Fastcluster

• Compatibility fix for Solaris.

• Updated citation information (JSS paper).

• Suppress warnings where applicable. Compilation with GCC should
not produce any warning at all, even if all compiler warnings
are enabled. (The switch -pedantic still does not work, but this
is due to the Python headers.)

• Optimization: Hidden symbols. Only the interface functions are
exported to the symbol table with GCC.

• Compatibility fix for the MSVC compilers on Windows.

• Simplified GIL release in the Python interface.

• Test for NaN dissimilarity values: Now the algorithms produce an error
message instead of silently giving false results. The documentation was
updated accordingly. This is the final design as intended: the fastcluster
package handles infinity values correctly but complains about NaNs.

• The Python interface now works with both Python 2 and Python 3.

• Changed the license to BSD.

• Scipy import is now optional (suggested by Forest Gregg)

• Compatibility fix for NumPy 1.7. Thanks to Semihcan Doken for the bug
report.

• Bug fix related to GIL release in the Python wrapper. Thanks to Massimo
Di Stefano for the bug report.

• Small compatibility changes in the Python test scripts (again thanks to
Massimo Di Stefano for the report).
