IcedTea-Web Release Notes

IcedTea-Web is available in two versions: Supported Availability (SA) for Azul customers and the free Community Availability (CA). The latest SA version is recommended over any CA version of IcedTea-Web, as it includes a broader set of bug fixes and features.

Note
Currently, CA and SA builds of IcedTea-Web use an independent versioning scheme, with no correlation between their version numbers. This may change in the future, as the version numbers of both builds are expected to be chronologically aligned.

Supported Availability (SA) Releases

Azul customers have access to the SA builds of IcedTea-Web, which include compatibility features that simplify the transition to OpenJDK:
