Sparrow v1.7.7: High Fee Environment Improvements & More

Sparrow v1.7.7 has been released with:

• Improved mempool fee rates chart.
• Multiple improvements for a high fee environment.
• Performance optimizations for large wallets.
• Better usability on @BorderWallets grids.

What's new

• "The mempool fee rates histogram on the Send tab has been revamped in this version, featuring finer granularity and the same color scheme used by @mempool. Clicking on the chart expands it, and offers a 24h view."
• "There are a number of other improvements related to transacting in a high fee environment, such as better error messages when broadcasting with an insufficient fee, and adding additional inputs to an RBF transaction if needed as the required fee is increased."
• "This release has several optimizations, including much improved performance on very large wallets with high address reuse, and a lighter load on low powered nodes when connected to Bitcoin Core."
• "The @BorderWallets grid UX has been improved to display the order of word selection and disallow simultaneous multiple selection. There is better @TAPSIGNER support too with the ability to import custom derivation paths and easier backup."
• "QR scanning is improved with support for inverted QRs and other formats."
• "There are many further enhancements too - see the release notes for details."
