Bluescarni Piranha Versions Save

An emergency bug-fix release to deal with a compilation error with GCC 8.1, seemingly caused by a compiler bug. This release is based on 0.10 and it does not contain any of the new code being worked on in the master branch.

Release of version 0.10.

Release of version 0.8.

This release is an incremental release over 0.7. It includes no new features and a few bugfixes, involving mostly the Windows and OSX platforms. @isuruf did a great job with the implementation of the OSX CI support and including piranha/pyranha in conda-forge.

This release also reduces the dependency on compiled Boost libraries, by switching to the header-only variant of the unit-test library and dropping the dependency on the Boost timers.

Release of version 0.7.

This new version concerns mostly pyranha. In addition to important bugfixes for Windows, two breaking changes are introduced:

• the square brackets [] are now used in the type generator template syntax,
• the type short has been replaced by int16.

In particular, the first bit means that code such as

>>> from pyranha.types import polynomial, rational, monomial, int16
>>> pt = polynomial(rational,monomial(int16))()

needs to be rewritten as

>>> from pyranha.types import polynomial, rational, monomial, int16
>>> pt = polynomial[rational,monomial[int16]]()

The intent is to have a better visual distinction between type generators and type generator templates, and in some sense to mimic more closely the corresponding C++ syntax (i.e., polynomial<rational,monomial<std::int16_t>>).

This release introduces a new serialization API which is incompatible with earlier versions of piranha.

Data saved with earlier piranha versions can be ported to the new API as follows:

• check out the s11n_legacy branch: https://github.com/bluescarni/piranha/tree/s11n_legacy
• configure and install piranha with msgpack support
• load the old data with the old API, save it with the new API using the msgpack format. E.g., from python:

pt = polynomial(rational,monomial(rational))()
foo = pt.load('myfile.bz2',pyranha.file_compression.bzip2)
pyranha.save_file(foo,'newfile.mpackp.bz2')

This will save the foo polynomial, loaded via the old API, to the file newfile.mpackp.bz2 using the compressed msgpack portable format.

This release fixes compilation with AppleClang on certain setups.

A small bugfix release. Most notably, trying to build from a source tarball (rather than from a git checkout) should now work :)

This release contains a critical fix for upcoming GMP versions.

This is the initial alpha release of the Piranha computer algebra system.
