Version Identification 

• OTA file version: 01200403
• Application: 1.2.0
• Stack: 4.0.3

ubisys Compact7B Stack Changes between 3.0.0 and 4.0.3

• Zigbee 2023 compliant (passes all compliance tests, certification pending)
  • Asymmetric key agreement before network admission with optional device interview
  • Support for all mandatory and all optional features defined in Zigbee 2023 in all possible device roles: trust center, router, sleepy end-device, non-sleepy end-device
  • Support for all cryptographic suites supported by Zigbee 2023, i.e. SPEKE/Curve25519/AES-MMO-128/HMAC-AES-MMO-128 and SPEKE/Curve25519/SHA-256/HMAC-SHA-256-128
  • Fully standard-compliant Works With All Hubs feature support retaining full compatibility with the pre-standard Amazon Works With All Hubs cluster
  • Negotiation of fragmentation capabilities
  • Fragmentation support for new ZDO commands
  • APS security frame counter synchronization
  • Standardized trust center swap-out (trust center and joined devices)
  • Standardized network-level retries, including data poll retries for sleepy end-devices
• Enhanced product-level configuration options for customized stack behavior
• Optimizations to improve routing and instant network connectivity on start-up
• Ongoing maintenance of the code base: Restructuring, refactoring and consolidating
• Round-up of bug-fixes and performance improvements

Note: This change log is a generic stack change log. Products incorporating the stack can choose to enable specific feature sets. For example, the 2023 feature set can be selectively disabled in products to support a graceful transition to Zigbee 2023 in progressive roll-outs. In addition, while the stack supports all variations of key agreement suites, end-products might support only a reasonable subset. Specifically, ubisys products will prefer SPEKE/Curve25519/AES-MMO-128/HMAC-AES-MMO-128 for all Zigbee 2023, Zigbee Direct 1.0 and digital signatures of OTA images as this suite provides the best blend of security, performance and resource utilization.

ubisys Compact7B Stack Changes between 2.4.0 and 3.0.0

• Added support for I2C TAP
• Added support for a unified and fully configurable join/rejoin algorithm with back-offs and retries at the stack level
• Reject trust center rejoin on a distributed security network (CSA incident no. 2021-ZP-0401)
• Start TCLK exchange if an end device could not successfully finish TCLK exchange during its initial joining and has just rejoined
• Improved sleep management: Checking both transmission and reception queues for pending packets, if necessary
• Extended the advanced parent link maintenance mechanism by the new criterion „poor poll control reactivity“
• More granular startup progress notifications, including kick-off of a Touch Link commissioning procedure
• Stop ongoing join/rejoin retry attempts when Touch Link commissioning procedure is instigated
• Encapsulated the All Hubs cluster’s dependency on the Touch Link server, IAS Zone server and Time client clusters, for better modularity
• Added Enhancements to the Thermostat cluster
• Made the hard limit for the scene table capacity configurable
• Added support for the Relative Humidity Measurement cluster
• Added framework support for initiating enroll request and IAS zone status change indication via the ZCL request queue
• Added framework support for time query initiated by a Time client cluster
• Prohibit automatic CIE detection by default; application is still able to instigate it though should legacy systems require it
• Explicitly stop fast polling mode as soon as no more response frame is pending
• Resume network activity if a router device just failed a rejoin attempt
• Enhancement: PAN-ID and permit joining state changes are forwarded to application clusters
• Bug-fix: Under rare circumstances, a frame might linger in the transmission queue without being actually sent
• Bug-fix: Potential overflow of 64-bit timer values might occur when unsigned arithmetic is used for comparison of due times
• Bug-fix: During MAC association, if an unrelated frame is being received via data polling, MAC association might be incorrectly terminated; account for this case and retry if permissible
• Bug-fix: Periodical polling timer used to be unconditionally kept alive, even in case of data poll failure; temporarily cancel it to avoid interference with subsequent retry attempts. Once succeeded, the periodical polling timer will be reinstated for its normal usage.
• Bug-fix: When assessing MAC capability changes for a rejoining device verify the „Device Type“ and „Receiver on when Idle“ bits only
• Bug-fix: Skip route discovery table verification diagnostics in case of an end device
• Bug-fix: Limit the use of incoming APS security material to few select cases only
• Bug-fix: Periodical reporting on a cluster attribute could lead to undue delays of reports for other clusters
• Bug-fix: Startup behavior of the OnOff cluster might be incorrect due to interactions with Level Control or Color Control clusters on the same application endpoint
• Bug-fix: Brightness adjustment of the Level control cluster might be incorrect due to interactions with a Color Control cluster on the same application endpoint
• Bug-fix: Under rare circumstances, neighbor table entries might be incorrect (caused by a typo)
• Bug-fix: Under rare circumstances, out-of-sequence or truncated OTA data block could result in failed OTA download attempts
