now fails if supplied source stream is empty
- The "con" attribute is now included in anjay_dm_oi_attributes_t, as it has
been standardized for LwM2M TS 1.2
- Refactored public headers to consistently use conditional compilation; APIs

version; the features include:
- Support for TCP binding
- Support for SenML JSON, SenML CBOR and raw CBOR content formats

Bootstrap Server or the bootstrapper module onto hardware security engines
(note: no hardware security engine implementation is provided in the open

module and automatically moved onto hardware security engine can now be marked
as "permanent" to prevent them from being removed

AVS_NET_SOCKET_HAS_BUFFERED_DATA feature added in avs_commons 5.0
- Refactored and simplified internal flow of calling data model handlers
- Refactored internal handling of communication state
- Commercial features are now available for separate inclusion, described in the
documentation more clearly and feature code examples
- Various improvements in the documentation
Bugfixes:
- Fixed some uninitialized variables in IPSO object implementations
- Fixed some compilation warnings in unit tests
- Fixed compatibility of integration tests with OpenSSL 3
- Fixed socket flag handling in tests that were breaking with some versions of
Python
- Fixed some obsolete information in Doxygen documentation
