Okay, so two items on the long list of most fan-requested Overwatch features and changes are coming with the next update. First off, and this is a big one, is a complete revamp to the Highlight Reel system. So, instead of the game storing its own highlights that disappear as soon as you log off, now they'll last a lot longer. Plus, players will also be able to set bookmarks in-game to capture and then export their own highlights at even higher qualities than the settings they use to play!

Very cool. In addition to that the Loot Box system is also getting an update to drastically reduce the number of duplicates and increase the number of credits. Win, win.

Here's Blizzard's Jeff Kaplan talking about the changes.

Loot Box Updates

We always want the experience of opening an in-game loot box to feel exciting and rewarding, and in our latest patch we’re working to improve that experience in two key ways. First, we’re drastically reducing the amount of duplicates players will receive when opening loot boxes. Second, to compensate for this reduction of duplicate items, we’re also increasing the overall amount of credits players will receive from loot boxes. On average, players should be earning just as many credits, if not slightly more, from loot boxes than they did prior to these changes.

New Highlight Options

The game will continue to automatically generate highlights for you based on your recent gameplay. These auto-generated highlights—now categorized as "Today's Top 5"—will be surfaced on a daily basis and persist for a full 24 hours (or until the game client is patched, whichever happens first).
Players can now generate their own highlights! The ability to capture 12 seconds of your own gameplay has been added to the game, and can be bound to a single button of your choice (or a button per highlight slot) in the Options menu under “Request Highlight.” These player-generated highlights will be saved under a new section called “Recently Captured” and will persist until the game client is patched. Players can have up to 36 recently-captured highlights stored at one time.

With the above, players can now record any of their "Top 5" or "Recently Captured" highlights, exporting them as a video file to their gaming platform’s designated media library (on console) or directory (on PC). On PC, players will also have the option to select the quality at which these highlights are exported, supporting up to 4K at 60 FPS for Windows 8 or higher operating systems, and up to 1080p on Windows 7.

Both changes are now live on the Overwatch PTR.
