commit 9435d80ac31c97c2a698928e59cc4489f1fad5e7
Author: Richard Kreckel <kreckel at ginac.de>
Date:   Sun Aug 6 19:27:51 2023 +0200

    Fix series of positive powers of polynomials.
    
    Before calling pseries::power_const(), make sure the basis series has
    sufficient terms. In particular, do not shrink the order of expansion
    - only grow it.
    
    Fix various hairy problems in pseries::power_const() when a polynomial
    is raised to a positive integer power.
    
    (The special cases here can actually also be computed by Taylor
    expansion but the fixes should be more general.)
    
    Also add test cases.
    
    Thanks to Vitaly Magerya <vmagerya at gmail.com> for reporting this.

GiNaC -- a C++ library for symbolic computations

Subject: [GiNaC-devel] GiNaC 1.8.7 released
Message-ID: <fcdab8bf-1c31-4a47-ab74-f8f87b2eaf05@in.terlu.de>

Hi,

GiNaC 1.8.7 has been released.

Here're the news:
* Fix series expansion of polynomial(x)^n for small and large n.
   Previously, this could return two Order terms or an Order term
   even though the series was terminating at a lower order.
* Fix bugs in internal parser from strings.
   The operator precedence of the internal parser was inconsistent
   and has now been harmonized with that of ginsh.
* Make ginsh evaluate line-by-line in non-interactive mode.
   This helps programs invoking ginsh as a sub-program.
* Several build fixes.

Happy hacking!
   -richy.
