library versioning

to the list)

Hi,

Can someone reiterate our versioning scheme for libraries? I'm a bit 
confused because there seem to be some contradictions.

- v4-11 branch has talloc v2.2.0 and master has v2.3.0 (additions to ABI 
- 2.3.0 was released without a Samba version that uses it)
- Due to a bugfix, master goes to talloc 2.3.1 and Metze suggests that 
v4-11 should also go to 2.3.1 (and I remember that indeed this is the 
way it used to work)

Now trying to apply same logic to ldb:
- v4-11 branch has ldb v2.0.7 and master has unreleased v2.1.0 
(additions to ABI)
- In the same way, I suppose that we need to release ldb 2.1.0 and 
upgrade v4-11's ldb to 2.1.0. But in ldb, we have 2.0.6 and 2.0.7 which 
are bugfix versions off v4-11 branch - why did we publish bugfix 
versions off v4-11 instead of releasing 2.1.x and moving v4-11 to use that?

Thanks,
Uri.
