1. Refinements to the subscription logic. In case you run into any issues please do not hesitate to contact me

1. 'Stack Trainer' is moved to a subscription model supporting a 3 months subscription and an annual subscription. Existing users will continue as purchased users and will not notice the change. A big thank you to all early adopters who enabled this important milestone towards a sustainable future for 'Stack Trainer'! 2. Code maintenance

1. A new mode named 'Each Position' is added. 'Each Position' starts off from the stack in random order challenging you to identify each position's card. Depending on the active filter either exactly 52 cards, or just the 12 court cards, the 26 black or impair cards, etc., are dealt with no repeats until the final card is reached. The time for each cycle is reported and copied to clipboard in [min:sec] time format. 2. The 'Next Card' mode was modified and is made subject to the active filter. If, for example, the filter is set to 'Impair' then any next card shown will be on an impair stack position. This modification allows to parse each 2nd card in a stack back and forth.

The single tap gesture, used to initialize new cycles, is now replaced by the more pronounced double tap gesture. It is also moved to the lower section of the screen to avoid potential conflicts with the swipe action on the upper screen.

1. The new Stack Filter menu allows to filter the stack to meet a set of criteria. Filters can be set for - ranges 1-13, 14-26, 27-39, 40-52, - a custom range set through a dialogue box - pair and impair positions - red and black cards - any of the four suits - court and number cards

1. The link to the Settings panel is restored. 2. The links to external URLs for the Appstore and the yeahgic website are restored. 3. The new menu item Context Help provides dedicated introductions and descriptions for each of the nine modes. In earlier versions the mode instructions were given under the generic help menu item. The new Context Help make it easier to access and study the details.

1. User defined peg words for cards and numbers, named "House Peg Cards" and "House Peg Numbers", can now be provided through the Settings panel. 2. The "Show Stack" option now also includes the sequences for the peg words. Included is also a check on the element count. 3. A complete set of the three files required for user defined stacks and peg words, i.e. myStack1.txt, myPegCards1.txt, and myPegNumbers1.txt, is automatically provided in the app's document folder. These files serve as templates to make providing customized peg sets easy. 4. The app's document folder, named gicStack, is now accessible through the File app (which is available on latest iOS environments). 5. Code maintenance

1. Additional approaches were added to support the processing of full or partial stacks aiming towards an even more comprehensive stack agility. - Wrong Card: Identify the one card that is displaced - Missing Card: Find the missing card - Spot: Spot a specific card - Highest Card: Identify the high and low cards of a random sub-stack. These new features are experimental and will receive further maintenance in upcoming releases. 2. The Settings panel now allows users to specify a custom stack sequence in text format. This sequence, addressed as the "House Stack" can then be selected as the Stack. The previous option to provide custom stacks through text files remains. 3. The new "Show Stack" menu item reports the active stack sequence in text format ready to be copied to memory. 4. The new "Context Help" menu provides on-spot guidance for each of the eight approaches. 5. Code maintenance

1. Two new approaches: 'Get Card' and 'Get Position'. These two approaches allow to query cards at random positions, and vice versa. 2. The new approaches are also supported on the interactive stack viewer to deliberately query cards and positions in context of the entire stack. 3. A new toolbar 'back' button, which enables to toggle the approach backwards. This complements the already existing 'forward' button. 4. These enhancements make v3.0 a major release. 5.

1. When in 'Four of a Kind' or 'Next Suits' mode, now, the interactive Stack Analyzer indicates the distance between the consecutive cards of the same type (the same kind, the same suit), in both directions. This new detail adds towards further agility in handing the stack. 2. Code maintenance

- Peg words and numbers have been integrated and will be displayed in the interactive stack viewer. - Peg words help to memorize a given stack, they also bring freedom and choice to experiment with new stacks. This new feature ensures you keep remembering your peg system, even if you don't need it anymore for a fully memorized stack. - By default Harry Lorayne's Peg System is applied as described in his books 'Ageless Memory' and 'The Memory Book'. In addition, user defined peg words for the 52 cards and 52 positions can be assigned similar to the way user defined stacks are handled.

1. Adjustments for iOS 8

1. High precision playing card images by courtesy of Vectorized Playing Cards 1.3 (http://code.google.com/p/vectorized-playing-cards) have been integrated. This optional new feature allows for realistic mind-input when training stacks. The card images are supported by the "Next Card" modus.
