This notice is regarding the end of support for cflinuxfs2 buildpacks after 2019-08-31. As previously mentioned, Ubuntu has ended support for 14.04, and with that, support for cflinuxfs2 has also ended. Due to the need to migrate all applications from cflinuxfs2 to cflinuxfs3, we have continued to release cflinuxfs2 buildpacks while those migrations came to a conclusion. After August 31, 2019, all buildpack releases will be for cflinuxfs3 only.
If you are still in need of migrating your applications over to cflinuxfs3, the Stack Auditor tool can be of use.
Thanks,
Elliott Shanks
