Twitter is moving to 64-bit Twitter User ID by July 1, 2013, this means that "if you currently use signed 32-bit integers to track user IDs in your system, you should update your code to use 64-bit integers as soon as you can," Twitter stated.
"This includes statically typed variables in your application code and column types in your database code."
Also, Twitter announced a number of updates to "Embedded Tweets" making it to load faster by reducing the number of HTTP requests reuaire to display embedded tweet.
Additionally, it's now even easier to embed a Tweet--"just click the "More" button in any Tweet on twitter.com and TweetDeck, and then select "Embed this Tweet"," the company adds. You can do the same on TweetDeck.
Embedded Tweets now also have full support for Twitter Cards--"letting you embed the fully expanded Tweet within a site."
Finally, the updated design now more closely align with the experience on Tweet permalink pages on Twitter.com, and include live Retweet and Favorite counts.
Twitter Advertising today expands to support advertisers and agencies in the US, UK, Ireland, Japan, Brazil as well as all across the Middle East, North Africa, Southeast Asia and Latin America.
Last year, Twitter announced that it would soon be available in 50 countries.
"Every month, 200 million users worldwide turn to Twitter to connect to their interests. Last summer, the world came together on Twitter and sent over 150 million Tweets during the 2012 Summer Olympics in London. Today, 70% of Twitter accounts are outside the U.S., and Twitter is now available in 33 languages," the company blogged.
