Register assignment for parameters of a number of APIs changed with increased 42 scrutiny on their implementations. 43 44 - `decode_entity_auxiliary_names_pdr()` 45 - `decode_get_state_sensor_readings_resp()` 46 - `decode_platform_event_message_req()` 47 - `decode_platform_event_message_resp()` 48 - `decode_sensor_op_data()` 49 - `encode_get_state_effecter_states_resp()` 50 - `encode_state_effecter_pdr()` 51 - `encode_state_sensor_pdr()` 52 - `pldm_bios_table_append_pad_checksum()` 53 - `pldm_bios_table_attr_value_entry_encode_enum()` 54 - `pldm_bios_table_attr_value_entry_encode_string()` 55 - `pldm_pdr_find_record()` 56 - `pldm_pdr_get_next_record()` 57 583. platform: Support PLDM_CPER_EVENT in encode_platform_event_message_req() 59 604. dsp: firmware_update: Bounds check 61 decode_downstream_device_parameter_table_entry_versions() 62 63 The additional bounds-checking required the addition of further length 64 parameters. 65 66### Deprecated 67 681. oem: meta: Deprecate `decode_oem_meta_file_io_req()` 69 70 Users should switch to `decode_oem_meta_file_io_write_req()`. Modify this 71 function to make it safer. 72 73 Modification: 74 75 - The meaning of the returned result. 76 - Change parameters from individual pointers to a struct. 77 - Check the length provided in the message won't exceed the buffer. 78 792. pldm_entity_association_tree_copy_root() 80 81 The implementation allocates, but gives no indication to the caller if an 82 allocation (and hence the copy) has failed. Users should migrate to 83 pldm_entity_association_tree_copy_root_check(). 84 85### Removed 86 871.

Moved evolutions intended for v0.9.0 into place 146 147 Evolutions for the release have been moved from `evolutions/current` to 148 `evolutions/v0.9.1`. Library users can apply them to migrate off of 149 deprecated APIs. 150 151## [0.9.0] - 2024-09-07 152 153### Added 154 1551. base: Define macros for reserved TIDs 1562. pdr: Add pldm_entity_association_pdr_add_contained_entity_to_remote_pdr() 1573. pdr: Add pldm_entity_association_pdr_create_new() 1584. platform: Define macros for the responded transferflags 1595. pdr: Add pldm_pdr_get_terminus_handle() API 1606. pdr: Add related decode_entity_auxiliary_names_pdr() APIs 1617. fw_update: Add encode req & decode resp for get_downstream_fw_params 1628. platform: Add decode_pldm_platform_cper_event() API 1639. decode_get_pdr_repository_info_resp_safe() 164 165 Replaces decode_get_pdr_repository_info_resp() as discussed in the 166 `Deprecated` section below 167 16810. decode_get_pdr_resp_safe() 169 170 Replaces decode_get_pdr_resp() as discussed in the `Deprecated` section 171 below 172 173### Changed 174 1751. pdr: Stabilise related decode_entity_auxiliary_names_pdr() APIs 1762. platform: Rework decode/encode_pldm_message_poll_event_data() APIs 1773. platform: Stabilise decode_pldm_message_poll_event_data() APIs 1784.

Rename and deprecate functions with the `_check` suffix 192 193 All library function return values always need to be checked. The `_check` 194 suffix is redundant, so remove it. Migration to the non-deprecated 195 equivalents without the `_check` suffix can be performed using 196 `scripts/ apply-renames` and the [clang-rename][] configurations under 197 `evolutions/` 198 199 The deprecated functions: 200 201 - `get_fru_record_by_option_check()` 202 - `pldm_bios_table_append_pad_checksum_check()` 203 - `pldm_bios_table_attr_entry_enum_decode_def_num_check()` 204 - `pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()` 205 - `pldm_bios_table_attr_entry_enum_decode_pv_num_check()` 206 - `pldm_bios_table_attr_entry_enum_encode_check()` 207 - `pldm_bios_table_attr_entry_integer_encode_check()` 208 - `pldm_bios_table_attr_entry_string_decode_def_string_length_check()` 209 - `pldm_bios_table_attr_entry_string_encode_check()` 210 - `pldm_bios_table_attr_value_entry_encode_enum_check()` 211 - `pldm_bios_table_attr_value_entry_encode_integer_check()` 212 - `pldm_bios_table_attr_value_entry_encode_string_check()` 213 - `pldm_bios_table_string_entry_decode_string_check()` 214 - `pldm_bios_table_string_entry_encode_check()` 215 - `pldm_entity_association_pdr_add_check()` 216 - `pldm_entity_association_pdr_add_from_node_check()` 217 - `pldm_pdr_add_check()` 218 - `pldm_pdr_add_fru_record_set_check()` 219 220[clang-rename]: https://clang.llvm.org/extra/clang-rename.html 221 2222. `decode_get_pdr_repository_info_resp()` 223 224 Users should move to `decode_get_pdr_repository_info_resp_safe()` which 225 eliminates the opportunity for buffer overruns when extracting objects from 226 the message. 227 2283. `decode_get_pdr_resp()` 229 230 Users should move to `decode_get_pdr_resp_safe()` which reduces the 231 invocation tedium and improves memory safety over `decode_get_pdr_resp()`. 232 233### Removed 234 2351.
