CTAN update: bnumexpr
Jean-François Burnol submitted an update to the bnumexpr package. Version number: 1.5 2021-05-17 License type: lppl1.3c Summary description: Extends eTeX’s \numexpr...\relax construct to big integers Announcement text: -- - breaking: power operators ^ and ** now right-associative. - bugfixes: two bugs related to hexadecimal input and inherited from usptream xintexpr were fixed. - customizability and extendibility now total: added \bnumdefinfix and \bnumdefpostfix to extend or modify the existing syntax. Already with \bnumsetup (new name of \bnumexprsetup) it was possible, as is now done in the documentation, to let \bnumeval become for example a calculator operating on fractions. With the added \bnumdefinfix and \bnumdefpostfix it is possible to redefine or extend arbitrarily the implemented syntax. For example to add support for numbers in scientific notation via new infix operators `.' and `e' or `E'. Of course, it would then also be needed to map via \bnumsetup the arithmetic operations to suitable macros. -- This package is located at http://mirror.ctan.org/macros/latex/contrib/bnumexpr More information is at https://www.ctan.org/pkg/bnumexpr Thanks for the upload.

CTAN update: siunitx
Joseph Wright submitted an update to the
siunitx
package.
Version: 3.0.0 2021-05-17
License: lppl1.3c
Summary description: A comprehensive (SI) units package
Announcement text:
--
Version 3 is a major update to `siunitx`, which has largely been
re-written internally. A significant number of key-value
settings have new, more descriptive, names. Where possible,
older names are mapped to newer ones internally: you will be
warned in the log if this is the case.
It is possible to use the LaTeX kernel mechanism to load the
last version 2 release for documents that cannot be successfully
processed using version 3. This can be achieved using
```
\usepackage{siunitx}[=2021-04-09]
or
```latex
\usepackage{siunitx}[=v2]
```
In version 3, the document commands have been revised to be more
descriptive. As such, the commands `\SI`,`\SIlist`, `\SIrange`
and `\si` remain available but are not recommended for use in
new use.
Some changes have been made to the semantics of commands or
options. Most notably
- prefixes cannot now be given without units;
- prefixes can only be interconverted with numbers as part of a
quantity, not as stand-alone units.
The font control system has been completely re-written for
version 3. The method used in entirely different from version 2.
Emulation is therefore not provided for some aspects: if you
need non-standard font settings, you will need to adjust your
source.
The input approach for version 3 is slightly more structured and
restricted than for version 2. As well as the updated names for
document commands, this means that
- Products of numbers must now be given using the dedicated
`\numproduct` and `\qtyproduct` commands;
- Quotients of numbers are only supported as literals;
- Complex values need to be given using the dedicated command
`\complexnum`
The letter used for a numerical tabular column can now be
selected by the user: the letter `S` has been retained as the
standard interface. The unit column (`s`) has been removed from
this release. It can be emulated using the `collcell` package,
for example
```latex
\usepackage{collcell}
\newcolumntype{s}{>{\collectcell\unit}c<{\endcollectcell}}
```
or
```latex
\usepackage{collcell}
\newcolumntype{s}{>{\collectcell\si}c<{\endcollectcell}}
```
A new approach has been taken to providing non-Latin symbols for
use in units: these are now handled directly where needed, for
example in the definition of the `\micro` prefix.
If you are using `table-column-width` to have fixed-width
columns, you also now need `table-fixed-width` to set this
option active.
