As previously announced, 2017.1 on VSI OpenVMS 8.4-1H1 is the final major version of Caché and Ensemble. 2017.1 will not be available for VSI OpenVMS versions beyond 8.4-1H1.
Maintenance releases of 2017.1 on VSI OpenVMS may be announced but only to deliver critical corrections. 2017.1 on VSI OpenVMS will be the Minimum Supported Version from July 1, 2019 through December 31, 2020. After December 31, 2020, no further maintenance releases will be made available.
As stated on the Minimum Supported Version page, Technical Assistance will continue to be available for all products and versions, regardless of release age. Ad hoc corrections for releases older than the Minimum Support Version will be made on a “best effort” basis but cannot be guaranteed.
