Three days to OpenSSL 3.4's end of life — a quiet night on the feeds, a busy week ahead on the board

Nothing new entered or changed from the monitored feeds tonight, and no recorded date moved — an honest quiet night, not padded with far-off backfill. Two imminent Azure retirements came due for their under-30-day re-check and were re-confirmed by hand against Microsoft's release-communications API: Databricks Runtime 10.4 LTS still reaches end of life on 1 November 2026, and Azure Functions support for PowerShell 7.4 still ends 10 November 2026. The reason to look at the board tonight is timing: OpenSSL 3.4's end of life and the Minimus shutdown are both three days out, and nine more dated sunsets land before mid-November.

A quiet night. Nothing new surfaced from the 60 monitored feeds, and no recorded sunset date moved — so instead of reaching for a far-off entry to pad the page, tonight is a re-verification check and a look at a board that is about to get busy.

Re-verified tonight, no change

Two imminent Azure retirements were due for their under-30-day re-check. Both notices live on JavaScript-rendered Azure Updates pages our automated fetcher can’t read, so each time they come due we verify them by hand against Microsoft’s release-communications API. Both dates hold:

Azure Databricks Runtime 10.4 LTS reaches end of life on 1 November 2026 (“Azure Databricks Runtime 10.4 LTS will reach end of life on November 1, 2026”). Move workloads to a supported LTS runtime before then.
Azure Functions support for PowerShell 7.4 ends on 10 November 2026 — transition function apps to PowerShell 7.6; they keep running past the date but stop receiving security patches.

Still deliberately held off the board: the reported 15 October 2027 retirement of the Search-UnifiedAuditLog PowerShell cmdlet (in favour of the Microsoft Graph AuditLogQuery API). It is almost certainly real — Message Center notice MC1505599 — but that notice lives inside the Microsoft 365 admin center, and no public Microsoft page carries the date yet. No open-able official source, no published claim. We’re watching the cmdlet’s reference page for the public banner.

The next three weeks, every date verified against its primary source

22 Oct — OpenSSL 3.4 end of life and the Minimus shutdown
23 Oct — OpenAI removes GPT-4, GPT-3.5, o1 and o3 models
27 Oct — Kubernetes 1.34 end of life
30 Oct — Fitbit’s legacy Web API shutdown
31 Oct — Consul 1.22 end of life and OpenAI’s hosted Evals platform going read-only
1 Nov — Alpine 3.21 end of life, OpenSSL 3.6 end of life, and Azure Databricks Runtime 10.4 LTS (above)
2 Nov — GitHub Actions macOS 14 runner retirement and Mullvad’s encrypted DNS shutdown
10 Nov — .NET 8 and 9 end of support, Windows 11 23H2 end of servicing and Azure Functions PowerShell 7.4 (above)
12 Nov — PostgreSQL 14 end of life

Full board with live countdowns on the calendar.
