[Stefan Vigerske]

Hi,

I just created a new Ipopt maintenance release.

Here is a list of changes (r1234 stands for a related svn changeset, 
#123 for a ticket number in the trac bugtracking system):

- fix compilation issue of Java interface on systems where Index and
   jint have different size [r2498, #241]
- work around failing check for random number generator with gcc 4.8.3
   [r2495, r2496]
- readded IpTaggedObject.cpp to list of sources to compile in MSVS
   v8-ifort project file [r2492]
- work around missing support for thread-local storage with gcc < 4.5
   on MacOS X [r2491, #243]
- fix call to MKL Pardiso init function [r2489]
- speed up Triplet to CSR converter [r2487, #234]
- fixed a bug in equilibration scaling where average values were
   computed incorrectly (by V. Zverovich) [r2483]

The source tarballs should be available tomorrow.

Enjoy,
Stefan
