v0.8.3-rc

Note: This is a release candidate not intended for standalone use. This module is consumed via replace directives for its major dependencies (go-libp2p, go-libp2p-pubsub), so this release primarily exists to pin versions for downstream consumers.

v0.7.0

v0.7.0 release brings high-performance dynamic Tail maintenance for Syncer, also known as header pruning.

Notable Changes

Syncer

These new fields were introduced to Syncer's config:

	// PruningWindow defines the duration within which headers are retained before being pruned.
	// Default is 337 hours.
	PruningWindow time.Duration
	// SyncFromHash is the hash of the header from which Syncer should start syncing.
	// Zero value to disable. Value updates up and down the chain are gracefully handled by Syncer.
	//
	// By default, Syncer maintains PruningWindow number of headers. SyncFromHash overrides this default,
	// allowing any user to specify a custom starting point.
	//
	// SyncFromHash has higher priority than SyncFromHeight.
	SyncFromHash string
	// SyncFromHeight is the height of the header from which Syncer should start syncing.
	// Zero value to disable. Value updates up and down the chain are gracefully handled by Syncer.
	//
	// By default, Syncer maintains PruningWindow number of headers. SyncFromHeight overrides this default,
	// allowing any user to specify a custom starting point.
	//
	// SyncFromHeight has lower priority than SyncFromHash.
	SyncFromHeight uint64

Store

• store.Store.DeleteTo method (#275)
• store.Store.OnDelete method, which allows users to register individual header deletion handlers. This will enable users to execute farewell logic when headers are removed, e.g., cleanup data committed in the header but stored separately. (#320)
• Unsafe store recovery tools (#325)

Breaks

• store.Store.Init and store.Init were removed. Initialization is now performed lazily using the first header given to store.Append (#274)
• Temporary replaces go-datastore until ipfs/go-datastore#238 is merged upstream
  • Add the following to fix your go.mod
    replace github.com/ipfs/go-datastore => github.com/celestiaorg/go-datastore v0.0.0-20250801131506-48a63ae531e4
