v10.7.0

v10.7.0 graduates the Microsoft.Extensions.Diagnostics.ResourceMonitoring.Kubernetes package to stable. The package registers a Kubernetes-aware ResourceQuotaProvider that reads the pod's CPU and memory requests and limits and exposes them to Microsoft.Extensions.Diagnostics.ResourceMonitoring as baseline and maximum quotas, which then feed the request and limit dimensions of the published resource utilization metrics. The companion ResourceQuota and ResourceQuotaProvider types in Microsoft.Extensions.Diagnostics.ResourceMonitoring graduate to stable in the same change so that consumers can implement custom quota providers without taking an experimental dependency.

On the AI side, Microsoft.Extensions.AI.OpenAI moves to OpenAI 2.11.0 and fixes a deserialization bug in ToolJson.AdditionalProperties so that JSON Schema additionalProperties values shaped as sub-schema objects (for example {"type":"string"}) are preserved instead of throwing during deserialization. HostedFileContent.SizeInBytes and HostedFileContent.CreatedAt graduate to stable since both values are consistently available across hosted-file providers, while Purpose and Scope remain experimental as provider-shaped vocabulary. FunctionInvokingChatClient drops a backward-compat path that auto-marked ToolApprovalResponseContent entries with InformationalOnly: true; consumers that need to continue accepting sessions serialized before #7468 can use the sample ApprovalHistoryNormalizingChatClient middleware added in the test project.
