Xojo 2021 Release 1 updates its SQLite engine to 3.34.1 (from 3.33.0). This release does not have a lot of new features, but there are a few notable ones that you might find useful.
First, the performance of WAL mode (write-ahead logging) is improved when there are lots of connections all accessing the same database file. This ought to provide noticeable improvements for web apps that use SQLite databases.
A minor change is that the “substr()” SQL function can now also be called “substring()” for compatibility with SQL Server.
There are a few other performance improvements as well. Visit the SQLite site to read the official release notes.
