Yes V5 got V5.0, 5.2, 5.3 and 5.4 as per Segger documentation.

I got the following info from Segger documentation, the old doc
documented up to 5.2. The new documentation does not mention
V1 - v4, just saying that they are obsolete.

Differences between different versions
Versions 1-4 (obsolete)
These J-Links use a 16 bit CISC CPU. Maximum download speed is app.
150 kB / sec.

JTAG speed
Maximum JTAG frequency is 8 MHz; possible JTAG speeds are:
8 MHz / n, where n is 1,2, ..., resutling in speeds of:
8.000 MHz (n = 1)
4.000 MHz (n = 2)
2.666 MHz (n = 3)
2.000 MHz (n = 4)
1.600 MHz (n = 5)
1.333 MHz (n = 6)
1.142 MHz (n = 7)
1.000 MHz (n = 8)
Adaptive clocking is not supported.

Version 5.0
Uses a 32 bit RISC CPU. Maximum download speed (using DCC) is over 650 kB / sec.

JTAG speed.
Maximum JTAG frequency is 12 MHz; possible JTAG speeds are:
48 MHz / n, where n is 4,5, ..., resutling in speeds of:
12.000 MHz (n = 4)
9.600 MHz (n = 5)
8.000 MHz (n = 6)
6.857 MHz (n = 7)
6.000 MHz (n = 8)
5.333 MHz (n = 9)
4.800 MHz (n = 10)

Target Interface
nTRST is push-pull type
RESET is push-pull type

Version 5.2
Uses a 32 bit RISC CPU. Maximum download speed (using DCC) is over 650 kB / sec.

JTAG speed.
Possible JTAG speeds are identical to these of version 5.0.

Target Interface
nTRST is push-pull type
RESET is open drain

Version 5.3
Identical to version 5.2 with the following exception:
• 5V target supply current limited
5V target supply (pin 19) of Kick-Start versions of J-Link is current monitored
and limited. J-Link automatically switches off 5V supply in case of
over-current to
protect both J-Link and host computer. Peak current (<= 10 ms) limit is 1A,
operating current limit is 300mA.

Version 5.4
Identical to version 5.3 with the following exception:
• Supports 5V target interfaces.

Version 6.0
Identical to version 5.4 with the following exception:
• Outputs can be tristated (Effectively disabling the JTAG interface)
• Supports SWD interface.
• SWD speed: Software implementation. 4 MHz maximum SWD speed.
• J-Link supports SWV (Speed limited to 500 kHz)

Version 7.0
Identical to version 6.0 with the following exception:
• Uses an additional pin to the UART unit of the target hardware for SWV support
(Speed limited to 6 MHz).

Version 8.0
Identical to version 7.0 with the following exception:
• SWD support for non-3.3V targets.
