Gmail used to have a limit of 10,000 contacts. For most of us, this was way more than enough, but we heard from some of you who use Gmail to communicate with more than 10,000 people. We want you to be able to store all of your contacts in a single place, so starting today, we’ve increased the limit for all Gmail users, including all those of you who use Google Apps, to 25,000 contacts.

Also, previously an individual contact could be no larger than 32KB — big enough for most people, but not always sufficient for those who like to keep a lot of notes on individual contacts. Now, each contact may be up to 128KB in size, allowing you to store more information in the notes field.
