Version 2.13 was an upgrade to the compiler only. Version 2.15 is functionally identical to version 2.13, but it comes with revised libraries. You will never see version 2.13 in the stores, only on the net. You will only see version 2.15 in the stores, not on the net. However, I have posted the libraries supplied with 2.15 to .binaries.mac, and you can get the two disk full update to version 2.15 by sending some $ to THINK. --Rich
