1.1.0

What's New

ASiC-E (Extended) Container Support

• Multiple files in a single container — CreateExtendedAsync bundles multiple files with an ASiCManifest XML listing each file's digest, all covered by a single timestamp
• CreateExtendedFromFilesAsync — convenience method for timestamping files directly from disk
• ExtractAll — extract all data files from both ASiC-S and ASiC-E containers
• Auto-detection in Verify — ASiC-E containers are detected by MIME type or manifest presence

Configurable Per-File Size Limit

• MaxFileSize option (default 10 MB) — rejects oversized files before processing to prevent memory exhaustion
• Set to null to disable the limit
• Enforced on create, extract, and verify operations

Timestamp Renewal for Long-Term Archival

• RenewAsync / RenewFileAsync — re-timestamp containers per ETSI EN 319 162-1 §5.4
• Each archive timestamp covers the previous token's bytes, creating a verifiable chain (timestamp.tst → timestamp-002.tst → timestamp-003.tst)
• Verification walks the full chain automatically
• New TimestampChainEntry model and TimestampChain property on AsicVerifyResult
• CLI: asicts renew <file> command

Other

• Updated package dependencies
• Updated README with ASiC-E examples and MaxFileSize documentation
• STRIDE threat model updated to v1.3
