This release includes several bug fixes and improvements to robustness. This release note describes what’s different between Istio 1.1.2 and Istio 1.1.3.
Known issues with 1.1.3
- A panic in the Node Agent was discovered late in the 1.1.3 qualification process. The panic only occurs in clusters with the alpha-quality SDS certificate rotation feature enabled. Since this is the first time we have included SDS certificate rotation in our long-running release tests, we don’t know whether this is a latent bug or a new regression. Considering SDS certificate rotation is in alpha, we have decided to release 1.1.3 with this issue and target a fix for the 1.1.4 release.
