question about released version id

[鞠適存 <ch...@gmail.com>]

hi,

I wonder how to make the hadoop version number.
The HowToRelease page on the hadoop web site just describes
the process about new release but not mentions the rules on
assigning the version number. Are there any criteria for version number?
For example,under what condition the next version of 0.18.0 would be call as
0.19.0, and
under what condtion  the next version of 0.18.0 would be call as 0.18.1?
In addition, did the other Apache projects (such as hbase) use the same
criteria to decide the
version number?

Thank you in advance for any pointers.

Thanks a lot, Owen and Rasit.
Is there any rule for deciding incompatible API changes will be put into
trunk or branch?
The criterion is "time" or "importance of these changes" or "number of these
chnages" or others?

Each 0.18, 0.19 and 0.20 have their own branch. The first release on  
each branch is 0.X.0, and then 0.X.1 and so on. New features are only  
put into trunk and only important bug fixes are put into the branches.  
So there will be no new functionality going from 0.X.1 to 0.X.2, but  
there will be going from a release of 0.X to 0.X+1.

Hi, here is the versioning methodology of Apache Portable Runtime,
But I think hadoop's is much or less the same..
