AsProgrammer dregmod v5 – Patch Notes / Changelog
(Released 20 August 2026)

latest New Features

• Full Bus Pirate v5, v6 and v7 support (native BPIO2 protocol) via a new BusPirateV5+ menu
  → A 64 Mbit SPI flash now reads in ~40 seconds at 8 MHz
• Bus Pirate v3.x performance boost — up to 8× faster
  → Serial link speed can now be raised up to 2 Mbaud (64 Mbit flash reads in ~1.5 minutes instead of 13)
• No more external DLL — buzzpirathlp.dll completely removed (everything is now pure Pascal)
• New I2C bus scanner with address map + quick “Use this address” button
• Live COM port list (auto-refreshes when you plug/unplug devices)
• Device info / voltage window (shows firmware version, hardware revision, measured voltages, short detection on Buzzpirat)

Improvements & Fixes

• Corrected SPI clock table for Bus Pirate v3 (previous “8 MHz” was actually ~2.6 MHz)
• Responsive GUI while Bus Pirate operations are running
• Better error handling and stability across all programmers
• Legacy mode still available for Bus Pirate v5+ (emulates v3 for flashrom compatibility), but BPIO2 is strongly recommended (≈20× faster)
