"=X/|X Converts X/reverse X" no longer works:

[USBEprom]

By testing "=X/|X Converts X/reverse X" with firmware U_1-29092019.hex and S_1-29092019.hex I built (http://dangerousprototypes.com/forum/index.php?topic=8498.msg70165#msg70165) I found that it no longer works:

Bus Pirate v3.5
Community Firmware v7.1 - goo.gl/gCzQnW [HiZ 1-WIRE UART I2C SPI 2WIRE 3WIRE KEYB LCD PIC DIO] Bootloader v4.5
DEVID:0x0447 REVID:0x3046 (24FJ64GA00 2 B8)

0x01 = 1 = 0b00000001
HiZ>=0x89
0x00 = 0 = 0b00000000

As far as I can understand from the repositories I have archived, the problem starts with releases S_1-28102018.hex and U_1-28102018.hex.

"=X/|X Converts X/reverse X" in all the firmwares released later do not work properly.
