Release:                 29

Check out the git tag OTP-29.0.1, and build a full OTP system including documentation. Apply one or more applications from this build as patches to your installation using the ‘otp_patch_apply’ tool. For information on install requirements, see descriptions for each application version below.

POTENTIAL INCOMPATIBILITIES

‘public_key’, Adhere to RFC 9525, and remove support for legacy fallback to check hostname against subject common name. Also improve error handling creating two separate errors for name constraint check for subject names and subject alternative names.

‘ssl’. Error handling is slightly changed to better reflect public_key behaviour.

Own Id: OTP-20130
Application(s): public_key, ssl
Related Id(s): [PR-11124], [CVE-2026-42790]
