Seastar announces that now that C艹23 is available, they will support C艹23 and C艹20 (dropping support for C艹17) in accordance with their support policy

Seastar, ScyllaDB, and C艹23

By Avi Kivity

From the article:

Seastar is an open-source (Apache 2.0 licensed) C艹 framework for I/O intensive asynchronous computing, using the thread-per-core model. Seastar underpins several high- performance distributed systems: ScyllaDB, Redpanda, and Ceph Crimson. Seastar source is available on github. As a C艹 framework, Seastar must choose which C艹 versions to support. The support policy is last-two-versions. That means that at any given time, the most recently released version as well as the previous one are supported, but earlier versions cannot be expected to work. This policy gives users of the framework three years to upgrade to the next C艹 edition while not constraining Seastar to ancient versions of the language.

Now that C艹23 has been ratified, Seastar now officially supports C艹20 and C艹23. The previously supported C艹17 is now no longer supported.
