Changes for version 2.55_3

  • Oct 22 2010
    • The Sturm functions sturm_sign_minus_inf() and sturm_sign_minus_inf() had been documented as exported, but they weren't. They are now.
    • Documentation for the Sturm functions was cut short - either I had accidentally chopped it, or I left off writing it and forgot to get back to it. Took a stab at completing it.
    • Added function sturm_real_root_range_count().
    • Added test file sturm2.t to the t directory, and to the MANIFEST.
  • Oct 19 2010
    • The keyword metadata key isn't an argument to the Module::Build constructor, it's part of the meta_merge hash which *is* an argument to the constructor. Fixed that.
    • Document the varsubst option in poly_option().
    • Made the variable substitution method more efficient by actually removing primes from the list as they're checked. Extended the prime list that gets checked.
  • Oct 18 2010
    • Aaaaaaand of course I forgot to put varsubst.t in the MANIFEST.
    • Updated Module::Build on my system. Maybe get keywords in META.yml now?

Changes for version 2.55_2

  • Oct 18 2010
    • Got the variable substitution code in, and created test file varsubst.t. Undocumented for now.
  • Oct 15 2010
    • More documentation improvments, as I clear away old numeric vs. classical confusion, and add documentation for poly_option().
    • Read the latest Module::Build documentation, and decided to try the keyword item in Build.PL.
  • Oct 12 2010
    • Added division.pl to the eg directory and to the MANIFEST.
    • Was removing leading zeros in poly_nonzero_term_count(), which is pretty pointless. Removed those lines of code.

Changes for version 2.55_1

  • Oct 12 2010
    • And one more document change: I found a call to set_hessenberg(0) where we now want poly_option(hessenberg => 0);
  • Oct 8 2010
    • Added rootf.t to test directory and MANIFEST; it tests poly_roots() with the option "root_function" set.
    • Changes to the poly_option() function for better option handling.
    • Change test files poly0.t and polyfp0.t (which used set_hessenberg($value)) to now use poly_option(hessenberg => $value) instead.
  • Oct 5 2010
    • Documentation change to EXPORT section. Instead of listing exported functions, link to the head3 Functions sections, which are now organized by tag (see Sep 28 2010).
    • Added the poly_option() function.
  • Sep 28 2010
    • Documentation improvement by categorizing the functions by tag and improving the Sturm sequence explanation.
