Changes from version 7.0 to 8.0:
================================
Changes of syntax and output:
* Hexadecimal constants ending on '+' or '-' (e.g., 0x123p-) now
provoke a syntax error (as it always should have).
* The match construct on error now matches (it used to return
error).
* In certain cases, procedures could not be applied to an empty set
of arguments because a syntax error occurred before. This is now
possible.
* The meaning and use of infinities and signed zeros in intervals
has been changed (see documentation for details).
* Input and output of decimal constants is now fully exact in
rationalmode. In all other instances, a warning message is now
produced when an internal constant gets printed in decimal and a
rounding occurs.
Critical bug fixes:
* Making Sollya compile again with recent versions of fplll (at
least on the Linux side).
Improvements in internal handling:
* Improved performance on manipulation of polynomials.
Major bug fixes:
* Patched a bug in interval erfc.
* Patched a bug preventing match to work on unary minus.
Major new functionalities:
* The interpolate command allows for polynomial interpolation with
and without error (see documentation for details).
* The bezout command allows for computation of a gcd along with
matching cofactors (see documentation for details).
Minor new functionalities:
* The externaldata command now allows generic external library
symbols to be bound to Sollya objects (see documentation for
details).
* Improvements on use of the L'Hopital rule for function
evaluations.
* When started as an interactive tool or as a library, Sollya now
binds the executable's 0th argument to the Sollya identifier
__program_name.
* In situations when the user wishes to provide the minimax with
real coefficients to fpminimax, it is now possible to give a list
of coefficients instead of the expression of the real minimax (see
documentation for details).
* The free mathematical variable can now be unbound with the rename
command (see documentation for details).
* The bind command now allows for procedures with an arbitrary
number of arguments (see documentation for details).
* The char *sollya_lib_get_help_text(char *topic) function now
allows for access to the help text of a certain topic.
Others:
* In certain circumstances, the printing of a list may have had
quadratic complexity in the past. This has been corrected.
* If the compiler supports the -flto flag; this option is disabled
by default though. To enable LTO compilation, use
--enable-lto-compilation. On certain systems the -flto flag is
supported by the compiler but LTO compilation fails. In this case,
it is recommended not to enable LTO compilation.
* dirtyfindzeros used to include in the list of zeros any point
where the expression given as input evaluated to NaN. Such points
are now included only when there is a real suspicion that it could
be a true zero of the expression.
* externalprocedure, externalfunction and externaldata entries can
have cross-dependencies for their symbols. The tool now makes sure
all symbols are unloaded in the precise inverse order of their
loading, to allow for such cross-dependencies.
* chebyshevform command can now be used out of execute() statements.
* remez command now tries to recognize the situation when the
optimal error function is identically 0.
* configure now allows for cross-compilation.
Deprecated functionalities:
* Deprecated readxml and printxml.
* Deprecated the proof generation feature of the infnorm command.
* Deprecated end-elliptic lists ending with a number as a format
list in fpminimax.
And many bugs fixed.
