Active4D v7.0r7, the ultimate web development environment for 4D, has just been released. This is mainly a bug fix release. If you are using the NTK shell and v7, you should upgrade to this version ASAP. There was a bug that could cause a crash if a request exceeded the maximum request size.
Thinking of upgrading to v7? Active4D v6.4 licenses that are up to date do not need to purchase an upgrade, but a new license key must be requested via email. Upgrades from previous versions can be purchased online.
