Subject Re: What's the difference between release 1.1.1, 1.2.0 and 3.0.0?
Date Wed, 28 Nov 2012 05:54:37 GMT
Hi Harsh´╝î

Thanks very much for your detailed explanation!

For 1.x line, we really want to know which release could be used by us, so
have further questions:
- Is 1.2.0 more advanced that 1.1.1?
- Do we have general release time of above two releases?

For 2.x line:
- Will its stable release contain all fixes and features of 1.x line?
- Can we know the general release time of the coming stable release of 2.x
line?
