ACINQ/eclair v0.2-beta6

Eclair v0.2-beta6

on GitHub

This is a maintenance release of eclair, which includes several improvements and bug fixes, including:

• improved reporting, more readable and parseable logs, with a default rolling policy (one log file per day)
• support for channel range queries, a feature which will speed-up routing table synchronization. This is an important feature for light nodes (mobile nodes, ...)
• an audit database which keeps tracks of received/sent/relayed payments and miners fee, and new audit, networkfees and channelstats API calls
• a "smooth" fee rate estimator, which will prevent channels from being closed when onchain fees change suddenly and peers don't agree on onchain fee rates
• temporary bans of peers that send too many bad routing info items (such as channels announcements for channels that have already been closed)

We strongly recommend that users upgrade their nodes.

Upgrading

This release is compatible with Eclair v0.2-beta5. You don't need to close your channels, just stop eclair, upgrade and restart.
