What changed
Time to bail on Cloud Run functions on Python 3.10? Act. You can stay. After April 4, 2027, Python 3.10 functions cannot be created or updated, and may be disabled.
On our scale this is Act: change a setting or plan before the date. You can stay.
Google decommissions the Python 3.10 runtime (python310) for Cloud Run functions on April 4, 2027. After that you cannot create or update these functions, and they may be disabled.
Here are the facts we checked:
- Decommission date: April 4, 2027 (Google Cloud)
- Runtime: Python 3.10, runtime ID python310 (1st gen and Cloud Run functions) (Google Cloud)
- Deprecated since: October 4, 2026 (Google Cloud)
- After decommission: You can no longer create new workloads or update existing ones on the runtime (Google Cloud)
- If you do nothing: Functions that stay on a decommissioned runtime may be disabled (Google Cloud)
- Cloud Run source deploys: The python310 runtime on Cloud Run has the same dates (Google Cloud)
- Can the dates change?: Google says key dates might be delayed (Google Cloud)
- Next Python runtime: Python 3.11: deprecated October 24, 2027; decommissioned April 24, 2028 (Google Cloud)
- Newer runtimes: python312 is decommissioned April 2, 2029, python313 April 10, 2030, python314 April 10, 2031 (Google Cloud)
- Functions still on Python 3.10: Cannot be updated after April 4, 2027 and may be disabled (Google Cloud)
You can stay on Cloud Run functions. You have to change a setting or plan before the date.
Leaving is a choice here, not a must.

The date to remember is April 4, 2027. Make the change before then.
What to do before April 4
- Find functions on Python 3.10. In the console, check the runtime of each function. Note every one on python310.
- Change the runtime. Set the runtime to python312, python313 or python314 and update your dependencies.
- Deploy each function again. Deploy and test every function before April 4, 2027.
A few tips:
- Make the change yourself before the date. Do not wait for the last reminder email.
- Write down your current plan or settings first, so you can compare after the change.
- After the change, open your settings again and check that it worked.
