The v3 (aka classic or trunk) is just a synonym for 6502 format images. 
It does not refer to the release version.

Squeak (the product) has three components, each with their own "version" 

  * virtual machine (arch dependent). Use "-version" argument to get version
  * virtual image file (arch independent). See ckformat below
  * live object graph (arch independent). This graph is constructed in 
memory from the image file and is associated with an update sequence 
number. See "about squeak" to get this number.

The format number describes the encoding of object graph in an image 
file. Use the ckformat executable to get this number.

  $ ckformat Squeak5.2-18225-64bit.image

E.g. Squeak5.2-18225-64bit.image is a Squeak 5.2 release with an update 
sequence number of 18225 and a format number of 68021 with 64 bits per 
word (aka spur64).
