A new patch release Crystal 1.20.1 fixes some regressions and disables Kernel TLS (added in 1.20.0), due to instability.

We released Crystal 1.19.2 to fix the request smuggling vulnerability (already fixed in 1.20.0) and a regression in Range#sample that could eventually lose randomness.

I’m working on handling OAuth token expiry as part of #ktistec Mastodon API support. Is my understanding that Mastodon issues OAuth tokens with no expiration correct?!?

Release v3.3.6 of Ktistec

This release is a maintenance update: a few bug fixes, a security mitigation worth paying attention to, and some performance improvements for users on slow connections.

It's worth updating to pick up the SSRF (Server-Side Request Forgery) mitigation.

Fixed

Prevent SSRF when dereferencing externally supplied IRIs.
Timeline entry no longer becomes stale when an announce is undone.
Correctly represent boosted posts on the home timeline in API clients.

Changed

Defer downloading of script files.
Defer loading of image, video, and audio attachments.
Move poll vote notification for voters into the outbox processor.

A new Crystal release is out for version 1.20.0

Highlights: `@[TargetFeature]` annotation, new process spawn API, support for kernel TLS and io_uring. The latter requires execution contexts which is now in the final preview.
