Platform API 0.3

Javier Romero <jromero@...>


New platform API 0.3 will be available after the release of lifecycle 0.7.0.

Platform API 0.3 comes with the following changes:

  1. Added support for project-metadata.toml. (#230)

  2. Added support for /lifecycle/creator. (#243)

  3. Added support for -process-type flag. (#260)

  4. [Breaking] Removal of the -helpers flag. (#259)


In general, platforms should ensure that they support the stated changes to be compliant with Platform API 0.3.


An update to the Tekton task will be available per issue #194.


Added support for Platform API 0.3

pack will be compatible with Platform API 0.3 although it will not yet take advantage of all the new features. (#509)

Dropping support of Platform API 0.1

The platform team aims to always provide support for n-1 of the platform API and buildpack API versions. Given that a new platform API version (0.3) is available, we found it reasonable to drop support for platform API 0.1. (#509)

For more detail on what the changes are between platform API 0.1 and 0.2 please refer to the prior notice.
