Marcel drops Ruby 2.3 and resets canonical MIME types, while Jean Boussier trims needless Array#flatten calls out of Reflection.

Marcel finally ships 2.0.0, a major release that requires Ruby 3.3 or newer and changes the canonical type returned for some inputs, so scan the changelog before you upgrade [1]. The refresh to the Apache Tika 4.0.0 MIME database [2] lands in 2.1.0, which adds detection for Android binary XML and fixes timestamped-data recognition [3]. Meanwhile, Solid Queue closes a zombie-process hole: processes whose heartbeats keep failing are now stopped and replaced instead of running unregistered forever [4]. The async supervisor also survives worker-thread deaths even when releasing claimed jobs fails [5]. Active Resource fixes a circular require warning in its railtie [6] and adds support for the proposed HTTP QUERY method [7]. And Rails core gets a micro-optimization: Reflection#extensions avoids needless Array#flatten calls, which forces allocation of an expensive identity hash on nested arrays [8].
