Proxmark3 v4.9237 Released

This is the “Ice Coffee” release, an early foundational tagged build of the Iceman (RfidResearchGroup) fork of the Proxmark3 firmware and client. It establishes the formal release tooling for the fork and adds version reporting, build flexibility, and new reference traces.

Highlights

  • Introduced a make release process and a RELEASE_NAME, formalizing how tagged releases of the fork are produced from a clean master.
  • Added version information to the client and color-coded ARM and FPGA version sections so users can verify firmware and client are in sync.
  • Added CROSS_CFLAGS and related CROSS_*FLAGS to ease cross-compilation, with accompanying documentation.
  • Enabled -Wconversion in the extra compiler flags and cleaned up the resulting type-conversion warnings for safer builds.
  • Fixed lf nexwatch clone to use only 12 bytes, correcting NexWatch tag cloning.
  • Made trace load error out cleanly when run in offline mode instead of misbehaving without a device.
  • Added new HF 15 traces and an Oyster MDES trace as reference captures, plus Android work-directory support for the mobile client.
