The link in the previous update for downloading from my website sin't working for some people.
Please use the link in this update instead.
The Babbington Press continues its step-by-step, layer-by-layer, version-by-version publication of Persistence with Version 2.0.
Version 2.0 is free, but you will need an iPad or Macintosh to read it.
Version 2.0 is now in the iBooks Store and is also directly downloadable from my website.
To download it from the iBooks Store, follow this link: https://itunes.apple.com/us/book/persistence/id946754502
To download it directly from my website, click this link: http://www.erickraft.com/persistence
You will find the download link on that page.
If you download from my website, a zipped file of Persistence 2.0 should start downloading immediately. When the downloading is complete, you should find the file “Persistence Version 2.0” in whatever folder your downloads download to. On my Mac the file unzips automatically. However, you may get a zipped file. If so, double-clicking it should open your unzipping app and unzip it.
