Use bitcoin-lib 0.48 (#3316)

This commit updates Eclair's underlying Bitcoin library from version 0.47 to 0.48 and makes small code adjustments to match the new library's API. The changes touch how private keys are derived and how test data is converted. There is no d…

Add support for zero-fee commitment format (#3192)

This commit adds an experimental new Lightning channel type to Eclair called 'zero-fee commitments.' It is a large feature patch implementing a draft BOLT specification (PR 1228), not a fix for a known vulnerability. The change introduces …

Fix flaky DER signature weight test (#3299)

Store our closing_complete in the simple close session (#3289)

This commit changes how Eclair (a Bitcoin Lightning node) remembers its own closing signatures during a mutual channel close. Previously, the code re-generated signing nonces and re-signed closing transactions when the peer's signature arr…

This commit removes support for older Lightning channel types ('static_remotekey' and 'default' channels) from the Eclair node software. It is a deliberate feature-removal change announced in the previous release. The main risk is operatio…

Removal of legacy commitment format support reduces attack surface for fee-manipulation and transaction-malleability issues present in pre-anchor channels.Simplified fee tolerance removes the 'too low' feerate check, relying on anchor/taproot CPFP/RBF behavior.Explicit channel_type requirement prevents silent downgrade to weaker channel types.
