COLDCARD Software Updates
Mk4’s Firmware version 5.0.3 has many updates, most notably for Taproot advocates. Folks will be happy to know that P2TR and Bech32m are now deployed on COLDCARD MK4 as of 5.0.3. For the older Mk3, we have recently shipping an update, Mk3’s 4.1.5, with the same P2TR features.
And then… on Friday we released 5.0.4 for Mk4! It has numerous improvements focusing on the needs of Bitcoin developers, such as support for RegTest (for use on your own Regression Testnet coins) and major upgrades to our testing setup. From outside contributors, we have improved encryption for HSM users, documentation fixes, and better reproducible builds.
Yes! THREE releases in just one month!
