* [#15839](https://bugzilla.scilab.org/15839): `gsort`: the only sparse possible input were real or complex vectors, and only with the `g` method.
* [#15842](https://bugzilla.scilab.org/15842): `unique` could not process 2D sparse matrices.
* [#16106](https://bugzilla.scilab.org/16106): Xcos sciblk4 user-defined blocks did not handle opar and odstate/oz correctly.
+* [#16274](https://bugzilla.scilab.org/16274): assert_checkequal() did not considered equal matching Nan or void elements in (nested) containers.
* [#16337](https://bugzilla.scilab.org/16337): The 3rd output of `[U,km,ku] = unique(..)` was not implemented.
* [#16342](https://bugzilla.scilab.org/16342): `strcat()` was much slower in Scilab 6.0.2.
* [#16350](https://bugzilla.scilab.org/16350): in if/while conditions, the empty sparse boolean was considered as TRUE.
