Beta version 4 of NSIS 2, the popular win32 installer/uninstaller system, is out. NSIS 2 includes a new Modern UI, supports multiple languages and features an easy plugin system. NSIS is still the smallest win32 installer available, with an overhead of only 34 KB (with default options).
The most noticeable new features are CHM documentation (searchable and has an index), ability to use any page anywhere and any number of times, improved large files handling mechanism, full RTL support, more strings in in the language files (less strings you need to translate yourself), per-file extraction progress, commands to add version resource and user defined variables.
