This file records noteworthy changes.
-1.0.9 (<date>)
+1.0.15 (11 August 2003)
+* Added on-line help and Tab-completion for print(), iprint(), print_latex()
+ and print_csrc() in ginsh.
+* Fixed a bug in the unarchiving of sums and products: terms were not
+ reordered in a canonical way.
+* Fixed a bug in normal()/numer_denom(): denominator was not made unit
+ normal if it was a simple number.
+
+1.0.14 (1 March 2003)
+* Improved the C-source output: complex numbers are printed correctly (using
+ the STL complex<> template or cln::complex()), rational numbers use cl_RA()
+ in the CLN output, and small integers are printed in a more compact format
+ (e.g. "2.0" instead of "2.0000000e+00").
+* function_options::set_return_type() and function_options::do_not_evalf_params()
+ now actually work.
+
+1.0.13 (27 January 2003)
+* Contracting epsilon tensors with Euclidean indices now works.
+* Improved dummy index symmetrization in sums.
+* Added dirac_gammaL/R(), which can be used instead of dirac_gamma6/7()
+ but are single objects, to allow for a more compact notation of Dirac
+ strings.
+* Powers with negative numeric exponents are printed as fractions in the
+ LaTeX output.
+* Added symbolic_matrix() for the convenient creation of matrices filled
+ with symbols.
+* Added collect_common_factors() which collects common factors from the
+ terms of sums.
+* simplify_indexed() converts "gamma~mu*p.mu" to "p\".
+
+1.0.12 (30 October 2002)
+* Fixed a bug in power::expand() that could produce invalid expressions.
+* The input parser no longer ignores extra data following accepted input.
+* Improved the CLN C-source output (integers are printed as integers, and
+ floating point numbers include the precision).
+* Fixed a problem in the LaTeX-output of negative fractions.
+* Added print_latex() and print_csrc() to ginsh.
+* The sprem() function is now public.
+
+1.0.11 (18 September 2002)
+* Fixed a possible memory corruption in contractions of indexed objects with
+ delta or metric tensors.
+* Computing the derivative of a power series object with respect to a symbol
+ that is not the expansion variable now works correctly.
+* Several bugfixes in code generation.
+
+1.0.10 (24 July 2002)
+* Powers of indexed objects are now parenthesized correctly in LaTeX output.
+* Input parser handles indices (they have to be specified in the same list
+ as the symbols).
+* Added some limited support for subspaces in the idx and tensor classes.
+* Fixed a bug in canonicalize() (antisymmetric canonicalization of an already
+ sorted list containing two or more equal objects failed to return 0).
+
+1.0.9 (11 June 2002)
* simplify_indexed() now raises/lowers dummy indices to canonicalize the index
variance. This allows some simplifications that weren't possible before,
- like eps~a.b~c~d*X.a*X~b -> 0.
+ like eps~a.b~c~d*X.a*X~b -> 0 and X.a~a-X~a.a -> 0.
+* Implemented relational::subs().
+* Fixed bug in simplify_ncmul() for clifford objects.
1.0.8 (31 March 2002)
* Improvements in memory usage of the expand() methods.
