Technical Support Plan
Because we have a large customer base that still depends on 3.x, we are very careful about how we manage the Product Life Cycle (PLC). Our strategy is to make all PLC dates relative to our estimation of the last 3.x release. When is the last release? It depends on when we reach full parity in 4.x, enabling us to move critical apps such as ArcGIS Online’s map viewer to 4.x. When we reassess our estimation of the final release date, PLC phase dates are updated accordingly.
Relative dates for each PLC phase are determined in the following manner:
- 3.x remains in "General Availability" until the last release of 3.x.
- 3.x moves into "Mature Support" after the last release, and lasts for 1 year.
- 3.x is retired 3 years after General Availability ends.
For more information about the above software support phases and what they entail, refer to the PLC.
Recent Update to the PLC
Version 3.x was scheduled to move into mature phase next month; July 2018. Based on the current status of the API, this was moved to July 2019, with the mature phase starting August 2019 and retirement in August 2022. As mentioned above, these dates will be revisited depending on progress made towards 3.x parity.
If you need further clarification on the above, please reach out to Technical Support through the normal channels.
