April 2026 monthly highlights for jenkinsci/ec2-plugin: Fixed a critical NPE in EC2Cloud.readResolve by moving the initialization of cachedTemplateSlaves earlier in the method, ensuring initialization before early returns in the credential migration path. The change, implemented via commit 127f0f109c299eb125a0bd55451f9b55add7a41b, addresses issues #2002-2004 and stabilizes EC2 Cloud startup when legacy credentials are present. This repair reduces startup failures, increases reliability of EC2 template handling, and lowers support incidents related to NPEs during credential migration.
