DEV Community: Yury Atrashkevich

I made a GitHub Action that opens an issue before a vendor breaks your build

Yury Atrashkevich — Tue, 20 Oct 2026 12:07:25 +0000

Every few weeks some vendor retires something my code depends on. A runner label, a Lambda runtime, an OpenAI model, a GKE version. The notice exists - in a changelog, a deprecation table, an email to a billing inbox. We still find out when the build fails.

Dependabot tells you when a library is old. Nothing told me "this line in this repo stops working on Nov 2". So I made a small GitHub Action for that.

What it does

Once a week it reads your repo on the GitHub runner and looks for things that have a dated shutdown or price change. If it finds any, it opens one issue with the file and line, the date, days left and the fix. When you fix everything, the issue closes itself.

This is from the demo repo (full issue here):

Found 9 places hit by 9 vendor deadlines within 120 days.

[ ] GKE 1.31 extended support ends October 22, 2026 - 3 days left

infra/gke.tf:4 min_master_version = "1.31"

Fix: Upgrade the control plane, then each node pool, to 1.32 or newer before GKE does it for you.

[ ] OpenAI shuts down gpt-4, gpt-3.5-turbo, o1 and o4-mini on October 23 - 4 days left

src/ai/summarize.py:7 "gpt-4"

Fix: Change the model name: most go to gpt-5.6-sol or gpt-5.6-terra.

[ ] AWS Lambda Python 3.10 runtime deprecated October 31, 2026 - 12 days left

serverless.yml:4 runtime: python3.10

[ ] GitHub Actions macos-14 runners retire November 2, 2026 - 14 days left

.github/workflows/ci.yml:11 macos-14

Setup

One file, .github/workflows/deadline-check.yml:

name: Vendor deadline check
on:
  schedule:
    - cron: '17 6 * * 1'   # Mondays
  workflow_dispatch:
permissions:
  contents: read
  issues: write
jobs:
  deadlines:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: timetobail/deadline-check@v0

That's it. Options: days (default 120), fail-on-days if you want the job to fail when something is close, comment-on-pr.

What it knows about

114 rules for 94 dated changes, for example:

AI models: OpenAI (gpt-4, GPT-4o and 4.1 snapshots, TTS, Whisper), Gemini API and Vertex AI, Azure OpenAI, Amazon Bedrock, Claude
CI: GitHub Actions runners (macos-14, ubuntu-22.04), Azure Pipelines images, GitLab 20.0 removals, CircleCI images and APIs
Runtimes: AWS Lambda, Cloud Run functions, App Engine, Azure Functions, Heroku stacks
Kubernetes: GKE, EKS and AKS versions
Other: .NET 8/9, Prisma Accelerate, Bitbucket SSH host, Docker Content Trust

Every rule points to a dated change that comes from the vendor's own page (deprecation tables, changelogs, docs). No rumors, no "or later" dates.

Things I cared about

Your code never leaves the runner. The action makes one GET request for the public rules list. That's the only network call.
Strict rules. A false alarm is worse than a miss. "gpt-4" matches, "gpt-4o" doesn't. dotnet matches, dotnet-isolated doesn't. Comment lines are skipped.
One issue, not a flood. It updates the same issue every week.
Free. The action is MIT, the rules are open data (CC BY 4.0).

If it misses something in your stack, or flags something it shouldn't, open an issue with a small sample - I'll add or fix the rule. And I'm curious: which deprecation surprised you the most this year?

49 cloud and AI deadlines before the end of 2026 (with what to do for each)

Yury Atrashkevich — Mon, 19 Oct 2026 11:24:06 +0000

My day job is partly finops and vendor management. The thing I hate most: a vendor retires a model, a runtime or a plan, the notice goes to some billing inbox nobody reads, and we find out when the build fails or the invoice comes.

So I started to keep a list. Every row comes from the vendor's own page (docs, changelog, deprecation table), with the date and the first thing to do. Here is everything with a date between now and December 31, 2026 - 49 changes at 18 vendors.

⛔ = shutdown, nothing to move to inside the product. 💸 = you pay more if you do nothing. Everything else: change something and you can stay.

How this list is made

Only vendor pages count as sources: deprecation tables, changelogs, docs, official blog posts. If the vendor gives only a month or "or later", it's not on the list.
Each link goes to a page with all the dates, the steps, what you will see after the date (when the vendor says it) and the sources.
The full list, with early 2027 too, is here and updates itself as dates pass: Big vendor deadlines, Q4 2026. There are calendar feeds per vendor (AWS, Google Cloud, Microsoft, OpenAI, GitHub…) if you want these dates in your calendar.

If I missed something or got a date wrong, tell me in the comments with the vendor link and I'll fix it.
