For the complete documentation index, see https://buildwithfern.com/learn/llms.txt. ## 1.28.0 **`(feat):`** Inline documentation on XML-encoded (TwiML) types: each `field` carries its property description as a comment, and fluent child methods document the child type, the text parameter's description, and every attribute via `@option attributes` entries. ## 1.27.1 **`(fix):`** Cap generated request-wrapper filenames (`lib///types/*_request.rb`) at 100 characters, matching the existing cap on type filenames, so `gem build` no longer fails with `Gem::Package::TooLongFileName` for endpoints with long path-derived names (e.g. operations without an `operationId`). Over-long names are truncated with a short deterministic hash appended; the Ruby class name is unchanged.
