# OSBuild Composer - Operating System Image Composition Services
## CHANGES WITH 11:
* The support for uploading VHD images to Azure is now available.
* AMI images are now produced in the vhdx format. This fixes
the issue that those images couldn't be previously booted in EC2.
* In version 10 the logs weren't saved when osbuild failed. This
is now fixed.
* The warnings when upgrading/removing the RPM package are now fixed.
Note that updating to version 11 still produces them because
the upgrade process runs also the scriptlets from version 10.
* The size calculation for Fedora 31 vhd images is fixed.
* The size field was removed from the tar assembler struct.
The field has actually never been supported in osbuild
and it doesn't make any sense.
* The minimal required version of osbuild is bumped to 12.
* This release also got big upgrades to the testing infrastructure,
more tests are run on a CI and they now run faster. Also, the unit
test coverage is improved.
