v0.18.0

0.18.0 (2026-03-10)

This release introduces multi-copy storage for data durability. Uploads now automatically store 2 copies of your data across independent Filecoin storage providers. Each copy is independently proven on-chain, so a single provider failure doesn't result in data loss. The number of copies can be controlled with --count, and you only upload your data once regardless of copy count.

Also fixes --mainnet support across the CLI, a terminate command for dataset lifecycle management, and local devnet support for development.

• multi-copy storage: uploads now create 2 independently-proven copies across different storage providers by default for data durability (synapse-sdk 0.38, synapse-core 0.2) (#343) (9a87038)
