Well the new version (3.5.4) JUST came out right after my license expired. Here I thought I was buying lifetime upgrades, but it was lifetime use with one year of upgrades. So as soon as I buy a new license, we will upgrade it again.
If you hadn't noticed, we did upgrade it significantly from the version it was running before. There are several enhancements, such as the new post system, AJAX quick reply etc.
