For all node operators - a hard fork for testnet to support the 3.3 release is planned for block 109280, which is roughly Nov 5th ~1800 UTC.
https://github.com/stacks-network/stacks-core/releases/tag/3.3.0.0.0

docker images: https://hub.docker.com/layers/blockstack/stacks-core/3.3.0.0.0/images/sha256-440fde0d3ebd613a99fece9f34a111bb819b8d4603aed4d4f4ed2bd2a45384e1

and the announcement: https://groups.google.com/a/stacks.org/g/announce/c/lB2QLL9T29U

If running a node, this is a required upgrade, else a sync from genesis or a restore from an archive will be required.
