Changes

Kernel TLS

Support for Kernel TLS was introduced in 1.20.0 but it showed issues in production. Some have been fixed (#16888) but there are still some problems so it was disabled by default (#16897).

You can opt-in to Kernel TLS by adding the ENABLE_KTLS option:

ssl_context.add_options(OpenSSL::SSL::Options::ENABLE_KTLS)

Thanks, @ysbaddaden

Randomness in Range#sample

This patch release fixes a regression in Range#sample (#16853) that could eventually lose randomness.

Thanks, @ysbaddaden
