# Proxmark3 v4.18218 Released

> A large Iceman fork release with a major ISO15693 overhaul, new `hf_15sim` standalone mode, `data crypto`, `hw readmem` flash dumping, and reworked ISO14443-B comms.

_2024-02-18_

Version 4.18218 of the Iceman fork of the Proxmark3 firmware and client is a large update. It overhauls ISO15693 and ISO14443-B handling, adds new simulation and crypto tooling, and introduces processor flash memory dumping along with many new commands and detection improvements.

## Highlights
- Major ISO15693 refactor: `hf 15` commands now use NG packets, `hf 15 raw` supports `-k` keepfield and `-s` select, and dump/rdbl/rdmulti handle 4 or 8 byte block sizes with unified error handling. A new `hf 15 wipe` command zeros card memory.
- New `hf_15sim` standalone mode simulates an ISO15693 tag with support for many commands including `GET_RANDOM_NUMBER`, `ENABLE_PRIVACY` and `SET_PASSWORD`, plus a new `jfs15_v4` JSON dump format.
- Reworked ISO14443-B comms over NG packets, with overhauled APDU handling, tearoff support, a `force` option for `hf 14b sriwrite`, and new picopass ISO14443-B anticollision.
- Added the `data crypto` command backed by a new libpcrypto, bringing client side cryptographic operations.
- New `hw readmem` command (and `--dumpmem`) reads, views and writes processor flash memory to file, with boundary checks against addressable space.
- New `lf` view and demod commands: `lf em 4x05 view` with config-word bit breakdown, `lf em 410x demod --bin`, `lf idteck demod`, and `lf hitag view`/`eview` for dump files.
- Added GD library support so the Waveshare ePaper command can convert, crop and scale images offline, with the dependency wired into CMake and CI.
- Added rudimentary MIFARE Ultralight AES authentication and signature verification, plus `hf mfu amii` for decrypting and encrypting Amiibo dumps and card memory.
- Dense output mode (`-z`) added across `hf mfu`, `hf 15`, `hf xerox` and `hf 14b` dump/view commands, plus backported security fixes from liblua 5.2.4.
