v0.5.0

0.5.0 (2026-11-12)

⚠ BREAKING CHANGES

• the health service, the tedge_Agent name, the parameter sets, and the Smart Function rules are renamed. cumulocity/README.md, "Moving a tenant from tedge-zephyr names", lists what a tenant needs: the new rules (with the old ones deleted), the new DTM definitions, and the removal of the old fragments and service.

v0.2.0

0.2.0 (2026-11-09)

⚠ BREAKING CHANGES

• core: struct tedge_remote_target, passed to the remote_access_allow hook, carries the target as host (as the operator named it) and ipv4 (4 bytes, network order) instead of a Zephyr struct sockaddr *addr. tedge.h no longer includes a Zephyr network header for it.

Bug Fixes
