Version 1.7.5 of Minecraft was released on February 26. The JDRGaming Minecraft page will be updated later today, and the JDRGaming Minecraft server soon after that.
The new version was announced on the main Mojang blog (https://mojang.com/). Unfortunately, the Mojang blog is also used for updates to other games, so there's a lot of noise there. It remains to be seen whether the Minecraft developers will be diligent in posting update information to the Mojang blog.
