PubNub SDK EOL Policy

Effective March 2018

Laymen TL;DR

When an SDK Major or Minor version is released PubNub will stop supporting the last Major. The Minor version of the release twelve months later. For example, if the Major version 3.0.X is released on April 1, 2018, support for version 2.8.X would end on April 1, 2019. If version 3.2.X is released on May 1, 2018, we would stop supporting version 3.0.X on May 1, 2019.

Official Policy

To ensure the delivery of innovative and cost-effective products, PubNub will periodically discontinue specific SDKs, APIs, Tools, Services, and features. At PubNub's sole discretion, such products or services may be discontinued regardless of the delivery method, including on-premises software, hardware, and cloud services. This policy describes the intended communication and transition plans for discontinued products and versions and provides information required to plan for migration to replacement technologies. Any questions arising in the interpretation of this policy or the application of this Policy shall be as determined by PubNub at its sole discretion. Any conflict between this Policy and the terms of support shall be controlled by the provisions of this Policy.

Releases

Major (Main) Release

Major releases encompass new products, major architecture changes, major user interface (UI) changes, significant new features or capabilities/functionality additions, new solutions, and substantial innovation.

Minor Release

Minor releases include updates or enhancements/features to existing products, moderate administration or UI changes, and major bug fixes.

Update (Patch) Release

Update releases incorporate minor bug fixes, security fixes, and service packs. Update releases are typically incorporated into the next Minor Software release.

The Software product version numbering scheme is defined as follows.

(Major). (Minor). (Update)

Example: 3.1.4 Where Major release is 3, Minor release is 1, Update release is 4

SDKs

PubNub will make commercially reasonable efforts to adhere to the following guidelines:

1. The End of Life (EOL) Period for a Major.
2. Minor Software release, "N," starts when the N+2 release becomes Generally Available.

The maximum total support life of a Software release is the lesser of:

1. three (3) years from the date it first became Generally Available or
2. one (1) year after the N+2 Major. The Minor version becomes Generally Available.

Example 1: SDKs with Major. Minor version of 3.9.X will be marked as EOL once version 4.1.X becomes released.

Example 2: SDKs with the Minor version of 4.1.X will be marked as EOL once version 4.3.X is released.

Customers with paid support plans will receive support as described above. During this time, critical bug fixes may be made available but for access to new features or optimizations released in a later version, an upgrade will be required.

Customers creating standard support issues using our free service may be asked to upgrade to the currently supported SDK version before receiving further support.

In all cases, no further feature development will be done on the SDKs after the EOL date has been reached.

• The platform it operates on is supported by our original equipment manufacturer (OEM) technology partner (where applicable); and

• Technical support for issue resolution will be provided on a commercially reasonable basis; and Custom Software Support could be added at an additional cost:

  • Product Enhancement Requests (PER)
  • Patches, Updated, Hotfixes or Engineering-related support
  • New Operating System support
  • SLA commitments related to defects in the supported product
