Each quarter, the Azure Sphere team works to open new scenarios to customers through new features on-chip and in the cloud. The Azure Sphere 19.05 release continues this theme by unlocking the real-time capable cores that reside on the MT3620. Co-locating these cores within the same SOC enables new, real-time scenarios on the M4 cores while continuing to support connectivity scenarios on the high-level core. This release also introduces support for DHCP-based Ethernet connections to the cloud.
The Azure Sphere public preview 19.05 feature release is available today via the Retail Evaluation feed. The regular Retail OS feed will continue to deliver version 19.04; we plan to upgrade it to 19.05 in two weeks.
Guardian modules are a new class of device built on Azure Sphere that protect brownfield equipment, mitigating risks and unlocking the benefits of IoT. They attach physically to brownfield equipment with no equipment redesign required, processing data and controlling devices without ever exposing vital operational equipment to the network.
The Azure Sphere public preview 19.04 quality release is available today via the Retail Evaluation feed. The regular Retail OS feed will continue to deliver version 19.03; we plan to upgrade it to 19.04 in two weeks.
The 19.03 release marks the beginning of a planned release schedule of one major feature release and two minor quality releases per quarter. As part of the 19.03 release, on March 14th, we released for the first time to the Retail Evaluation feed and started the 14-day evaluation window during which our partners can verify their applications against the new OS and determine if there are any compatibility issues. While we are still in preview, we expect that any issues encountered will be routed through our CSA/TSP community.
We now support both a Retail Evaluation feed and a Retail feed for the Azure Sphere OS. The 19.03 release will initially be available via the Retail Evaluation feed. The regular Retail OS feed will continue to deliver version 19.02; we plan to upgrade it to 19.03 in two weeks.
The Azure Sphere 19.02 release is available today. In our second quarterly release after public preview, our focus is on broader enablement of device capabilities, reducing your time to market with new reference solutions, and continuing to prioritize features based on feedback from organizations building with Azure Sphere.
Today, the Azure Sphere team is releasing an update to the 18.11 release. This will be an Azure Sphere OS release only and will be released via over-the-air update. There will be no update to the Azure Sphere SDK. This release brings improved Wi-Fi reliability. Please see the release notes for more details.
