Beginning with Release 12.2: New releases will be annual and the version will be the last two digits of the release year. The release originally planned as 12.2.0.2 was released as 18, and the release originally planned as 12.2.0.3 will be release 19. For Lifetime Support purposes, Releases 18 and 19 will be under the 12.2 umbrella. Release 19 will be the last release ("_long term support_" release) for 12.2. Instead of Patch Sets, Patch Set Updates, and Database Bundle Patches, the new releases will be maintained with Updates and Revisions, so Patch Sets will no longer be shown in the roadmap for 12.2 and later. For more information see Update and Revisions for Database Proactive Patch Program (Doc ID 2285040.1).
