# Managing Packer Versions
|
||
|
|
|
||
|
|
Atlas does not automatically upgrade the version of Packer
|
||
|
|
used to run builds or compiles. This is intentional, as occasionally
|
||
|
|
there can be backwards incompatible changes made to Packer that cause templates to stop
|
||
|
|
building properly, or new versions that produce some other unexpected behavior.
|
||
|
|
|
||
|
|
All upgrades must be performed by a user, but Atlas will display a notice
|
||
|
|
above any builds run with out of date versions. We encourage the use
|
||
|
|
of the latest version when possible.
|
||
|
|
|

|
|
### Upgrading Packer
|
||
|
|
|
||
|
|
1. Go the Settings tab of a build configuration or application
|
||
|
|
1. Go to the "Packer Version" section and select the version you
|
||
|
|
wish to use
|
||
|
|
1. Review the changelog for that version and previous versions
|
||
|
|
1. Click the save button. At this point, future builds will use that
|
||
|
|
version
