For the complete documentation index, see https://buildwithfern.com/learn/llms.txt. ## 1.1.6 **`(chore):`** Pretty-print generated wiremock-mappings.json with 2-space indentation to reduce diff sizes on subsequent SDK generations. ## 1.1.5 **`(fix):`** Prevent `additional_headers` in request options from overriding SDK-set headers such as Authorization, Content-Type, and SDK metadata. Headers set by the SDK or the API definition are now protected (case-insensitively) and silently filtered from additional\_headers. **`(fix):`** Reject HTTP URLs for non-localhost hosts. Requests to `http://` URLs now raise `ArgumentError` unless the host is localhost, 127.0.0.1, or \[::1], preventing accidental transmission of authentication credentials in plaintext. **`(fix):`** Explicitly set `verify_mode = OpenSSL::SSL::VERIFY_PEER` on HTTPS connections. This was already the Ruby default but is now stated in code to satisfy security audits.
