Changelog

February 13, 2026
February 13, 2026

1.0.0-rc86

(fix): Fix RuboCop style offenses in generated dynamic snippets. Generated Ruby snippets now use double-quoted strings, omit trailing semicolons, and drop empty parentheses on no-arg method calls. Also normalizes CRLF line endings to LF and adds RuboCop exclusions for snippet-only cops (FrozenStringLiteralComment, FirstHashElementIndentation) in the generated .rubocop.yml.

(fix): Change RuboCop Naming/VariableNumber enforced style from snake_case to normalcase in the generated .rubocop.yml. This eliminates false positives on API-derived identifiers that contain numbers (e.g., :recaptcha_v2, :sha256, :line1, :pkcs7) without requiring underscores before digit sequences.

(fix): Fix seed.yml Docker build command using incorrect package filter (@fern-api/fern-ruby-sdk instead of @fern-api/ruby-sdk).

(fix): Use %w[] syntax for arrays of simple strings in generated snippets, eliminating Style/WordArray RuboCop offenses.
