# COLDCARD Mk4 Firmware v5.1.2 release
- Support all SIGHASH types (previously only SIGHASH_ALL was supported). This can enable specialized Bitcoin transactions involving multiple signers and even limited changes to the transaction after signing. To enable the most dangerous SIGHASH modes, you must change Advanced -> Danger Zone -> Sighash Checks. Warnings are shown for all of the new SIGHASH modes regardless of this setting.
- SeedXOR now supports 12 and 18 words mnemonics.
- Signing memory, speed optimizations.
- Docker repro build container improvements (non-privileged container)
- Bugfix: After extended private key and TAPSIGNER backup import into blank wallet, users needed to manually reboot Coldcard.
- Bugfix: Do not set SIGHASH type on foreign PSBT inputs
- Bugfix: "Validating..." screen would be shown twice in some cases. Improves signing performance.
