There are not many changes in 1.13.2 (see below).

• core

  • An inconsistency in Float/Rational comparisons was fixed. SymPy 1.13 made it so that Rational(n) != Float(n) but this was inconsistent in the case of Rational(0) == Float(0) and Float(0) == Rational(0) which gave different results. Now both give False. (#26948 by @oscarbenjamin)

• functions

  • Fixed a bug that caused LambertW to hang on specific inputs. (#26841 by @haru-44)

• integrals

  • A regression introduced in SymPy 1.13 in the heurisch integration routine was fixed. The regression prevented some integrals from being evaluated. (#26940 by @oscarbenjamin, @smichr, and @sylee957)
