    v169 v170  
    4444   * #21939 - Solving with respect to a dummy variable behaves wrong
    4545   * #21946 - solve(x==x, x) returns [x == r1]
    46    * #24800 - bug with a system involving square roots, apparently do to an interface issue, Sage not being able to parse conditional answer provided by Maxima
    4746   * #24939 - solve should not convert floating point to rationals when solving
    4847 * Enhancements
     
    7776   * #24117 - `integrate(sqrt(1-4*sin(x)^2),x)` is wrong
    7877   * #24316 - sqrt(sin,cos...)
     78   * #25636 - ECL crash: x^m/sqrt(a + b*x^(2 - m))
    7979   * `abs_integrate`-related errors (see #12731 for possibly disabling or raising warning always with it)
    8080     * #13097 - integral of ln(1+4/5*sin(x))
     
    245245 * #24255 - Warn with substitution of derived classes using equality
    246246 * #24283 - Implement Expression.has_function(...)
    247  * #24425 - Fix inherently failing random_expr doctest
    248247 * #24428 - Substitution should be the same as numerical evaluation
    249248
     
    259258 * #20784 - not all symbolic equations stay unevaluated
    260259 * #21070 - comparison with wildcard raises error
    261  * #21201 - Add a global is_trivial_zero function
    262260 * #21862 - Symbolic methods work inconsistently on relational expressions
    263  * #24440 - Infinite loop from proving an expression
    264261 * #24658 - Don't call Maxima with no-variable symbolic relation tests
    265262 * #24726 - Sage silently accepts symbolic expressions with two comparison operators
     
    283280
    284281== specific Pynac/GiNaC issues ==
    285  * #6344  - Typesetting partial derivatives in new symbolics
    286282 * #6756  - Implement `diff` format symbolic derivative in new symbolics
    287283 * #10069 - Typesetting with hold=True can be weird

    365364 * #24773 - Delayed/Conditional Substitution
    366365 * #5574  - taking symbolic powers should coerce objects to symbolic expressions
