[!WARNING] The structure of scan exports in config.yml has changed! If you're currently exporting gamelist.xml files with scan.export_gamelist, migrate to scan.export.gamelist_xml: true

Highlights

Save sync engine

"Coming soon" no more! Third-party app developers will now be able to rely on RomM to keep save files in sync across devices and platforms. [#3137]

Devices (apps, handhelds, browsers) can choose to register themselves with the server, which uniquely identifies them with a token. The system tracks which device has the latest version of a save file, flags conflicts when two devices change the same save, and syncs in whichever way fits the device: on demand, via a watched folder, or through a scheduled background sync.

Play session tracking

Another one for the app developers: client devices submit batches of play sessions per device, recording when and how long games were played. Sessions track both the time window (start_time/end_time) and screen-on time (duration_ms), which may differ due to device suspension or back-grounding. [#3155]

Libretro thumbnails

The libretro thumbnail repository is now available as a first-class artwork source for region-correct box art (PAL/Europe, Japan, etc.). Matching is exact case-insensitive against the directory listing, so a ROM named "(Europe)" lands on the (Europe) artwork. The source is enabled by default, and you can set it's priority in your config.yml via the scan.priority.artwork list. [#3252]

Pegasus metadata export

You can now auto-export a Pegasus compatible metadata.pegasus.txt file, just like the existing gamelist.xml export. Enable it in your config.yml file by setting scan.export.pegasus to true, and it should appear in each platform folder (alongside your ROMs). [#3153]
