Important:

If you see this page when you first open the "Source SDK" (AppID 211) launcher, please note that the standalone Source SDK tool/launcher is no longer updated, and does not support Source 2013 and Team Fortress 2 branch games.
The deprecated Source SDK tools are provided to create content-based mods for Source 2009 or earlier, and to obtain source code & create or maintain legacy mods built on Source SDK Base 2006 and Source SDK Base 2007.

Many Source 2013 and Team Fortress 2 branch games are usually shipped with Source SDK preinstalled, located in the \bin folder. To launch the SDK applications (Hammer, HLMV, etc...) manually on Source 2013 games, see the SDK Installation - Source 2013 (SteamPipe) & TF2 branch section for a list of applications and their executables.

Note:The latest release note on Steam News page is no longer updated. Instead release notes and changes below are copied from source-sdk-2013 GitHub Commits history. It is also recommended that you visit Source SDK 2013 GitHub page and view recent changes there, as this page may not be up to date.

+=== Multiplayer ({{tf2branch|1}}) ===
-** Fixed a client crash when switching between windowed-mode and fullscreen for {{mac|4}} and {{linux|4}} clients
+; TF2 fixes{{colon}}
-** Added experimental {{code|cpu_frequency_monitoring}} convar to detect thermal throttling. If you have performance problems on Windows, add {{code|"+cpu_frequency_monitoring 2"}} to the command line to see if CPU thermal throttling is an issue. If the displayed CPU frequency percentage drops below about 80-85% then you may have a problem with your CPU slowing down due to overheating. If it drops below 50-55% then you may have a serious problem. CPU overheating can be caused by overclocking, insufficient cooling, insufficient airflow, failing or dirty fans, or other causes.
