from a postmortem of the 1.5 M2 release, written by one of the PM coders of the 1.5 project.Pyro wrote:...Though I'd like to know which plugins were supposedly broken by magma's update.
"Unfortunately, one of the downsides of the Myth II update version 1.4 was that it broke a number of these existing plugins, rendering them unplayable. While not all plugins were affected, since only a subset relied on the functionality that was changed in version 1.4, it was still a significant number and thus something needed to be done about it. In addition, Myth II version 1.4 added a new option - "vTFL gameplay" - which simulated the gameplay of the original Myth: The Fallen Lords within Myth II. However, the "vTFL gameplay" code was added without having access to the original Myth: TFL code that was being simulated - so it was not completely accurate, and even worse: some of those gameplay changes ended up slipping into regular Myth II - something that was not intended to happen. "
and
"With version 1.5, we wanted to revert the gameplay and plugin compatibility of the game to be very close to Myth II 1.3 - Bungie's last update, while still keeping most of the features that made 1.4 great. So we started with the virgin Myth II 1.3 codebase and added, selectively, features from 1.4 that we felt were worth keeping, while leaving the bad ones out, or recoding them in a better way. Since by that time, we were able to get access to original Myth: TFL code, the "vTFL gameplay" feature was completely redone using the actual code from Myth: TFL - and unlike 1.4's attempt - it was cleanly separated from regular Myth II gameplay, so that normal Myth II gameplay would be left unaltered.
In the end, this effort was very successful, as plugins that were unplayable with 1.4 now worked perfectly with Myth II 1.5, and the gameplay of Myth II 1.5 was very similar to that of Myth II 1.3 (differing only in the lack of some of the bugs that were present in Myth II 1.3). "
