Releases and Updates

I mentioned last week that Stellar Core v12.5.0 was coming soon and I would never lie to you. v12.5.0 is out now and it includes a number of new features including new SCP metrics, improved catch-up logging, SCP code cleanup and more. Make sure to update to the latest version!

In other news, CAP-0015: Fee Bump Transactions has been implemented and will be included in Protocol 13 (discussed in issue #34). If you’re unfamiliar with CAP-0015, the short explanation is that it allows an arbitrary account to pay the fee for a transaction.

This means that in the event a pre-authorized transaction (e.g. the release of escrow funds) cannot be executed due to an increases in fees, someone can use a fee bump transaction to increase the fee and resolve the issue.

Additionally, this will allow services to directly pay for their users’ fees if they so choose. Currently, services have to send their users lumens and hope they use them for fees — a clunky experience. CAP-0015 will provide an elegant solution to this problem and improve this area of the user onboarding experience.

Last but not least, horizonclient (a Stellar Go SDK package) v2.2.0 and JavaScript Stellar SDK v4.1.0 are both released and ready for use. These two releases add SEP-0029 support which describes a standard way to check if a memo is required before sending a transaction.
