G1 platform (DS-2CD2XX5,DS-2CD2XX3G0) FW 5.5.2 firmware versions

[aster1x]

At the DOWNLOAD PORTAL
there are 2 versions of the firmware 5.5.2.
One is named IPC_G1_EN_NEU_5.5.2_170905.zip and the other is named IPC_G1_EN_STD_5.5.2_170905.zip.

What is the difference between these two versions?

Anyone with an idea for the above post?

STD = Standard
NEU = Neutral
Not sure what they mean. But there is a newer version of the firmware: 5.5.3
