SourceMod 1.6.0 Release Notes

From AlliedModders Wiki
Jump to: navigation, search

SourceMod 1.6.0 is a major update with numerous under the hood improvements as well as some user-facing additions.

Overview for Admins

  • New Game Support - SourceMod, including base plugins, now supports Dota 2, Source SDK 2013 mods, Insurgency, Contagion, and Blade Symphony.
  • Updated gamedata for many games and mods.
  • Added support to create custom ban reasons for the basebans plugin (thanks Matthias "Dr. Greg House" Kollek). This uses a new configuration file named banreasons.txt
  • Many stability fixes.
  • Better performance.

Overview for Developers

  • Added an API for off-thread SQL transactions.
  • Added support for string literal concatenation (with new "..." operator) (thanks Peace-Maker).
  • Adjusted the OnClientSayCommand forwards to be more developer-friendly (thanks SystematicMania).
  • Too much to name here. For overview of all sourcepawn and SM extension API changes and additions, please see SourceMod_1.6.0_API_Changes

Compatibility Issues

In most cases, SourceMod 1.6.0 is fully backward compatible with the 1.5.x releases. The following are the few places where this is not the case.

Float comparisons

Plugins compiled against SM 1.6.0 that use float comparisons will throw errors upon load on older SM versions. This is due to a reworking of how these are handled to provide support for NaN vaules. Plugins compiled on < 1.5.x and earlier will continue to load fine on 1.6.0.

OnClientSayCommand and OnClientSayCommand_Post

Double-quotes are now stripped from the chat message, either quotes on both sides, or single double-quote on either side.

This removes the need for any manual stripping, but may affect some logic already in place. Since these forwards were still fairly new and still receiving fixes for issues in the 1.5.0 and 1.5.1 releases, we wanted to get this change in before use was more widespread.
