Next Release Notes Draft

DRAFT RELEASE NOTES — Introduction to Go 1.27

Go 1.27 is not yet released. These are work-in-progress release notes. Go 1.27 is expected to be released in August 2026.

Standard library

Minor changes to the library

`net/http`

HTTP/2 server now accepts client priority signals, as defined in RFC 9218, allowing it to prioritize serving HTTP/2 streams with higher priority. If the old behavior is preferred, where streams are served in a round-robin manner regardless of priority, Server.DisableClientPriority can be set to true.

`unicode`

The unicode package and associated support throughout the system has been upgraded from Unicode 15 to Unicode 17. See the Unicode 16.0.0 and Unicode 17.0.0 release notes for information about the changes.
