New COLDCARD EDGE Release: Versions 6.3.4X (Mk4) and 6.3.4QX (Q).

Bugfix Release

This bugfix release fixes a potentially serious policy deserialization bug affecting versions 6.2.2X, 6.3.3X, and 6.3.3QX. The bug is limited to policies where key placeholders are not in strictly ascending order. This bug will prevent you from using your miniscript wallet BUT in no case can put your funds in any danger. Also there is no need to regenerate backups as those are correct. All users of above mentioned Edge firmware versions should upgrade to this new firmware to patch the issue. Thanks to pythcoiner and Liana team for finding and reporting this issue.

Another relevant bug discovered prevented EDGE users from importing miniscript policies with just single key and timelock. 6.3.3X(Q) is synced with 5.4.0 and 1.3.0Q releases (contains all changes from that version.

What is EDGE?

Branch new_edge is our long-lived branch that contains features that may not be ready for prime time, such as Taproot and Tapscript, BSMS and Miniscript.

Our standards for releasing new Edge versions are lower, so we can iterate faster and get these advancements out to other developers as soon as possible.

Edge releases typically contain all the latest Mk4/Q features from our most recent mainstream firmware.
