UPDATE (10/25/12):  Last night we pushed v2.9.7 to Google Play which resolves the issues from v2.9.5 and 2.9.6.  Knots 3D is now again available on Google Play for download and update.


Last night we pushed out the v2.9.5 update to Google Play which had a bug fix and a minor UI change. Unfortunately, users who upgraded had package signing errors and were unable to update. It turns out that the process used to remove the un-needed permissions and libraries is no longer working and resulted in an invalid apk file. See extensive post and discussion regarding the CoronaSDK bundled permissions here and here.

The Google Play developer console does not allow developers to revert back to a previous version so the only way to fix the above was to release a new version of Knots 3D, v2.9.6, without removing the Corona Bundled permissions. This was released several hours after v2.9.5 last night. After receiving emails and negative reviews regarding the permissions, I have decided to pull Knots 3D completely from Google Play. I understand the concerns over privacy and do not want to alienate those users for which this is an issue. Hopefully we can again figure out how to get the apk package properly built without the default Corona permissions and return Knots 3D to the Google Play store.

Our apologies for the inconvenience and confusion.

BUG FIX SUBMITTED, PENDING APPLE REVIEW: v2.9.1 of Knots 3D was released to the iTunes store 10/9/12 with updates for iOS6 and the new 4″ display on the iPhone 5. Unfortunately it introduced a minor bug on older devices with smaller screens where the last row of the knot list is not reachable or displayed, e.g. Zeppelin Bend. This bug has been fixed and submitted to Apple. We expect it to be approved and available on or around 10/18. Thanks for your patience and understanding.

After the iPad 3 became available late last week several users informed me of a bug on the iPad 3 making Knots 3D unusable.  We worked on a fix over the weekend and have submitted it to Apple for review and approval.  It typically takes Apple about a week to approve new releases and updates so hopefully the latest version of Knots 3D including the Retina Display bug fix for iPad 3 should be available around March 26. I have asked Apple to expedite the fix so it may possibly be available before that.  The good news is the release also includes over a dozen new knots along with the fix including: Alpine Butterfly, Truckers Hitch, Palomar Knot, and more.

Thanks for your patience and understanding.
