Re: [Quantlib-dev] QuantLib 1.0 beta 1 available

[Dirk E. <ed...@de...>]

My $0.02:  'triplets' give us more rope for intermediary releases like 1.0.1,
1.0.2, etc.  If you as release manager don't plan to do those but rather want
to jump to 1.1, 1.2, 1.3 -- fine.   I'd say that the empirical evidence
across open source projects is in favour of 'triplets', but hey, beauty is in
the eye of the beholder.  Your call.  We all will just whine.

Here is what my Debian box has:

edd@ron:~> ls -ltr /usr/lib/libQuantLib*
-rw-r--r-- 1 root root 12042164 2009-10-11 07:02 /usr/lib/libQuantLib-0.9.7.so

We keep just the .so of older release; code built against those stills
runs. Libtool (which I still know too little about) in its magic uses three
values anyway so we have the 'active' version libQuantlib.so.0.0.0 with two
softlinks use while building code.  I think that major number ought to be '1'
as in 

   /usr/lib/libQuantLib.so.1 -> libQuantLib.so.1.0.0

to signal the long-awaited API freeze for 1.0.  No?

With that I'd also make the Debian package name 'libquantlib1-dev' rather the
current 'libquantlib0-dev'.  But that is all cosmetic at then end of the
day.  What mattered is that we have distinct packages allowing distinct
versions to co-exist:

edd@ron:~> dpkg -l | grep libquantlib-
ii  libquantlib-0.9.7       0.9.7-1+b2              Quantitative Finance Library -- development package
ii  libquantlib-0.9.9       0.9.9-3                 Quantitative Finance Library -- development package
ii  libquantlib-1.0.0       1.0.0~20100112-1        Quantitative Finance Library -- development package
edd@ron:~> 

And whether that is libquantlib-1.0.0 or libquantlib-1.0 doesn't really
matter.  Apart from the fact that I created precedent (:-/) but I can always
fall back in line for libquantlib-1.1 if you really really howl.

| Right. Please go ahead.

Will do if I get a few moments.
