TheThingsNetwork/lorawan-stack v3.25.0

on GitHub

🚧 This release contains a critical bug which renders component communication unusable after 24 hours. The fix will be part of the v3.25.1 release. 🚧.

Added

• Optional Network Server database migration that removes obsolete last invalidation keys is now available.
• LoRaWAN Application Layer Clock Synchronization support.
  • It is available using the alcsync-v1 application package.
  • Can be enabled using the Console by visiting the application settings and ticking the Use Application Layer Clock Synchronization checkbox. By default, the package will operate on FPort 202.
• Drop uplink frames with CRC failure.

Deprecated

• Returning special float values, such as NaN and Infinity as part of the decoded payloads.
  • While the concepts of NaN and Infinity are part of JavaScript, JSON does not have a dedicated value for such values.
  • Historically we have rendered them in their string form, i.e. "NaN" and "Infinity", but this form is not standard nor accepted by the standard libraries of most programming languages (at least by default).
  • Most usages of NaN are actually result of operations with the JavaScript concept of undefined, and are not intentional. Mathematical operations that interact with undefined return NaN - for example undefined * 5 is NaN. It is not hard to reach undefined in JavaScript, as array access to undefined indices is undefined, and payload decoders generally work by consuming the frame payload bytes.
  • Future The Things Stack versions may not render such values, or may discard the decoded payload completely. The deprecation discussion can be tracked on GitHub.

Removed

• Automatic migrations of the Network Server database using ns-db migrate from versions prior to v3.24 are removed. Migrating from prior versions should be done through v3.24 instead.
