Recently we attacked some of Grove's core, upgrading many pieces of our stack. Most of it is boring technical things such as moving away from MySQL to PostgreSQL, our personal favorite database.
While that brought us a better stability and performance, the main new noticeable feature is with searching. We've moved to n-gram searching. This doesn't change much for English speakers and other Western Languages, however it does make Grove much more usable for languages such as Chinese and Japanese.
