#OpenRefine version 3.6 is getting closer.
This new version comes with pretty exciting new GREL functions, like detectLanguage() to guess a text's language, replaceEach() to replace several substrings at once, and XML/HTML/URI parsers. Also some simple usability improvements, like downloading the JSON history instead of copy-pasting.
Feel free to download and test to make the release better: https://github.com/OpenRefine/OpenRefine/releases/tag/3.6-beta2
