Game Recording
Improvements to drag and scroll behaviors when finalizing the beginning and end of a clip
No longer warp the play head to the beginning/end of a clip when setting the beginning/end of a clip via the UI buttons
Fixed a bug where using the hotkey to add a user marker would drop the marker at the wrong location
Increase the minimum background recording time to 15 minutes, to give the user time to edit recent clips before the recorded video ages out
Added a warning to the user if game recording has been turned off to prioritize broadcasting
Ignore user marker shortcut key if game recording is disabled
Improved reliability of saving/renaming of .m4s video segment files when antivirus software locks the files temporarily
Added the ability to save a specific frame of a video as a steam screenshot
Improved default naming of clip files to improve readability and sortability. Steam will also scan game state descriptions to apply to default clip filename, if available
Fixed an exception thrown if the user canceled a clip save in the file picker dialog
Updated message displayed when there is no recent other session where the user can send a clip

I was actually using snipping tool for this as it was missing. Being able to get a screenshot of something after the fact is a nice feature.
