SyncroSim v3.1.30: Faster job handling, cleaner publishing, and cloud improvements

July 23, 2026


The latest beta release of SyncroSim (v3.1.30) is here, bringing three key updates: easier tracking for large, multi-part model runs, cleaner spatial output publishing, and several of SyncroSim Studio's improvements now available in SyncroSim Cloud.

Smarter handling of large runs

If you've run scenarios that split into many parallel jobs (for example, tiled raster processing), this release improves how those jobs are tracked and distributed:

  • Better split-job monitoring: partial job IDs are now tracked correctly, so progress on split/merge runs is easier to follow
  • Improved job distribution: when some stages of a run finish before others, SyncroSim now does a better job spreading remaining work across available scenarios instead of leaving some idle
  • Multiprocessing fix: transformers set to run on a single thread will now actually stay single-threaded, even when multiprocessing is enabled elsewhere in a run

Cleaner publishing of spatial outputs

Several changes improve how map outputs are published, particularly for large raster datasets:

  • Cloud Optimized GeoTIFF (COG) support: you can now choose to generate COGs directly during the publish step, which makes large rasters faster to load and view without needing to reprocess them afterward
  • Fewer unnecessary reprojections: publishing now avoids re-projecting maps that don't need it, cutting down on processing time and I/O
  • Safer publishing: SyncroSim now prevents a library from being published while a previous publish is still running, and will roll back cleanly if a publish fails partway through

Improvements to SyncroSim Cloud

To match the improvements made to Studio, we've made a few changes to SyncroSim Cloud:

  • Cloud Optimized GeoTIFF support: the biggest change, this significantly improves render time for map outputs
  • Finer default resolution: rasters now display with finer patterns by default
  • Small bug fixes: a handful of fixes improve map controls

Console and usability fixes

A few smaller changes make command-line workflows more flexible:

  • The --ver argument is now optional when adding a package via --add --package
  • Status bar and error messages in the package selection form now better reflect what's happening (for example, when a datasheet is missing because of an incompatible package)

Try it out

SyncroSim v3.1.30 is currently available as a beta-release. You can find the full technical changelog on GitHub. As always, questions and feedback are welcome on the SyncroSim Community Forum.
