Recently changed requirements

• v1.61.0api-propagators.md#get-global-propagatorMUST relaxed to SHOULD: This method SHOULD exist for each supported Propagator type.
• v1.61.0api-propagators.md#set-global-propagatorMUST relaxed to SHOULD: This method SHOULD exist for each supported Propagator type.
• v1.61.0README.md#attribute-limitsMUST added: the SDK MUST start counting depth at 1 for the top-level attribute value, and increment depth when descending into arrays (both homogeneous and heterogeneous) or maps;
• v1.61.0README.md#attribute-limitsMUST added: arrays or map at a depth greater than the limit MUST be replaced with an empty value;
• v1.61.0README.md#attribute-limitsMUST NOT added: otherwise a value MUST NOT be changed due to the depth limit.
• v1.61.0document-status.md#maturity-levelsMUST removed: They also MUST communicate in which version they will be removed. | | Unmaintained | A component identified as unmaintained does not have an active code owner.
• v1.60.0sdk.md#emit-a-logrecordMUST added: Enabled: If the Logger is not enabled (i.e. LoggerConfig.enabled is false), the log record MUST be dropped.
• v1.60.0sdk.md#createMUST added: When both Entities and Attributes are provided in the create method, the system MUST behave as if a Resource is created with just Attributes and then merges with another Resource created with just Entities.
• v1.60.0sdk.md#mergeMUST added: If either resource contains Entities then merge behavior with Entiites MUST be used, otherwise merge behavior without Entities MUST be used.
• v1.60.0sdk.md#merge-behavior-with-entitiesMUST added: When either Resource contains entities, the merge operation MUST follow the resource data model's merge algorithm.
• v1.60.0sdk.md#merge-behavior-with-entitiesMUST added: The resulting SchemaURL MUST match the behavior defined in the merge algorithm.
• v1.60.0sdk.md#retrieve-attributesMUST added: When entities are enabled and present for the Resource, this list MUST include all attributes, including those associated with entities.
• v1.59.0env-carriers.md#process-spawningMUST NOT removed: The language implementations MUST NOT handle spawning processes.
• v1.59.0env-carriers.md#propagator-mechanismsMUST NOT added: Language implementations MUST NOT spawn child processes as part of environment variable context propagation.
• v1.59.0env-carriers.md#propagator-mechanismsSHOULD added: Language implementations SHOULD document operational guidance, including initialization-time extraction, child process environment handling, and security considerations.
• v1.59.0sdk.md#getsamplingintentSHOULD added: The calling CompositeSampler SHOULD update the threshold of the outgoing TraceState, as described above.
