Difference between advanced ip services k9 image and ip services k9 image?

[murray-davis]

I am looking at upgrading the IOS on all our switches. A couple of the switches that we have are 3750G-12S-E switches that have the advanced IP services k9 image: 12.2.37. I noticed in the download site, version 12.2.44 still shows the advanced IP services k9 image, but 12.50 and 12.52 only show ip services k9 image. Is this just a change in Cisco's naming convension or is the advanced IP services k9 image just not available? I specify k9 since I want the cryptograpic image.

Just a change in the naming starting with 12.2(50)SE.

The Advanced IP Services feature set is now EOL
