Glad to announce D 2.085.0, ♥ to the 49 contributors.

This release comes with context-aware assertion messages, lower GC
memory usage, a precise GC, support to link custom GCs, lots of
Objective-C improvements¹, and toolchainRequirements for dub.
This release also ended official support for OSX-32.
