2026-08-18 08:00:00 -0400

We’re pleased to announce the immediate availability of SQLCipher 4.18.0. This is intended primarily as a maintenance release focused on dependency updates, cleanup, and bug fixes, along with a few minor improvements. However, it also includes a significant update to SQLCipher for Android which adds support for Room 3.

SQLCipher Changes

• Updates the upstream SQLite baseline to the latest patch release 3.53.4
• Avoids allocating memory on Windows during log writes which could cause a crash on Windows under non-default log settings with PRAGMA cipher_memory_security = ON
• Fixes “relocation truncated to fit” error for optimized GCC builds
• Adds comments clarifying intent of crypto_openssl.c
• Other miscellaneous fixes and general improvements

SQLCipher for Android and Room 3 Support

SQLCipher for Android adds support for Room 3 in addition to earlier versions of Room. Alongside that improvement, the compileSdk version is now 37.
