[BCC all OP-TEE maintainers]

Hi OP-TEE maintainers & contributors,

OP-TEE version 4.11.0 is now scheduled for release on 2026-10-16. So, now is a good time to start testing the master branch across various platforms and report or fix any bugs.

The GitHub pull request for collecting Tested-by tags or any other comments is https://github.com/OP-TEE/optee_os/pull/8054.

We will create the release candidate tag 4.11.0-rc1 next Friday, October 2.
