Release 1.6.3

Version bump and changelog for the 1.6.3 sync. All eight crates ship the
same version, so the crates with no functional change this cycle say so
rather than carrying an empty section.

 # Changelog
 
+## [1.6.3] — 2026-08-10
+
+### Changed
+
+- **Housekeeping only — nothing about how a drive is unlocked has changed.** The
+  cryptography and compression crates this crate builds on were moved to their
+  current releases and brought into line with the versions the rest of freemkv
+  uses, so one version of each is built instead of two.
+
 ## [1.6.2] — 2026-08-08
 
 Version sync with the workspace. No functional change in this crate.
