The latest update to Rust-Lightning introduces end-to-end and payer-side tests specifically for currency-denominated offers and invoices. This enhancement ensures robust coverage of the standard payment flow, including the rejection of excessive invoices and handling of unverifiable fiat invoices when conversion support is lacking. Additionally, the update addresses quantity-scaled invoice requests, thereby thoroughly exercising the main invoice amount verification paths introduced by currency-denominated offer support. This update was co-authored with AI assistance from OpenAI Codex.
