I'm sure it's hard to maintain the guide with all the dragons (and new ones coming out about once a month now), so here's what I've noticed:
Pumpkin/Harvest dragons can't breed, and the Vampires have the bite function now. The Bright Pinks no longer breed other BP's, just reg pinks now. As for Zombies, they were again available this year, and one just had to kill a dragon and attempt to revive it. No hatchling sickness required.
For Stripes, I know that some of that information is wrong, but I don't have a great link to trusted information at the moment. Hopefully someone else can submit something. However, I know that Pinks (Bright or not) do not yield Red Stripes.
Also, every time you cite a specific time, you give the time zone as EST. This is Eastern Standard Time, and it's not always true. When the East Coast of the USA is on DST, the time zone is then EDT, and this does affect things if people are using an online calculator to figure out the difference in time zones—an hour may be lost in translation as not everyone observes DST (and not at the same time, so they wouldn't know when to use which one). EST is UTC-5 while EDT is UTC-4. Perhaps the best way to shorten it is ET or NAEST. Official time is: http://time.gov/timezone.cgi?Eastern/d/-5/java
