Hell all, I have just submitted an update to CTAN. Key changes: - New definition for experimental \char_(g)set_active_eq:NN - Revamp \tl_rescan functions to better handle spaces and newlines - New \exp:w for low-level expansion - Provide control of how round rounds ties in \fp_eval:n - Provide expandable errors for programmer - Documentation tweaks - Improvements in ..._show function formatting - Internal tightening up of function naming Also for l3build - Normalise out loading of .fd files - Correctly handle engine == "etex" and format == "latex" with modern TeX systems - Improvements in handling of 'packed' tests (thanks to Dominik Fischer) Please allow 48 h for this to propagate around CTAN.
