During its lifespan, some updates were devoted mostly for testing new things, like Torches or Fire. Indev received 29 updates after this, gaining a few fundamental features to Minecraft as it went, which are listed below. New features currently contained a more complex and realistic lighting scheme than Classic mode's and support for MD3 mob models, demonstrated by Rana. Indev version 0.31 was put to the public at /indev and available only to people who had purchased the game. Indev was initially released after Notch received requests to let the community try out new features he was implementing. The Indev phase ran from Decemto February 23, 2010, when it was phased out in favor of Infdev, after infinite maps were to be added into the game. No Indev (short for In Development) was the second development phase of Minecraft's Survival mode, which succeeded Survival Test in Classic Mode.
