## Changelog for AERN-Real-0.10.0.1

0.10.0.1: 28 July 2009: fixed a few bugs in meta-data
0.10.0: 28 July 2009
* switching to beta status
* new QuickCheck test suite covering most functionality
* new support for anti-consistent intervals (eg [2,0])
(also called directed or improper; using Kaucher arithmetic)
* new support for inner-rounded interval arithemtic
* fixed errors in some elementary functions for extreme values
* fixed performance bug in arctan
* improved hierarchy of auxiliary modules
0.9.9: 23 February 2009
* Small changes needed in other AERN packages:
* New operation for domain boxes: get its dimension.
* Exponentiation, sine, cosine and arctan signinificantly improved for arguments further away from 0.
* Fixed a bug in sine Taylor series error term.
* Some interval arithmetic operations now have also "inner" versions
that approximate the maximal extension of the operation from inside
(useful for testing the normal "outer" versions).
0.9.8: 1 December 2008
* added instance of the HTML class for intervals
* added syntactic comparison of variable-indexed domain boxes
* some extra miscellaneous functions
* moved miscellaneous facilities for STM from AERN-RnToRm-Plot to here so that they can be used by AERN-Net
0.9.7.2: 7 October 2008
* hmpfr interface now uses a faster toDouble conversion
0.9.7.1: 30 September 2008
* switched the Demo program to a more suitable (ie faster) base
0.9.7: 30 September 2008
* made it easier to switch among various bases (double, mpfr, pure haskell floats...)
* added MPFR backend via hmpfr (cabal install -f "use-hmpfr")
* added two new samples (computing pi, inverting Hilbert matrix) that
demonstrate the speedup when using MPFR
0.9.6.1: 7 August 2008
* revamped package description to make it much shorter and linked it
to the main module
0.9.6: 7 August 2008
* improved domain box class interface and implementation
* fixed broken domain box splitting function
* improved the integer logarithm auxiliary function
0.9.5: 24 July 2008
* new operation for testing disjoing interiors
* real approximations not automatically instances of Ord
because comparison is not decidable in general;
one should use the four-valued compareReals instead of <, =<, ==
* removed rependency on haskell98
0.9.4: 15 July 2008
* fixed buggy formatting of floating point numbers
* added a simple although inefficient linear solver
0.9.3.1: 12 July 2008
* fixed email in cabal maintainer field
0.9.3: 12 July 2008
* Fixed Data.Number.ER.Real so that it is usable as a single import
for the library and its documentation links are more useful.
* Added a module with some tests, which can also serve as an example.
* Improved formatting of floating point numbers.
0.9.2: 11 July 2008
* declared dependency on haskell98 in cabal file (thanks to Don Stewart)
0.9.1: 11 July 2008
* fixed licence specification within modules
0.9.0: 11 July 2008
* initial release of AERN-Real
