, it demonstrated careful attention to technical accuracy and consistency across documentation.
