First and foremost, the Library map is finished! Everything was reworked from scratch. How the stairs would flow from one floor to the next was actively considered this time around, including how many stairs were visible on each staircase on average. Various "flattened" 3d elements that I missed originally were fixed. Every exterior window was matched to the correct interior window. All in all, this is the probably the definitive version of the Library's layout.
Now if you're wondering why the Library deviation file hasn't been updated... I'm running into a weird DA upload error - "Error uploading file: Unknown error" . Changing the file name, file type, browser, and computer being uploaded from haven't let me bypass the issue. I've been able to update the file for a different deviation, so I'm at a bit of an impasse here. Until I can get the map uploaded, just download it from here:

Now that this map is complete, my original plan was to move on to the other interiors and give them a shine and polish as well. However, after spending so much time working on the Library and figuring out all the fiddly details, I've decided to continue working with the Library and create the detailed 3d model version instead before I start forgetting things. This would include the interior, exterior, all the extra mini details that I couldn't include in the 2d map, the whole nine yards. Once complete, the model would be made available for general purpose use (SFM movies, game prop, Oculus Rift tour, etc.), as per usual. I also intend to submit the finished product to Shapeways (minus the basement) as a 3 piece model that can be opened up in layers to see inside (upper roof, second floor and back room roof, first floor).
Once the 3d model of the Library is complete, I'll move on to the next building. That does mean that the time period between updates to maps will be much more extended than planned. This isn't that big of a deal for most maps (including the main street map) as they are still mostly if not completely accurate. Season 4 didn't really add/change much to the town due to the characters spending so much time outside of Ponyville. The only building that needs a semi-major reanalysis is Carousel Boutique, and that's primarily due to the addition of the bathroom and the spare bedroom on the second floor.
The original plan back in the summer after Season 1 came out was to make a digital 3d model of Ponyville that anyone could explore on their computer that was as accurate as possible. Come every season's end, I spend my spare time updating every single diagram en masse and never any time working on the 3d version. It's time to change my workflow. It'll take longer, but the results will be worth it.
