New Features:
- Many new types of L-functions have been added, together with
utility functions for working with them. The most prominent new
L-functions are for Hecke characters, and Hecke Grössencharacters.
These are important in the development of Tate's thesis.
- The machinery for tensor products has been improved, so that
they can be computed in more situations of arithmetic interest.
- Complementary to tensor products are symmetric powers, which have
been implemented in the simplest cases (for degree 1 L-functions),
and for elliptic curves over the rationals. Although general machinery
exists for symmetric powers, it is not yet very robust.
- Utility functions that provide access to information associated with
an L-functions, such as EulerFactor, have been added.
- Internally, some of the computations with products of L-functions
have also been changed.
Bug fixes:
- A problem with TensorProduct with LSeries has been fixed.
The ``weight'' of the tensor product should now be correct
for GL(2) (for instance, when tensoring two elliptic curves,
or more generally two modular forms).
