+24 Nov 11:
+
+- Significantly rearranged Divonne, e.g. unrolled the recursion
+ on regions, for better parallelizability.
+
+- Improved parallelization through DoSample.
+
+- Automatic detection and usage of the free cores on a machine,
+ or else set CUBACORES to the number of cores one wishes to
+ utilize, with negative numbers meaning "up to" depending on
+ availability (e.g. -2 means "use up to two free cores").
+
+
+12 Aug 11:
+
+- Version 3.0: Added parallelization, currently 'only' through
+ the DoSample routine. Uses fork/wait so integrands do not have
+ to be reentrant.
+
+ Specify number of cores in environment variable CUBACORES.
+ C/C++/Fortran only, Mathematica users need to replace MapSample
+ by ParallelMap or similar (as before).
+
+
+18 Jun 11:
+
+- Fixed problem with inner integration bounds depending on outer
+ ones in the MathLink executables.
+
+
+15 Feb 11:
+
+- Moved partview to Qt 4.
+
+- Rectified error reporting via longjmp, in particular avoiding
+ sending $Failed twice in MathLink which would upset the
+ following communications.
+
+
+13 Sep 10:
+
+- Added iteration number to integrand's optional parameters
+ (Vegas and Suave).
+
+- Fixed initialization problem when using state file in Vegas.
+
+- Added tests for MathLink to configure.
+
+
+20 Jul 10:
+
+- Fixed severe bug in divonne/Split.c (wrong sign in SignedDelta
+ macro).
+
+
+14 Jul 10:
+
+- Disabled optimization for gcc 4.2.x and 4.4.3, which would lead
+ to an Internal Compiler Error when compiling Cuba, see
+ http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40237
+ http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42956
+
+
+21 Jun 10:
+
+- Fixed problem with bashy syntax in tools/mcc.
+
+
+8 Jun 10:
+
+- All Cuba functions now reentrant, except for gridptr_ and griddim_
+ in Vegas, which are intentionally preserved across calls.
+
+
+19 May 10:
+
+- Version 2.0: Changed invocations.
+
+- Added void *userdata to be passed to integrator.
+
+- Promoted integrand to int function, has to return 0 if successful,
+ otherwise integrator terminates immediately.
+
+- Moved all global variables (common blocks) to argument list.
+
+
+12 Feb 10:
+
+- Added Ranlux pseudo-random number generator.
+ Luxury level 0 (mis)used for Mersenne Twister branch
+ (but observe that Luxury level 24 = Luxury level 0).
+
+- Changed external variable mersenneseed to
+ struct { unsigned int level, seed; } cubarandom;
+
+
+22 Jul 09:
+
+- Fixed potential segfault in Split.c of Divonne, thanks to
+ Andreas v. Manteuffel.
+
+
+29 May 09:
+
+- Added flushing of grids in Vegas through a negative grid number.
+
+
+25 May 09:
+
+- Removed explicit pointer reference from reallocatable
+ "region_" array.
+
+
+8 May 09:
+
+- Improved memory handling in Divonne.
+
+
+8 Apr 09:
+
+- Version 1.6: Improved memory handling in Cuhre.
+ Thanks to Valery Yundin for pointing out the problem.
+
+
+6 Mar 09:
+
+- Fixed segfault in Divonne if all samples from a region returned NaN.
+
+- Reinstated fcc to fix static linkage problem with mcc 7.
+
+
+10 Feb 09:
+
+- Removed dependence on fcc script.
+
+
+19 Jan 09:
+
+- Added missing #include <stdlib.h> to partview.cpp.
+
+
+15 Jan 09:
+
+- Fixed problem with MathLink compilation for Mathematica 7.
+
+
+5 Dec 08
+
+- Version 1.5: Added possibility to set Mersenne Twister
+ random seed.
+
+- Introduced function MapSample to map the integrand over
+ the points, whose default value Map can be replaced e.g.
+ by ParallelMap.
+
+
+15 Feb 08
+
+- Added further check to Suave for sharp-edged functions.
+
+
+15 Jan 08
+
+- Fixed bug in makefile.in w.r.t. DESTDIR.
+
+
+2 Jan 08
+
+- Fixed minor bug in invocation of IniRandom in Suave.
+
+
+19 Dec 07
+
+- Version 1.4: Added new flag (bit 4), to turn off smoothing of
+ the importance function for sharp-edged functions.
+
+- Improved configure for Cygwin. Now compiles MathLink
+ executables `out of the box'.
+
+
+30 Nov 07
+
+- Fixed detection of variable-size arrays in configure.ac.
+
+- Minor fixes for autoconf 2.60.
+
+
+30 Aug 07
+
+- Added passing of weight information to the integrand routine
+ in Vegas and Suave. Mathematica versions use $Weight.
+
+
+7 Mar 07
+
+- Documented the ll versions in the manual.
+
+
+1 Mar 06
+
+- Version 1.3: added long long int versions, i.e. all
+ number-of-points-like quantities are now long long int
+ instead of int. The corresponding names are prefixed with
+ "ll", e.g. llVegas.
+
+
+5 Jan 06
+
+- Corrected a number of declarations so that changing the "number"
+ typedef in stddecl.h to a longer integer should work now.
+ Note that this bugfix has NO EFFECT if the "number" typedef
+ was not changed by hand!
+
+
+31 Aug 05
+
+- A small patch considerably reduces the "mysterious" problem
+ in Vegas and Suave that further iterations on a more or less
+ optimal grid would often degrade the grid.
+
+
+2 Jun 05
+
+- Added some #ifdefs to make the compile completely silent.
+
+- Changed HUGE_VAL to DBL_MAX to avoid problems with icc.
+
+
+7 Mar 05
+
+- Extended Divonne's Korobov tables.
+
+- partview now sorts the list of rectangles so that the smallest
+ ones come on top.
+
+
+2 Mar 05
+
+- Fixed "mysterious" problem where Divonne would report a
+ larger-than-requested error even though enough samples were
+ available.
+
+
+17 Feb 05
+
+- Rewrote partview.cpp with tabbed window.
+
+- Moved sources to src/{vegas,suave,divonne,cuhre}.
+ The original names would get into the way of the Mathematica
+ executables on OSX's case-insensitive file system.
+
+
+15 Feb 05
+
+- configure now disables compilation of demo-fortran if no
+ Fortran compiler is found.
+
+
+9 Feb 05
+
+- Added some explicit typecasts and other tidbits such that
+ Cuba compiles successfully also with a C++ compiler now.
+
+
+7 Feb 05
+
+- Added erf implementation in case some "C99 compliant" compiler
+ like M$ Visual C++ in fact has no erf.
+
+
+4 Feb 05
+
+- Added partview.m for Mathematica.
+
+
+3 Feb 05
+
+- Added proper autoconf configure.
+
+- Added cuba.F, a Fortran chooser which makes the invocation
+ of the Cuba routines still simpler from Fortran.
+
+- Straightened out the contexts of the MathLink executables.
+
+
+2 Feb 05
+
+- Substituted preprocessor variable NBATCH by run-time configurable
+ global variable vegasbatch_.
+
+- Added checks on ncomp.
+
+
+1 Feb 05
+
+- Added a partition viewer which displays the tesselation of the
+ integration region on screen. Needs Qt.
+
+
+27 Jan 05
+
+- Added a preprocessor flag NO_LONG_DOUBLE to disable the use
+ of long doubles on systems that don't have it.
+
+
+25 Jan 05
+
+- Rearranged Vegas to sample in batches of NBATCH points to
+ reduce memory consumption.
+
+
+21 Jan 05
+
+- Fixed bug in Divonne: Final result was wrong if not enough
+ samples left for Phase 3.
+
+
+19 Jan 05
+
+- Updated manual re pseudo-random sampling.
+
+
+17 Jan 05
+
+- Introduced "number" typedef, might be useful when using wide ints.
+ Not well tested, though.
+
+- Substituted [sd]rand48 by Mersenne Twister generator.
+
+
+14 Jan 05
+
+- Added pseudo-rng (bit 3 in flags).
+
+- Collected common declarations in stddecl.h.
+
+- Better checking of dimension (e.g. in Divonne, all cases).
+
+
+12 Jan 05
+
+- Updated manual re vegas{grid,state}.
+
+
+23 Dec 04
+
+- Fixed a memory leak in Cuhre.
+
+
+18 Nov 04
+
+- Added vegasstate load/restore of internal state.
+
+
+16 Jul 04
+
+- Added vegasgrid.
+
