- Issues
- stats: raise NotImplementedError in conditional_space when normalize=False
- piecewise: fix hang when integrating products of non-overlapping Piecewise functions
- stats: `conditional_space` raises `UnboundLocalError` when `normalize=False`
- Fix conditional_space with normalize false
- Collect function applies order inconsistently
- [GSoC] integrals: expand sqrt_quadratic_rule in manualintegrate
- Fix/refine pow nested 29684
- `(z * conjugate(z)).is_real` gives `None` instead of `True`
- Fix integrate(sqrt(2-x)*sqrt(1/(2-x))) returning -1 instead of 1
- A negative summation is somehow simplified to a piecewise that retains the sum's index even though there are no more summations
