What’s shutting down in November 2026
6 things are scheduled to be taken away in November 2026. Closest first — each links to the vendor’s own announcement.
Runtime →44 days
Microsoft Azure Azure Databricks Runtime 10.4 LTS reaches end of life; clusters and jobs must move to a supported Databricks Runtime version
OS →44 days
Alpine Linux The Alpine Linux 3.21 release branch reaches end of support (end of life) on November 1, 2026. After that date the 3.21 branch stops receiving security fixes and package updates, so container images built on the `alpine:3.21` base tag no longer get patched.
SaaS →6 weeks

Runtime →8 weeks
PostgreSQL Global Development Group PostgreSQL 14 reaches end of life — after 12 November 2026 the community ships no further bug fixes or security patches for the 14.x line
