SQL Relay 1.8.0
This release mainly lays the groundwork for some future features, including a generic import/export framework. Some notable progress was also made on the JDBC driver, though it's still not finished. The most significant (finshed) new feature is an aes128 password encryption module.
There are some bugfixes as well. A long-standing issue with postgresql that could cause results from multiple open cursors to get confused has been resolved. A subtle error that could cause counting of bind variables on the client-side to hang has been fixed. A long-standing, but apparently obscure, issue that could cause tables from other MySQL schemas to be included in a "show tables" command has been fixed. As well as various other issues.
Full ChangeLog follows:
unattended tests
added sqlrresultsetdomnode class to c++ client API
