v1.5.0 - Virtual A/B Compression Metadata Integration

What's New in v1.5.0

Virtual A/B Compression (VABC) Metadata Integration

This release introduces full support for extracting and using Virtual A/B compression metadata from Stock ROMs.

payload-dumper Enhancement

The payload-dumper binary now extracts dynamic_partition_metadata from payload.bin via the --json flag:

• cow_version: COW format version for snapshot optimization
• compression_factor: Compression factor value
• snapshot_enabled: Virtual A/B snapshot status
• vabc_enabled: Virtual A/B compression enablement
• vabc_compression_param: Compression algorithm (lz4, gz, etc.)

OTA Packaging Improvements

• VABC metadata is now automatically stored in partition_info.json
• misc_info.txt uses accurate VABC settings from Stock ROM:
  • virtual_ab_compression_method
  • virtual_ab_cow_version
  • virtual_ab_compression_factor

Bug Fixes

• Fixed resume context handling when stock attribute is not set
