[Simon Ser]

Hi all,

Here is the release schedule for Weston 11.0, the next major version:

- Alpha: August 9th, in 2 weeks
- Beta: August 23rd
- RC1: September 6th
- First possible release: September 13th

Package maintainers are encouraged to pick up the pre-releases to make
sure packaging can be tested (and fixed) before the stable release.

Let me know if there's something in particular you want merged for 11.0.

Thanks,

Simon
