The Minnesota release is version 3.0 (the 12th overall release and the third major release behind the Edinburgh and Ireland releases). Due to API and other tech debt changes, Minnesota is NOT backward compatible with the EdgeX 1.x or EdgeX 2.x releases. The release is not an LTS release. Jakarta (2.1) remain an LTS release. It is anticipated that the community will create its second LTS on top of Minnesota in the fall or 2023 (the Napa 3.1 release),

Upgrade to Go 1.20
Requirements (UCR) and design (ADR) now in place for configuration via URIs. Likely to be implemented in the next minor release. Had a dependency on the Common Configuration added in this release. https://docs.edgexfoundry.org/3.0/design/ucr/URIs-for-Files/ and https://docs.edgexfoundry.org/3.0/design/adr/0027-URIs%20for%20Files/
Requirements (UCR) in place for Bring Your Own Vault (BYOV) allowing for an environment where an existing Vault instance is not setup by EdgeX: https://docs.edgexfoundry.org/3.0/design/ucr/Bring-Your-Own-Vault/
Requirements (UCR) in place for Core Data Retention - that is a configurable cache of data held by EdgeX: https://docs.edgexfoundry.org/3.0/design/ucr/Core-Data-Retention/
Added a STRIDE security threat model for identifying and mitigating risks in EdgeX: https://docs.edgexfoundry.org/3.0/threat-models/stride-model/EdgeX-STRIDE
- STRIDE stands for Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, Elevation of privilege
EdgeX has moved its external facing chat to GitHub Discussions allowing for communication to be better kept, searched and tagged (compared to the EdgeX slack channels). We are seeing multiple community discussions started each day on GitHub

An error occurs when using an external MQTT connection with SecretName (vs SecretPath): https://github.com/edgexfoundry/go-mod-bootstrap/issues/550.
- Workaround is here: https://docs.edgexfoundry.org/3.0/microservices/core/command/Ch-Command/#configuring-for-secure-mqtt-connection
- This issue is fixed in v3.1.
Insecure secrets callback does work for removed secrets: https://github.com/edgexfoundry/go-mod-bootstrap/issues/534. This applies to any map in Writable section (ASC pipeline functions, etc).
- The workaround is to restarting service after removing entry.
- This issue will be fixed in future v3.x release
App Service template not using released version of App SDK: https://github.com/edgexfoundry/app-functions-sdk-go/issues/1427.
- The work around is to set the App SDK version in your new app service to v3.0.0 when using the App Service template.
- This issue is fixed in v3.1.
The start time and end time fields of the Interval object in the Support Scheduler service always use UTC to run scheduling: https://github.com/edgexfoundry/edgex-go/issues/4594, but they should use the local timezone of the host system.
- This issue is fixed in v3.1.
Device USB Camera service will panic when adding device manually if CardName or SerialNumber data are missing: https://github.com/edgexfoundry/device-usb-camera/issues/263.
- The work around is to follow the documentation here when adding devices manually.
- This issue is fixed in v3.1.
Unable to update existing devices using the Device C SDK function edgex_metadata_client_add_or_modify_device(). https://github.com/edgexfoundry/device-sdk-c/issues/452.
- This issue is fixed in v3.1.
App Service's standard routes (/version, /config, /secret) are not secured when running in Secure mode. https://github.com/edgexfoundry/app-functions-sdk-go/issues/1435
- This has been fix in 3.0.1 patch releases of the App Functions SDK, App Service Configurable and App RFID LLRP Inventory. https://github.com/edgexfoundry/app-functions-sdk-go/pull/1447
App Service Configurable's external-mqtt-trigger profile is missing InsecureSecrets section for MQTT. https://github.com/edgexfoundry/app-service-configurable/issues/578
- Work around it to add the InsecureSecrets section manually and set SecretName properly as is done in this fix for Napa. https://github.com/edgexfoundry/app-service-configurable/pull/579/files
  - This can be done in the configuration.yaml and rebuild docker image or in Consul once service has started.
- This issue is fixed in v3.1.
The Device C SDK is unable to correctly parse the Unicode replacement rune in the JSON payload received from the message bus. https://github.com/edgexfoundry/device-sdk-c/issues/465.
- Workaround is here: https://github.com/edgexfoundry/device-sdk-c/issues/465#issuecomment-1705827784
- This issue is fixed in v3.1.
