Language Environment® for OS/390® & VM
Release history

IBM's® current policy is to provide maintenance for each release of OS/390 for three years following its general availability (GA) date. However, in recognition of the workload many customers had for Year 2000 readiness, IBM has deviated from this service policy for OS/390 Version 1 Releases 1, 2, and 3, and Version 2 Release 4. These OS/390 releases will be considered current until at least 31 January 2001, with IBM providing maintenance during this period.

Notes:
  1. IBM intends to provide at least twelve months notice prior to the withdrawal of service for any version or release of OS/390.
  2. Service on the last release of a version might be extended beyond the intended three year period.
