2.8.0 - 2017-12-07 - Centralized Local Package Store

Release Highlights

Quilt packages live in a centralized location on your machine

Quilt data packages are now available wherever you run Python. We recommend that users quilt push all local packages to the registry before upgrading. Further details on migration are here.

Faster builds with build cache

Quilt now caches build intermediates. So if you wish to update the README of a multi-gigabyte package, you can rebuild the entire package in one second.

Group-level build parameters

You can now specify build parameters (like transform) for all children of a group in one shot. The updated syntax and docs are here.

quilt.yml is like requirments.txt but for data

You can now express dependencies on multiple packages in a single file. Docs here.

Experimental: build a package from a GitHub repo

Quilt build now accepts GitHub URLs. If you use data stored on GitHub you can turn it into a Quilt package with quilt build.

2.7.1 - 2017-11-09 - Checks: unit tests for data packages

Building a package from a directory of input files now skips generating a build file. That speeds up the build process and makes it easier to change the package contents and rebuild.

2.5.1 - 2017-07-06 - Push Public Packages

This release includes support for paid plans on and is recommended for all individual and business-plan users. It adds a shortcut to push packages and make them public in a single command and improves documentation.
