"The (Many) Mistakes I Made in rkyv"
summary
Archive (rkyv) is a zero-copy deserialization framework that historically had unstable on-disk layouts and an opt-in fix that still broke cross-target compatibility; after 45 patch releases the 0.8 release finally makes repr(C) always required and wraps primitives to force endianness, fixing tier-two ARM surprises like 8-aligned 128-bit ints. The build removes a problematic blanket impl (replacing it with derive code) so the compiler now reports the actual trait bound failures, and the project drops hard public release estimates.
