- 05/25/2005 (CsG) Added more vias near the top fet Q4 and Q6, and one more via added near Q7 pin 1, 2, 3
- 05/16/2005 (CsG) Change the resistor R16 value from 100K to 120K(this is for softer 12V startup). 
- 05/16/2005 (CsG) Change the capacitor C26 value from 0.1uF/16V X7R/X5R la 0.22uF/16V X7R/X5R
- 05/12/2005 (CsG) Minor changes in cooper poor zone designs
- 05/12/2005 (CsG) Added more vias near the GND solder rings (VIN and HDD) on the both pcbs
- 05/12/2005 (CsG) Increased ring size for easier soldering for the trough hole parts(wire harness, header 8).
- 05/12/2005 (CsG) Added C26=0.1uF/16 0603 20% 25V X7R
- 05/12/2005 (CsG) Added R16=100K 0603 100kR 5% 1/16W
- 04/17/2005 (AB)  Change R4 from 470R to 680R, green LED is too bright.
- 08/11/2005 (CsG) Initial version
- 12/12/2005 (ITU) FCC / CE Certification
- 09/16/2005 (AB)Provided 330uF as replacement for 470uF, same ESR
- 09/09/2005 (Small Production Run, 10K)
- 08/08/2005 (CsG) Modified connection, C26 was tied to GND but now it is connected to VIN in order to have correct startup sequence
- 10/04/2006 (AB) C26 is now 0.22uF instead of 0.1uF. 
- 10/01/2007 (AB) Replaced one HDD with SATA (cable harness change)
- 08/08/2007 (AB) 5VSB SS is now 10nf, 3.3V SS is 8.2nf (fixes race condition for EPIA-M10K / etc auto-startup upon power loss)
- 06/28/2009  Placed mini-FIT-JR 4 pin male/female pair in line with input power cord. This will allow OEMs to easily connect to a variety of power sources while maintaining 5/2.5mm barrel connector compatibility. 
- 06/28/2009 Extended availability for the next 5 years
- 10/20/2012 Replaced obsolate Fairchild FDS6679 with FDS6679AZ, change R16 to 82K to match 12V ramp-up.
- 01/23/2013 Extended availability for the next 5 years.
- 06/15/2013 AO4420 is now EOL. Replaced with  with AO4476A
- 06/25//2013 Extending availability for the next 5 years
- 03/10//2016 Extending availability for the next 5 years
- 10/10//2020 Extending availability for the next 5 years
