An update has just been pushed out to Google Play Magazines with a small but welcome set of improvements. Version 1.0.1 has home screen and library performance improvements, better recognition of available space for your magazines and bug fixes targeted at the Nexus 7 and Jelly Bean.
These kinds of updates aren't glamorous, but we're okay with that. Every once and a while you've got to get excited about the ones that bring stability to your apps too. If you're a magazine reader, hit the Play Store link above and get your update.
