3.7 Release
5/29/2020, 11:32:52 PM

Today's release brings a grab bag of valuable bugfixes, and a couple new features. I understand we didn't have a release two weeks ago as we should have according to our schedule, and that this release is a bit feature light. This is mostly due to my limited bandwidth the last month due to personal commitments, and several other regular contributors were busy with other real-life issues. Regardless, we're committed building the best cube platform we can, and I can assure you I'll be able to get back to spending more time on development soon.

New Features:

  • Updated filter syntax guide.
  • Added support for additional operators for more tag filtering, such as =, :, !=.
  • Added the ability to resize visual spoiler.

Bugfixes:

  • Fixed an issue with starting a sealed pool and building a draft deck for new cubes.
  • Fixed an issue where filtering by price crashed the UI.
  • Fixed filtering for all analytics.
  • Fixed an issue with populate analytics where it would not fetch Elo and prices correctly.
  • CSV export fixed to not output null rarity and color category.
  • Fixed an issue where imported colorless cards would crash pivot table.
  • Added better user feedback for invalid cube searches.
  • Fixed issue where pick by pick breakdown incorrectly reconstructed packs.

3.6 Release
5/2/2020, 12:40:37 AM

Today's update brings a lot of small changes including several fixes and updates for the newly revamped cube analytics. We're still halfway done with migrating our server to our new host, but I've done a lot of optimization to the configuration to reduce the amount of downtime. I've also implemented some new logging functionality for the live server, which will greatly help us in squashing those difficult to pin down bugs. As usual, please let me know what features, old or new, that you appreciate, and what features you would like to see in the future!

  • Card Modal links now go to a new tab.
  • Updated recommender to maintain the card's list positions when using a sort.

3.5 Release

This update comes with a huge upgrade in our server infrastructure. We've migrated from Digital Ocean to AWS, and so far everything is looking very smooth. The major advantages this brings are 100% seamless deployments, and auto-scaling - which means the site speed will not be impacted by the amount of traffic we're getting at any point in time.

As for the site changes, we have many very exciting new features to reveal. Cube Analysis has been completely overhauled (again), this time bringing in a few new tools including a machine learning powered card recommender.
