From the SQLite patch notes: https://sqlite.org/releaselog/3_53_4.html

3.53.4
Fixes for problems in 3.53.0 (and 3.53.1, 3.53.2, and 3.53.3) mostly coming from AIs. See the check-in timeline for details.

Would you consider release a patch of SQLCipher? Among the fixes, there are some that could leave the database corrupted when using ATTACH https://sqlite.org/forum/info/4661175f3edecdf456f960b4d73013e7d7011680cce02f859b589a8cae160604
