Release numbering

The Elphel software is released in several forms:

  1. - Live DVD including firmware released at the time LiveDVD was created and software to update the camera firmware to the later release using downloaded firmware image.
  2. - Source tarball on SourceForge
  3. - Binary images + installation scripts
  4. - Source code in CVS.

The software releases on SourceForge (source tarballs, binary images) have 3 dot-separated release numbers, like elphel353-7.1.5.tar.gz for the source code or image353-2.10-7.1.5.tar.gz for binary images to be copied to the camera flash memory

The most recent (and definitely "unstable") software is available on CVS at Sourceforge. The software available only from the CVS has 4 dot-separated numbers, the thirst three matching the last version released as a tarball distribution on SourceForge.

elphel353-7.2.0.pre1 (open, pre-alpha)

This is not a release, just a collection of files (drivers do not yet match FPGA and FPGA code is probably not yet operational). The new CVS tree (elphel353-7.2) is started, but please do not use it yet.
