Upgrade Guide

Upgrading to 0.9.8

No breaking changes. All changes are backward compatible:

  • bd daemon: New optional background service for auto-sync workflows
  • bd sync: New optional git integration command
  • bd compact: New optional command for issue summarization (requires Anthropic API key)
  • --format flag: Optional new feature for bd list
  • Label/title filters: Optional new filters for bd list
  • Bug fixes: All critical fixes are transparent to users

Simply pull the latest version and rebuild:

go install github.com/steveyegge/beads/cmd/bd@latest
# or
git pull && go build -o bd ./cmd/bd

Note: The bd compact command requires an Anthropic API key in $ANTHROPIC_API_KEY environment variable. All other features work without any additional setup.

Upgrading to 0.9.2

No breaking changes. All changes are backward compatible:

  • --deps flag: Optional new feature for bd create
  • external_ref: Optional field, existing issues unaffected
  • Metadata table: Auto-migrates on first use
  • Bug fixes: All critical fixes are transparent to users

Simply pull the latest version and rebuild:

go install github.com/steveyegge/beads/cmd/bd@latest
# or
git pull && go build -o bd ./cmd/bd

Upgrading to 0.9.1

No breaking changes. All changes are backward compatible:

  • Auto-migration: The dirty_issues table is automatically added to existing databases
  • Auto-flush/import: Enabled by default, improves workflow (can disable with flags if needed)
  • ID partitioning: Optional feature, use --id flag only if needed for parallel workers

If you're upgrading from 0.9.0, simply pull the latest version. Your existing database will be automatically migrated on first use.

Upgrading to 0.9.0

No breaking changes. The JSONL export format is backward compatible.

If you have issues in your database:

  1. Run bd export -o .beads/issues.jsonl to create the text file
  2. Commit .beads/issues.jsonl to git
  3. Add .beads/*.db to .gitignore

New collaborators can clone the repo and run:

bd import -i .beads/issues.jsonl

The SQLite database will be automatically populated from the JSONL file.
