SME 6.5, current status "RC2" Release Code2 is developed on RH7.3legacy (org. 2001/ -2)
- main programmer ShadLords's intention most likely was to "tighten up" some issues since RH7.x,8,even RH9 are out of RH support already)
SMESERVER 7.0, current status "alpha3" is developed on Centos 3.4 which is "the free" version of RedHeadEnterprise3.x (comment valid only for non lawyers !) (org. 2004/-5)
- main programmer Charlie Brady (MITEL/e-smith)'s "private" work edition is on the ibiblio developers download section. MITEL will not publish a new "unsupported" version as they have publically stated quite often. This version is alpha code, main intention obviously is to get SME to the year 2005. Release will supposedly contain Centos 4.0 /RHEL4. ShadLords is also working on a Centos release at his home page.
IMO there is little to compare so here's my outlook:
"6.5" is patched up legacy code ... but good work from a dedicated developer (Thanks Shad)
"7.0" is alpha still but very promising, hopefully it will be the future of SMESERVER - running on new hardware (SATA) with a current kernel - (Thanks Charlie)
From the above you may guess I am going to skip 6.5 (no need for me), have tested 7.0alpha3 quite successfully and hope to start using it with the next hardware I (privately) buy.
