4.1.0

• Added the ability to specify the knot vectors in the object-oriented interface.
• Various minor updates to formatting and documentation.

4.0.0

• Made thread safe by adding non-optional inbv and ilo inout arguments to the db*val routines. Note that this breaks backward compatibility (to update to the new version, add these arguments, and initialize the variables to 1 on before the first call). The interface for the object-oriented version is unchanged.
• In the object-oriented interface, fixed an issue where the class argument was intent(in) rather than intent(inout).
• New, more comprehensive error return codes (iflag values) and message printing.
• Minor change to avoid creation of an array temporary on the Intel compiler.
• Various other minor updates and addition of a new unit test.

3.4.1

Minor typo correction in an error message.

3.4.0

Added new error codes, and printing of all error messages to the error_unit.

3.3.1

• Minor updates to the documentation.
• Minor change: added private to the abstract bspline_class.

3.3.0

Added 1D routines with matching interfaces for the subroutine and object-oriented modules.

3.2.0

• The object oriented interface now keeps track of the initialization parameters (iloy, etc.) for efficient processing in each dimension.
• Some updates to the documentation for the latest version of FORD.

3.1.0

• The bspline types now have a base class.

3.0.1

Fixed a bug in the 4d object-oriented initialize routine.

3.0.0
