During the Stellar Developer Meeting, CAP 67 is discussed, focusing on standardizing the format of events for Stellar operations to align with the Stellar Asset Contract. The proposal includes eliminating the admin topic from mint and clawback events, addressing classic payment semantics, and introducing a fee event that reflects the fee paid by the source account. Additionally, the conversation touches on the introduction of SD address types for representing claimable balances and liquidity pools to improve tracking. The meeting further explores TTL updates and the need to adapt to parallel transaction execution via CAP 63. These changes aim to enhance the functionality and reliability of Stellar operations and maintain user-friendly interfaces within the Stellar ecosystem.
