v0.10.2

Changed

• Export SignedMessage type from GossipLog

v0.10.1

Changed

• Added JS-like number type to ModelDB
• Added listSessions(), getSession() to AbstractSessionSigner

v0.10.0

Changed

• Rewrites networking, Merkle sync is now non-blocking on both browser and server
• Adds experimental WebRTC gossiplog module
• Better support for concurrent mergeable values. Adds tracking of unique branches in GossipLog
• Handle undefined in range expressions and action arguments (undefined will be dropped in objects, or replaced with null in arrays)
• Renamed export() to getMessages() in GossipLog
• Fixes issues with experimental wallets

v0.8.29

Changed

• Fix an issue where the connected peer list could fail to update under heavy load

v0.8.28

Changed

• Bug fixes and stability improvements
  • Clean up GossipLog instances when closing Canvas core
  • Throw errors when writing to a GossipLog that has been closed
  • Improve handling of actions with missing sessions
  • Patch autoDialPeerRetryThresholdMs in the libp2p connection manager, because it isn't passed to the dialer component. (Default to 1000ms in the browser)
  • Upgrade to libp2p 1.5.1

v0.8.27

Changed

• Adds isUniversalReplication?: boolean option to the discovery service. By default, replication servers will not auto-start topics that are only signaled by other replication servers.
• Adds bannedTopics?: () => string[] option to the discovery service. Banned topics will not be signaled over active discovery, and replication servers will refuse to replicate them.
• Adds @canvas-js/probe-server, which uses a headless Chromium browser to verify that replication servers are online.
• Better metrics and monitoring.

v0.9.1

Changed

• Minor bugfixes and improvements
  • Signer methods are now Awaitable<T> instead of Promise<T>
  • Cosmos signers now accept a bech32Prefix
  • Updated dependencies

v0.9.0

Changed

• This release introduces new codecs and signed data formats in order to support onchain action/session verification.
  • To create actions/sessions that can be verified onchain, use Eip712Signer to sign sessions, and Secp256k1DelegateSigner to sign actions. By default, applications use SIWESigner and Ed25519DelegateSigner.
  • Data formats have changed, and are no longer compatible with past versions' data stored on disk. Applications will need to be reset when moving to 0.9.
• No further changes are planned for data formats or signatures at this time, so the next release (v0.10) will only be a networking upgrade.
• This release is optimized for server-to-server sync only, so browser-to-server sync applications (e.g. using full Canvas/libp2p nodes in the browser) should stay on v0.8.26 until v0.10 is released.

Added

• Added packages/ethereum-contracts with Solidity contracts and examples.
• Added Postgres support. Canvas applications, ModelDB databases, and GossipLog instances can now use Postgres v14+ as a backing store.

Signers

• Ethereum EIP712 + Secp256k1
• Ethereum SIWE + Ed25519
• Solana SIWS + Ed25519 (beta)
• Cosmos / Terra / Evmos via Cosmos Wallet / Evmos via Ethereum Wallet (beta)
• Substrate / Polkadot (unstable)
• Bluesky (unstable)
• NEAR (unstable)

v0.8.26

Changed

• Better logging for some errors that are part of normal expected behavior.
• Add websocket proxy for apps running using canvas run on Fly.io, so other peers can discover them.

v0.8.25

Changed

• Accept PrivateKeyAccount objects as signers for @canvas-js/chain-ethereum-viem.
• Improve connection reliability for apps running without sequencing/history indexing.
