+### OpenSSL Version Compatibility
+
+- MongooseIM 6.3.2+ requires OpenSSL 3.0 or newer to compile.
+- MongooseIM 6.3.1 and earlier support OpenSSL <3.0 but may have issues with SCRAM authentication when using OpenSSL 3.4.1+. See the [SCRAM hashing issue](../developers-guide/SCRAM-serialization.md#scram-hash-calculation-issue-in-mongooseim-410631) for details.
