- 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

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.
