 ### Changed
 
-**[SDK]** `SEVSNPProvider` now uses the kernel configfs-TSM interface (`/sys/kernel/config/tsm/report`, kernel 6.7+) for bare-metal / non-paravisor SNP guests; the previous `/dev/sev-guest` ioctl path (never hardware-validated, incorrect ABI) has been removed. On Azure use `AzureCVMProvider`.

On Azure use `AzureCVMProvider`.
 **[SDK]** Attestation providers (`AzureCVMProvider`, `SEVSNPProvider`, `TDXProvider`, `OPAQUEProvider`, `TPMProvider`) and the chain verifier are now exported from `agent_manifest`; CLI `manifest attest` accepts `--provider azure-cvm`.
