# Proxmark3 v4.17511 Released

> This Iceman fork release adds NTAG424 command support, gen4 (GDM) magic-card tooling, UDP and IPv6 connectivity, and a reworked JSON dump format.

_2023-11-13_

Version 4.17511 of the Iceman fork of the Proxmark3 firmware and client adds support for NTAG424 tags, gen4 magic-card management, new network transport options, and a modernized JSON dump format across many protocols.

## Highlights
- Added NTAG424 support, including `info`, encrypted ReadData/WriteData comms, and refactored MAC and IV calculations for working with these tags.
- Reworked the client JSON dump format for `hf 14a`, `hf 14b`, `hf 15`, cryptorf, lto and NDEF, deprecating the EML format for saving while keeping EML loading.
- New gen4 (GDM) magic-card commands: `ginfo`/`gen4 info` for low-level config decoding plus a change-password command, making these magic cards easier to inspect and manage.
- Added UDP and IPv6 connectivity for the client (TCP/UDP on Linux and Windows), with bind options, a ring buffer and the CLI prompt now showing the active transport.
- New `hf iclass creditepurse` command to credit the iClass e-purse debit value, plus improved `hf iclass view`/`decrypt` SIO length detection and a ported configcard implementation for keyroll cards.
- Added HID SAM picopass communication support and an ISO14443-B smartcard relay daemon, broadening the platform's smartcard tooling.
- Added loading support for Flipper Zero MFC, MFU and .picopass dump files, plus a new `data bmap` command that breaks a hex value into labeled bit rows from a template.
- Added MIFARE Ultralight AES signature verification and identification, double-quoted argument support in the CLI, and a `-m` short flag for timeout-related commands.
