# OSBuild Composer - Operating System Image Composition Services
## CHANGES WITH 10:
* The correct metadata_expire value is now passed to dnf. In the
past, this led to a lot of failed builds, because dnf has the
default expire time set to 48 hours, whereas the Fedora updates
repos have the expire time of 6 hours.
* A decision was made that the minimal Go version required for
building the project is 1.12. This is now enforced by the CI.
* The intermediate s3 object is now deleted after the upload to AWS
is finished. It has no value for users.
* The upload to AWS has now a bigger timeout. The current coronavirus
situation is affecting the AWS responsiveness in a negative way.
* The weldr API has better test coverage. In the process, several
bugs in sources and composes were fixed.
* Worker and jobqueue packages are receiving a big refactoring.
This is the prerequisite for having multiple job queues for building
images for different distributions and architectures.
* The image tests now boot the AWS images in the actual EC2.
