Release PromptBranch v0.2.1 · PromptBranch/promptbranch

PromptBranch Desktop v0.2.1

This desktop-only patch release improves multi-device sync reliability and Linux
package compatibility. CLI and MCP package versions are unchanged.

PromptBranch now chooses the sync listening port once, remembers it across
restarts, and shows it under Settings → Sync.
Added the ability to change the listening port manually, with validation,
visible listener errors, and clearer address-pairing and firewall guidance.
Fixed repeated disconnect/reconnect loops by making simultaneous connections,
TLS handoff, stale-connection retirement, saved-route reconnection, and retry
ownership deterministic.
Improved pairing and lifecycle cleanup: expired prompts close automatically,
overlapping attempts are handled safely, and sync networking drains before
the app closes or restarts it.
Hardened Bonjour/mDNS discovery so discovery failures and changing network
routes do not interrupt the wider sync service or discard a working manual
route.
Corrected packaged macOS executable identity so Local Network permission is
associated with PromptBranch rather than the stock Electron executable.
Updated Linux DEB dependencies for Ubuntu 24.04 and other distributions using
libasound2t64, while retaining compatibility with systems providing
libasound2.
Updated the sync documentation for visible/configurable ports, manual pairing,
firewalls, and port conflicts.
