Release 2018-04-30 - xparse: allow spaces before trailing optional arguments, with new "!" modifier to control behavior - Enable \char_generate:nn for active chars - Deprecated functions expiring at end of 2017 are removed - Old module .sty files largely removed - Add new \tl_analysis_map_inline:nn and rename \tl_show_analysis:(N|n)n as \tl_analysis_show:(N|n)n - Change \int_rand:nn (and rand_item functions) to better use the RNG - Significant internal revision to use only internal functions 'private' to specific modules - Better documentation of cross-module kernel-internal functions - New low-level \int_value:w function - Implement \exp_args_generate:n to define new \exp_args:N... functions - Make prg break functions public - Make scan marks mechanism public - New experimental functions for - Building token lists piecewise - Fast manipulation of integer arrays - Sequence shuffling - \seq_set_from_function:NnN - \char_codepoint_to_bytes:n - Only index TF, T, F functions together if they are expl functions (fixes #453) - Make \prg_do_nothing: long rather than nopar (fixes #455) - Make \infty and \pi into errors in fp expressions (fixes #357) - Several performance improvements - Documentation improvements across l3kernel

l3experimental – Experimental LaTeX3 concepts

The l3experimental packages are a collection of experimental implementations for aspects of the LaTeX3 kernel, dealing with higher-level ideas such as the Designer Interface. Some of them work as stand alone packages, providing new functionality, and can be used on top of LaTeX2ε with no changes to the existing kernel.

The present release includes:

l3benchmark for measuring the time taken by TeX to run certain code;
l3draw, a code-level interface for constructing drawings;
l3graphics, an interfaces for the inclusion of graphics files;
l3opacity, support for opacity in PDF output;
l3str, support for string manipulation;
xcoffins, which allows the alignment of boxes using a series of ‘handle’ positions, supplementing the simple TeX reference point;
xgalley, which controls boxes receiving text for typesetting.
