# Proxmark3 v4.18341 Released

> This Iceman fork release adds an ID48 key-recovery library, new `lf em 4x70 autorecover` and `hf mfu wipe` commands, and reworked `hf mf dump` and `hw tune` output.

_2024-03-20_

Version 4.18341 of the Iceman fork of the Proxmark3 firmware and client is out. This update focuses on new EM4x70 tooling, an ID48 key-recovery library, fresh MIFARE Ultralight wiping support, and a batch of client output and detection improvements.

## Highlights
- Added an `id48lib` library with EM ID48 key-recovery support, giving the client a foundation for cracking ID48 credentials. The bulky 128k lookup table was dropped in favor of the library implementation.
- New `lf em 4x70 autorecover` command automates EM4x70 key recovery, and the related commands were renamed to `setpin` and `setkey` for clarity.
- New `hf mfu wipe` command zeroes a MIFARE Ultralight tag while preserving UID, lock and OTP blocks, making cards easier to reset for reuse.
- Reworked `hf mf dump` so it now prints the dumped memory after saving, matching the behavior of the other `dump` commands in the client.
- `hw tune` was moved into its own command file and its output was reworked, while the redundant `data tune` command was removed.
- Added `hf 14b restore` plus reworked 14b reader and `wrbl` handling, improving ISO14443-B card writing and recovery.
- Improved MIFARE Classic magic-card detection and hint reporting in `hf mf info`, plus added the CEPAS AID to the client AID list for better card identification.
- The `hf search` plot window is now hidden by default during searches so the plot is captured without popping up a window unless you opened it first.
