Scope

This End-of-Life Policy ("EOL Policy") is effective as of November 17, 2017 and supersedes all its previous versions.

This EOL Policy applies to all Appeon products.  It defines the lifecycle of each product and the types of technical support available during this lifecycle.  Appeon reserves the right to modify the EOL Policy upon 180 days written notice posted to the Appeon Website. As such, it is recommended that you periodically check this page for revisions.

Product Versioning

Appeon makes versions of the Software Programs as follows:

  • Major Versions
  • Revisions
  • LTS or Long-Term Support Versions
  • MRs or Maintenance Releases
  • EBFs or Emergency Bug Fixes

Major Versions are versions of the Software Programs that contain substantial new features.  All Major Versions go through Appeon’s full QA process, and most Major Versions go through some sort of beta testing (often times private beta programs).  You can identify a Major Version by a change in the year numbering (e.g. PowerBuilder 2017→ PowerBuilder 2018).

Revisions are essentially minor versions of the Software Programs.  Specifically, a Revision is a Major Version that has been revised to include some minor new features and usually incorporate the absolute latest bug fixes (at the time of the Revision’s GA).  All Revisions go through Appeon’s full QA process, but generally they do not go through any beta testing since these are relatively low-risk versions.  You can identify a Revision by the acronym “R” appended to the Major Version numbering (e.g. PowerBuilder 2017 R2).  The introduction of a Revision for a Major Version does not extend the EOMM date of that Major Version.

LTS Versions are Major Versions or Revisions that are eligible for long-term support. Only selected Major Versions or Revisions will receive the LTS designation, and usually only after being on the market for a period of time to ensure a relatively high-degree of reliability. LTS Versions are eligible for Standard Support[1] for at least 36 months or for a minimum period of 12 months after a replacement LTS version of the Software Program is available, whichever is greater.  LTS Versions are recommended for users that prefer to upgrade at a slower pace and are not in urgent need of the planned product roadmap features.

MRs are a collection of bugs fixes for a Major Version or Revision – MRs contain no new features.  All MRs go through Appeon’s full QA process.  You can identify a MR by reading the accompanying ReadMe document and the fact that it requires a Major Version or Revision (as applicable) to be already installed.  In general, it is a good practice to stay up-to-date on MRs since they are intended to improve the reliability of the Software Programs and are generally very low risk.

EBFs are a patch for a Major Version or Revision that fixes or works around an emergency bug– EBFs contain no new features.  EBFs do NOT go through Appeon’s full QA process, which makes them relatively risky to apply.  You can identify an EBF by reading the accompanying ReadMe document and the fact that it requires a Major Version or Revision (as applicable) to be already installed.  Appeon strongly discourages EBFs and all use of EBFs shall be at your own sole risk.

General End of Life Policy

Each version of the Software Program will be replaced with a newer future version unless the Software Program is otherwise discontinued.  Future Major Versions may discontinue or deprecate particular features or stop providing support for a particular software environment configuration for a variety of reasons, including but not limited to technology obsolescence, discontinued support from a third-party vendor, or availability of a replacement feature.  A discontinued feature means a feature that has been removed from the Software Program.  A deprecated feature means a feature that is still contained in the Software Program (for backwards compatibility) but is no longer being enhanced or eligible for Standard Support.

This EOL Policy builds upon Appeon’s Standard Support policy , setting forth the timeframes Appeon has currently planned to provide maintenance and technical support for the various versions of its products.  Premium Support[2], which is offered at an additional cost, offers assistance with technical issues that are out of the scope of the Standard Support (e.g. issues with deprecated features, general troubleshooting, etc.) or occur after the product EOMM but before EOL. To open a Standard Support or Premium Support ticket please refer to https://www.appeon.com/developers/get-help.html.

The End of Life timeline is set forth in Figure 1 and Figure 2 below.

Acronyms used in the above figures are explained here for reference:


  GA - General Availability             
  LTS - Long-Term Support
  EOMM - End of Mainstream Maintenance
  EOL - End of Life


Product Fixes

After the General Availability of the Software Program, Appeon will provide product fixes in accordance with the Appeon Standard Support policy. Usually, Appeon provides product fixes in the form of MRs that are released on a periodic scheduled basis, but under rare circumstances Appeon may provide product fixes as EBFs to a specific or select group of Appeon customers. If a Major Version of the Software Program is not designated by Appeon as a LTS version of the Software Program, Appeon will provide product fixes for a period of 12 months after introduction of the next Major Version of such Software Program. If a Major Version or Revision is designated by Appeon as a LTS version of the Software Program, Appeon will provide product fixes for at least 36 months or for a minimum period of 12 months after a replacement LTS version of the Software Program is available, whichever is greater.

All MRs and EBFs are provided according to the Standard Support policy. As such, you may be required to upgrade to a particular MR level and/or Revision before applying a subsequent MR or EBF, which is consistent with Appeon’s Standard Support policy.

End-of-Life (EOL) Notice

An EOL Notice marks the beginning of the end of the lifecycle for a particular version of the Supported Programs. Appeon will publish the EOL Notice to the Appeon Website at least 6 months prior to the End of Mainstream Maintenance date. We recommend you periodically check the Appeon Website for such EOL notices.

End of Mainstream Maintenance (EOMM)​

End of Mainstream Maintenance (“EOMM”) means the date Appeon will cease providing Standard Support for the applicable version of the Software Programs. Prior to the End of Mainstream Maintenancedate, Appeon will actively provide maintenance forthe Software Version, which includes emergency bug fixes (“EBF”), workarounds, and maintenance releases (“MR”). When a version reaches the EOMM date, it will, however, no longer be supported by engineering.  In other words, Appeon will no longer provide any EBFs or MRs for any software defects of the applicable software version.

End of Life

End of Life (“EOL”) means the date when all technical support ceases for a discontinued version of the Software Programs. Generally, EOL occurs 12 months after EOMM.

[1] Standard Support means the standard maintenance and support to be provided by Appeon or its designated agents as set forth in the Appeon Standard Support Plan Terms and Conditions.

[2] Premium Support means paid technical support provided to Appeon customers that is in addition to the Standard Support.
