* [#15269](https://bugzilla.scilab.org/15269): `xgetech` was poor and stiff compared to any combination of `gca()` properties `.axes_bounds`, `.data_bounds`, `.log_flags`, and `.margins`. It is removed.
* [#15271](https://bugzilla.scilab.org/15271): `bitget` needed to be upgraded.
* [#15309](https://bugzilla.scilab.org/15309): `eval` was a weak duplicate of `evstr`. It should be removed.
* [#15321](https://bugzilla.scilab.org/15321): `lu` was leaking memory.

* [#15393](https://bugzilla.scilab.org/15393): In a new figure, `nicholschart` plotted nothing. The default frame color was a flashy cyan. The position of gain labels could be puzzling. It was not possible to specify colors by their names. Postprocessing the frames and the set of labels was not easy.
* [#15421](https://bugzilla.scilab.org/15421): A new smarter default grid_style was required since smart lines styles #7-10 are available.
* [#15425](https://bugzilla.scilab.org/15425): The Kronecker product `a .*. b` failed when `a` or `b` or both are hypermatrices, with one or both being polynomials or rationals.

* [#15628](https://bugzilla.scilab.org/15628): `with_tk` was a duplicate of `with_module('tclsci')`. It is removed.
* [#15643](https://bugzilla.scilab.org/15643): Features with the signed zero -0 were not documented.

* [#15745](https://bugzilla.scilab.org/15745): `diophant(0,0,m)`, `diophant([p 0],q)`, `diophant([0 p],q)` with m<>0 and p>q were wrong. There was no flag for cases with an infinite number of solutions. When there is no solution, some values were returned anyway, instead of []. In this case, the documented definition of the err value was dubious. Decimal numbers and integers were accepted, but not encoded integers. Inf and NaN input coefficients were not rejected.
* [#15812](https://bugzilla.scilab.org/15812): While assigning variables the source variable may become corrupted.
* [#15821](https://bugzilla.scilab.org/15821): `fac3d` and `fac3d1` were still in Scilab 6.0 despite they were tagged obsolete 14 years ago in Scilab 4.1

* [#15977](https://bugzilla.scilab.org/15977): The documentation for `wavread(..,'info')` had a mistake. The `wavread` page deserved some improvements.
* [#15978](https://bugzilla.scilab.org/15978): The `writewav` page in English said that input data are one column per channel, instead of one row per channel. In addition, in case of writing error, `savewave` kept the output file open and locked.
* [#15979](https://bugzilla.scilab.org/15979): `EXPRESSION`, `CLR` and `DLR` Xcos blocks did not (always) correctly display multicharacter exponents in expressions displayed in their icons.
* [#15981](https://bugzilla.scilab.org/15981): `wavread` kept the wav file open and locked when returning on errors. It weakly managed the input file name. It claimed for invalid data formats instead of unsupported ones, with poor information about the current format vs the supported ones. Several error messages referred to a wrong function.
* [#15983](https://bugzilla.scilab.org/15983): `group` regressed in 5.5.2 due to a too intrusive fix.

* [#16062](https://bugzilla.scilab.org/16062): `tbx_make` did not allow easily to force building all toolbox sections without the toolbox builder (if any). `tbx_make(Dir,"*")` now does it.
* [#16064](https://bugzilla.scilab.org/16064): `tbx_make(Dir,'localization')` did not update `.mo` files from `.po`.
* [#16065](https://bugzilla.scilab.org/16065): Building help pages including some <scilab:image> tags used and finally deleted the current on-screen figures (if any)!

* [#16104](https://bugzilla.scilab.org/16104): `assert_checkequal` did not support properly or at all Nan and void in lists, Nan in sparse, implicit lists, macros, libraries, built-in functions, graphical handles. For input arrays or lists of matching typeof and sizes, the failure message displayed neither the index nor the values of the first mismatching elements.
* [#16108](https://bugzilla.scilab.org/16108): For the CSCOPE and CMSCOPE blocks, the Label&id parameter entered in their interface were not displayed below the block's icon.
