The FileBrowser Quantum fork reached 2.0 stable on October 9, 2026 with an activity log, per-storage-source permissions, and a BoltDB-to-SQLite migration, followed on October 13 by a fix for two security flaws. Prepare a real migration procedure before upgrading your 1.x instances.
On October 13, 2026, Microsoft killed Publisher: Microsoft 365 subscribers can no longer open their PUB files, a proprietary format three decades old. LibreOffice and Scribus, through the reverse-engineered libmspub library, reopen those documents: migrate them to ODF now, while they are still readable.
On October 16, 2026, AWS made Azure SDK to AWS SDK code conversion generally available in AWS Transform: Azure Functions becomes Lambda, Blob Storage becomes S3, and Cosmos DB becomes DynamoDB in preview. For a .NET team weighing an exit from Azure, it is a serious starting point — not a one-click migration.
Kubernetes has deprecated cgroup v1 and plans its full removal in v1.38; since v1.35, the kubelet refuses to start on a node still running cgroup v1. If your nodes are still on cgroup v1, migrate them to cgroup v2 before upgrading, or the cluster will fail to start.
GitHub will retire the macOS 14 runner image on November 2, 2026 and is already failing jobs that still use it during eight brownout windows spread across October. Migrate your workflows to an arm64 label — macos-15 or macos-latest — before the next outage on October 12.
On 17 September 2026 GitHub announced that the ubuntu-latest label is moving from Ubuntu 24.04 to 26.04, rolling out gradually between 19 October and 19 November 2026. The migration ships a JDK jump from 17 to 25, major-version bumps for Docker Compose and Helm, and the removal of a dozen preinstalled tools: workflows that don’t pin their runtime will break.
On November 12, 2025, Kubernetes announced the retirement of ingress-nginx; upstream maintenance stopped in March 2026 and the last patch bridge, Microsoft’s for AKS, expires in November 2026. Every annotation in your fleet now has to become a Gateway API route — or remain an unpatched vulnerability.
On September 8, Jellyfin released version 12.0, which drops the “10.” prefix and concentrates most of its work on the performance inherited from the 10.11 rewrite. The migration changes the database with no way back: backup, plugin removal, and a full library scan are mandatory before you reap the gains.
File Browser, the self-hosted web file manager with 36,000 GitHub stars, shipped its last release v2.63.23 on July 27, 2026 and archived its repository on September 1, 2026: no more security fixes will follow. Audit your exposed instances and migrate to a maintained alternative.
On August 13, 2026, the PostgreSQL project released 18.6, 17.11, 16.15, 15.19, 14.24 and 19 Beta 3, fixing 28 security vulnerabilities — a record — including a dozen memory bugs exploitable for code execution. Apply the minor release now, and if you are still on version 14, plan the major upgrade before November 12, 2026.
The ingress-nginx project ends all maintenance in March 2026. The GitHub repository has been archived since March 24, no further security patches will be published, and CVE-2025-1974 demonstrated the architectural risks of a controller built on arbitrary annotations. Gateway API is the mandatory migration target, and it’s ready.
