ABI break for pldm_pdr_find_record() 41 42 Register assignment for function parameters was changed with the removal of 43 some asserts in related implementations. 44 453. ABI break for pldm_pdr_get_next_record() 46 47 Register assignment for function parameters was changed with the removal of 48 some asserts in related implementations. 49 50### Deprecated 51 521. oem: meta: Deprecate `decode_oem_meta_file_io_req()` 53 54 Users should switch to `decode_oem_meta_file_io_write_req()`. Modify this 55 function to make it safer. 56 57 Modification: 58 59 - The meaning of the returned result. 60 - Change parameters from individual pointers to a struct. 61 - Check the length provided in the message won't exceed the buffer. 62 632. pldm_entity_association_tree_copy_root() 64 65 The implementation allocates, but gives no indication to the caller if an 66 allocation (and hence the copy) has failed. Users should migrate to 67 pldm_entity_association_tree_copy_root_check(). 68 69### Removed 70 711.

Moved evolutions intended for v0.9.0 into place 104 105 Evolutions for the release have been moved from `evolutions/current` to 106 `evolutions/v0.9.1`. Library users can apply them to migrate off of 107 deprecated APIs. 108 109## [0.9.0] - 2024-09-07 110 111### Added 112 1131. base: Define macros for reserved TIDs 1142. pdr: Add pldm_entity_association_pdr_add_contained_entity_to_remote_pdr() 1153. pdr: Add pldm_entity_association_pdr_create_new() 1164. platform: Define macros for the responded transferflags 1175. pdr: Add pldm_pdr_get_terminus_handle() API 1186. pdr: Add related decode_entity_auxiliary_names_pdr() APIs 1197. fw_update: Add encode req & decode resp for get_downstream_fw_params 1208. platform: Add decode_pldm_platform_cper_event() API 1219. decode_get_pdr_repository_info_resp_safe() 122 123 Replaces decode_get_pdr_repository_info_resp() as discussed in the 124 `Deprecated` section below 125 12610. decode_get_pdr_resp_safe() 127 128 Replaces decode_get_pdr_resp() as discussed in the `Deprecated` section 129 below 130 131### Changed 132 1331. pdr: Stabilise related decode_entity_auxiliary_names_pdr() APIs 1342. platform: Rework decode/encode_pldm_message_poll_event_data() APIs 1353. platform: Stabilise decode_pldm_message_poll_event_data() APIs 1364. ABI break for decode_sensor_op_data() 137 138 Applying LIBPLDM_CC_NONNULL to the internal msgbuf APIs caused 139 abi-compliance-checker to flag a change in the register containing the 140 parameter `previous_op_state`. 141 1425. platform: Stabilise decode_pldm_platform_cper_event() API 1436. oem: meta: Stabilise decode_oem_meta_file_io_write_req() API 1447. oem: meta: Stabilise decode_oem_meta_file_io_read_req() API 1458. oem: meta: Stabilise encode_oem_meta_file_io_read_resp() API 146 147### Deprecated 148 1491. Rename and deprecate functions with the `_check` suffix 150 151 All library function return values always need to be checked. The `_check` 152 suffix is redundant, so remove it. Migration to the non-deprecated 153 equivalents without the `_check` suffix can be performed using 154 `scripts/ apply-renames` and the [clang-rename][] configurations under 155 `evolutions/` 156 157 The deprecated functions: 158 159 - `get_fru_record_by_option_check()` 160 - `pldm_bios_table_append_pad_checksum_check()` 161 - `pldm_bios_table_attr_entry_enum_decode_def_num_check()` 162 - `pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()` 163 - `pldm_bios_table_attr_entry_enum_decode_pv_num_check()` 164 - `pldm_bios_table_attr_entry_enum_encode_check()` 165 - `pldm_bios_table_attr_entry_integer_encode_check()` 166 - `pldm_bios_table_attr_entry_string_decode_def_string_length_check()` 167 - `pldm_bios_table_attr_entry_string_encode_check()` 168 - `pldm_bios_table_attr_value_entry_encode_enum_check()` 169 - `pldm_bios_table_attr_value_entry_encode_integer_check()` 170 - `pldm_bios_table_attr_value_entry_encode_string_check()` 171 - `pldm_bios_table_string_entry_decode_string_check()` 172 - `pldm_bios_table_string_entry_encode_check()` 173 - `pldm_entity_association_pdr_add_check()` 174 - `pldm_entity_association_pdr_add_from_node_check()` 175 - `pldm_pdr_add_check()` 176 - `pldm_pdr_add_fru_record_set_check()` 177 178[clang-rename]: https://clang.llvm.org/extra/clang-rename.html 179 1802. `decode_get_pdr_repository_info_resp()` 181 182 Users should move to `decode_get_pdr_repository_info_resp_safe()` which 183 eliminates the opportunity for buffer overruns when extracting objects from 184 the message. 185 1863. `decode_get_pdr_resp()` 187 188 Users should move to `decode_get_pdr_resp_safe()` which reduces the 189 invocation tedium and improves memory safety over `decode_get_pdr_resp()`. 190 191### Removed 192 1931.
