Runtime Support
Runtimes on Cloud Functions include an operating system, software required to build and execute code written for a specific programming language, and software to support your function. Cloud Functions applies updates to runtimes in accordance with your selected security update policy.
Google provides support for a runtime during General availability (GA). During this support window:
- Runtime components are regularly updated with security and bug fixes. Updates are applied in accordance with your function's security update policy.
- To maintain stability, Cloud Functions avoids implementing breaking features or changes into the runtime. Breaking changes will be announced in advance in the Cloud Functions release notes.
When a language version is no longer actively maintained by the respective community, Cloud Functions will also stop providing maintenance and support for that language runtime. Before a runtime reaches the deprecation phase as described in the runtimes support schedule, Google will provide a notification to customers in Cloud Console.
Google may make changes to any runtime's support schedule or lifecycle in accordance with the terms of your agreement for the use of Google Cloud platform services.

Customer Support | GA-level support | No runtime support | No runtime support |
Notification Period
Cloud Functions will begin issuing in-app notifications 90 days before the runtime reaches deprecation. Upon notification, you should prepare to upgrade your function to a newer supported runtime.
Deprecation and Decommissioning
When a component is no longer actively maintained, Cloud Functions may deprecate and eventually remove the runtime.
This has three aspects: a publication of the deprecation date, a deprecation period, and a decommission date. In the following schedule the deprecation date is the start of the deprecation period, while the decommission date indicates the start of the decommission period.
During the deprecation period, you can generally continue to create new functions and update existing functions using the runtime. You should use this time to migrate functions that use the deprecated runtime to a more up-to-date runtime.
After the decommission date, you can no longer create new functions or update existing functions using the runtime. You must choose a more up-to-date runtime to deploy your functions. Functions that continue to use a decommissioned runtime may be disabled.
Support Schedule
Here is the list of supported Cloud Functions runtimes, as well as runtimes that have been deprecated or decommissioned.
Based on qualification and stability of releases, availability and key dates might be delayed. A blank deprecation or decommission date means that phase has not yet been scheduled. Revisit this page to stay up to date.
