Anjay Lite 2.0.0

BREAKING CHANGES

• Removed support for TCP and TLS bindings in NET layer -
  ANJ_NET_WITH_TCP, ANJ_COAP_WITH_UDP, ANJ_COAP_WITH_TCP options were removed.
• Removed anj_net_shutdown from NET layer.
• Monotonic time is now the primary clock used for scheduling operations,
  replacing real-time clock usage across the codebase.

Features

• NTP module for time synchronization.
• (commercial version only) Added default OSCORE Object implementation.
• Added support for canceling observations with CoAP RST message.
• Re-introduced anj_core_ongoing_operation API.
• Added ANJ_OBSERVE_OBSERVATION_CANCEL_ON_TIMEOUT option to control behavior
  in case of notification timeouts.
• Introduced ANJ_LOG_MICRO option for optimizing footprint of
  logging with tools/micro_logs_decode.py tool to decode log messages.

Improvements

• Switch RNG implementation from getrandom() to getentropy() for improved portability.
• Tests structure refactored in order to increase coverage.
• Shorter Send operation payloads due to the use of a common path when encoding messages.
• MbedTLS integration layer sets the correct MTU value.
• MbedTLS is now fetched and compiled only once when calling make all via root CMakeLists.txt.

Bugfixes

• Fixed a bug in TLV decoder that incorrectly rejected request with a resource
  instance specified in the uri-path.
• Fixed handling of Discover requests targeting the root path.
• Fixed incorrect descriptions of return values in callbacks from FOTA.
• Writes to Object Instances now ignore unknown optional Resources, per LwM2M specification.

Anjay Lite 1.0.0

The first Anjay Lite release featuring stable API.

BREAKING CHANGES

• Implemented new Time API with distinct clock types:
  anj_time_real_t, anj_time_monotonic_t, anj_time_duration_t.
• Renamed anj_dm_res_t::operation field to anj_dm_res_t::kind.
• Renamed anj_dm_res_operation_t type to anj_dm_res_kind_t.
• Moved anj/log/log.h header to anj/log.h.
• Removed anj_core_ongoing_operation API.
• Removed anj_dm_bootstrap_cleanup API.

Bugfixes

• Fixed broken README.md link in integrations documentation

Anjay Lite 1.0.0-beta.2

Second release for Anjay Lite Beta.

BREAKING CHANGES

• Changed error codes defined in the anj_net_api.h to positive values. Returning any positive values from the
  user Network API implementation, other than ANJ_NET_E*, is prohibited.

Features

• CoAP Downloader module for large file transfers from CoAP servers, supporting FOTA Pull scenarios.
• Added support for Write-Composite operation.

Improvements

• Added anj/init.h header to make config includes and option dependency checks
  more consistent.
• Removed unnecessary usages of ANJ_CONTAINER_OF() in object implementation
  examples.
• Introduce Python tools for downloading object XMLs from OMA registry - tools/lwm2m_object_registry.py and generating
  object stubs - tools/anjay_codegen.py
• Implemented responses caching
• If no confirmable notification is sent for 24 hours, the next notification sent will be confirmable.
• The library now follows the include pattern recommendations from Include What You Use (IWYU) version 0.24
  compatible with clang 20.

Bugfixes

• Fixed improper handling of LwM2M Server responses in Separate Response mode.
• Updated default value in description of ANJ_COAP_MAX_OPTIONS_NUMBER option.
• Fixed an issue with calling the observation module API during message exchange handling.
• Corrected the timing for setting the last sent notification timestamp.
• Fixed an issue that allowed server both bootstrap and management to freely read
  the Security and OSCORE objects.
