The blog post 1.99.0 pre-release testing | Inside Rust Blog only appeared in my RSS feed today.

Was it a problem with the RSS feed or was the blog post only posted today?

Same

Looks like that accidentally skipped publication due to other CI changes: #t-release > 1.99.0 @ :speech_balloon:

期待这次更新,有什么博主讲解推荐么?:heart:Rust

Hmmm, I'm a bit surprised Vec::from_/into_parts doesn't mention any interaction with from_/into_raw_parts.

Was that brought up on the tracking issue, if any?
