May I ask what makes this a major release? I.e., what are the the breaking changes compared to v2?

[robjtede]

Breaking changes documented here: https://github.com/actix/actix-web/blob/master/MIGRATION.md. Also the time crate was updated and causes breaking changes to things like setting cookie expiry times.

@robjtede May want to add #1464 as well

Hello everyone. Is it possible to release a new beta version with the memory leaks bug fixed? I want to migrate my project from actix 1.0 to 3.0, but the memory leak issue is the only thing that stops me (other release blockers are not).

@JohnTitor How about releasing a new beta version?

[JohnTitor]

@attliaLin Sounds good, will do.

When is the stable release of v3 coming?

[JohnTitor]

We should migrate new versions of actix-{codec,utils}, at least: #1634
