the upload daemon got this one to me while i was processing the previous one:

> The following information was provided by the package's contributor.
> Name of contribution: expl3
> Author's name: LaTeX3 Project
> Location on CTAN: /macros/latex/contrib/expl3/
> Summary description: Packages supporting LaTeX3 programming conventions
> License type: lppl
> Announcement text given by the package's contributor:
> ----------------------------------------------------------------------
> ----------------------------------------------------------------
> ----------------------------------------------------------------
> The expl3 bundle: Low-level LaTeX3 programming conventions
> ----------------------------------------------------------------
> The files of the expl3 bundle provide a low-level API for TeX
> programmers with special syntax conventions, completely 
> separating it from document level syntax. Hence, the commands 
> provided are not intended for use at the document level nor for
> use in describing design layouts in document class files.
> This API provides the foundation on which the LaTeX3 kernel 
> and other advanced extensions are built. Special care has been
> taken so that they can be used within a LaTeX2e context as 
> regular packages.
> The TeX and eTeX primitives are all given a new name according
> to these conventions. However, in the main direct use of the 
> primitives is not required or encouraged: the expl3 modules
> define an independent low-level LaTeX3 programming language.
> At present, the expl3 modules are designed to be loaded on top 
> of LaTeX2e:
>   \usepackage{expl3}
> In time, a LaTeX3 format will be produced based on this code.
> This allows the code to be used in LaTeX2e packages now while a
> stand-alone LaTeX3 is developed.
> ----------------------------------------------------------------
> This release (SVN 1981)
> ----------------------------------------------------------------
> The first stage of creating a fixed-point arithmetic system for
> LaTeX3 is included in this release. The new module (l3fp) is
> loaded as part of expl3, and currently offers basic arithmetic
> only (addition, subtraction, multiplication and division).
> Trigonometric and logarithmic functions will be added to this
> module in the coming weeks, as will the necessary machinery to
> use Lua for mathematics, when available.
> This release also increases the coverage of the category code
> stack implemented by \ExplSyntaxOn/\ExplSyntaxOff, with the
> intention that 'problem' category codes will not cause issues
> within code blocks.

thanks for the upload; i've installed the new version and updated the
catalogue repository.

> Users may view the package catalogue entry at

and the web catalogue entry will change in two characters, overnight
(apart from the date of creation, of course...).
