Hi David,
If you go at the following link:
http://www.dynagram.com/Scripts/Upda...?L=1&P=M&PR=IN,
you will find all the new features since version 2.5.
Version 6.5 is the same as 6.1 except for the compatibility with OSX Tiger and Quark 6.5 so no description is available (Only for this version). Scroll the page downward and you will find the descriptions for each upgrades.
Both versions Dynagram released, version 5 and 6 work very well with PDF's but the company also offers a standalone application called Dynastrip. You can switch to Dynastrip at a lower cost if you are a current 2.5 user. The deal is that you get a free upgrade on the 30x30 inch version (2495$us). If you need the unlimited size version of Dynastrip, you get 1000$ off + a free upgrade to INposition 6 (3495$ instead of 4495$).
If you need a PDF solution, I definitely suggest you look at Dynastrip (*there is a downloadable demo version available on their website...
www.dynagram.com) but INposition 5 or 6 will also do the job. what is good about Dyna is that you can mix different jobs on one plate so commercial work like flyers, business cards, postcards can all be imposed on one same sheet.
Hope i am not pushing Dynastrip too much!!! but it is worthwile taking a look at it.
