SQLEditor 1.3.6 has now been available for about a week and so far it looks good. 1.3.6 was mainly released to fix bugs found in 1.3.x releases and to add in a few important features that had been widely requested.
MySQL auto increment was probably the main improvement, but there were also some more changes to fix the connection issues.
One slight change that probably won’t get noticed at all if it works is that the page that version updates are directed to has changed. The url is now a special page rather than simply the product page. This should make it easier to download updates. (I’ve been looking into sparkle and friends for use in some later version)
I guess the upgrade advice is that 1.3.6 is recommended for all users, but if your current version is satisfactory then no need to upgrade.
