- The formulae.brew.sh env-config table was hard to interpret: unset and explicitly-set-to-default runs were merged as "default events", nothing showed what a variable's default was and variables brew exports itself (`HOMEBREW_UPDATE_TO_TAG` in `cmd/update.sh`, `HOMEBREW_EDITOR`/`HOMEBREW_DISPLAY` etc. copied from the user environment in `bin/brew`) dominated the chart as fake user configuration. - Record `HOMEBREW_USER_SET_VARS` at `bin/brew` startup, after `brew.env` files load but before any exports, so sampling and `brew config` can tell deliberate configuration apart; sub-brews inherit the list. - Replace the `env_config_non_default` tag with a single `env_config_state` tag (`unset`/`default`/`non_default`) computed from user-set values only. - Compute previously `default_text`-only defaults so explicitly-set default values are ignored everywhere: `HOMEBREW_AUTO_UPDATE_SECS` (mirroring `brew.sh`), `HOMEBREW_FORBID_PACKAGES_FROM_PATHS` (now `boolean: :set`, matching its accessor), `HOMEBREW_PIP_INDEX_URL` and `HOMEBREW_SSH_CONFIG_PATH`; generated accessors and `non_default_variable?` call callable defaults and treat blank booleans as unset like their accessors. - `brew config` now only prints user-set non-default variables and `Resource#determine_url_mirrors` only rewrites PyPI URLs for non-default `$HOMEBREW_PIP_INDEX_URL` values. - Sanitise `formula-analytics` results: only current variables and valid states are accepted and the query requires the new tag, which drops the contaminated data already collected. - Stop excluding CI events from `command_run_options`: CI users are normal users so CI-only usage should stay visible. - Output `non_default_count`, `set_default_count`, `unset_count` and `default_value` per variable in JSON, using the human `default_text` summary for varying defaults via `EnvConfig.default_description`, now shared with the manpage.

🤝 Contributing
We'd love you to join us and >10,000 others by contributing to Homebrew!
First, please read our Contribution Guide and Code of Conduct.
A good starting point for contributing is:
brew tap --force homebrew/coreorbrew tap --force homebrew/cask(depending on whether you'd rather work on formulae or casks)- perform a strict audit on a package you use e.g.
brew audit --strict ffmpegfor FFmpeg - if no warnings, run
brew audit --strictto run on all packages and pick one to fix - read through the warnings and fix them until
brew audit --strict <package>shows no results - submit a pull request with your fixes
Alternatively, for something more substantial, check out one of the open issues in Homebrew/brew, Homebrew/homebrew-core or Homebrew/homebrew-cask.
If you've had inspiration for a new feature or bug fix: we don't need you to open an issue first, just open a pull request with your implementation and we'll review it.
Good luck!
