Notes

An executive decision has been made on versioning going forward. Instead of publishing pre-releases on 4.4.0 forever, this is now 4.5.0. Patch releases on the 4.5 series will be released as time goes on. You should consider the 4.5.x series unstable. All odd numbered versions (4.5, 4.7, 4.9) will be unstable. When a stable version is released, it will be even (e.g., 4.6.0, 4.8.0, 6.0.0).

The reason for this change is simple. The TShock automatic update system does not display updates for pre-releases. Unfortunately, it is quite useless to have an automatic updater when you don't use it. Polishing 4.4.0 has been time consuming, and therefore, we haven't been able to push a stable version for a while. Because of this, the lack of an automatic update function means that people are left in the dark about important updates. This is a problem.

We are planning on publishing updates more frequently to resolve stability issues and improve the system. Unfortunately, it's just taking a bit longer than usual.

To upgrade, simply overwrite all applicable files in your existing server folder. TShock releases are designed so that you can upgrade by copying all files over and clicking "yes" to overwrite any duplicates. All existing world and character and database data will be saved. Please make a backup copy of your world file and your TShock configuration before installing.
