Display: - Long bech32/bech32m addresses were cut at the first 42 characters on the verify screen, so the QR code and the text disagreed about where funds were going. Addresses now wrap across the full screen, and Zcash unified addresses get a dedicated text-first confirmation layout. - Font, draw and layout helpers gained the measurement and wrapping support those screens need. ROM: - Device snprintf/vsnprintf are redirected to newlib's integer-only engine (see cmake/caches/device.cmake), which removes the float formatting path, soft-double libgcc and its malloc dependency from the image. Percent and amount rendering that used %f is reworked to integer formatting, so THORChain withdraw percentages and send amounts still display exactly as before — Gate-3 frames under docs/security/evidence/rom-printf-integer-percent. - keepkey.ld asserts the 16 KiB stack reserve the SRAM budget gate measures.

Superseded by the smaller audit-ready 7.15 stack: #359 release foundation, #360 authenticated clear-signing, #361 recovery and entropy, #362 Zcash Orchard, #363 chain integrations, and #364 Bitcoin/release security. All release changes remain preserved in the replacement branches and preservation tags. The replacement aggregate was tree-verified against the prior release and passed the local CI-equivalent container suite (405 firmware, 2 board, 18 crypto, and 7 Pallas constant-time tests). GitHub-hosted checks have been explicitly dispatched and are currently queued. |
