Customers may see increased build times for code-based AWS App Runner services for older managed runtimes.

**Release date:** Jun 14, 2024

## Changes


Starting from 17 Jun, 2024, customers using the following runtimes are expected to see an increase in build time by approximately 240 seconds.
+ Node.js 12
+ Node.js 14
+ Corretto 8
+ Corretto 11
+ Python 3.7
+ Python 3.8

To maintain similar build times, we recommend that Node.js 12 and Node.js 14 users migrate to Node.js 18 and that Python 3.7 and Python 3.8 users migrate to Python 3.11. Otherwise, since builds are billed by time, expect an associated increase in cost. For more information about App Runner pricing, see
