What

The scrubber that strips secrets from error reports now recognises GitHub fine-grained personal access tokens, Square keys, Meta/Facebook long-lived tokens, Slack browser cookies (xoxc/xoxd) and OpenAI project and service-account keys. Applies to every crash and error report, with no flag.

Details
  • Slack, GitLab and GitHub patterns are now produced by a shared regex builder covering percent-encoded and URL-safe alphabets, fronted by cheap pre-scan checks so the expensive patterns only run when a candidate is present.
  • AWS key patterns now anchor on a non-alphanumeric boundary rather than a word boundary, catching keys embedded in longer strings.
  • The per-process cap on reports and its "already reported" marker moved from module-level variables onto an instance object.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
