We’re proactively making room for more lists on Twitter by expanding their IDs to 64-bit integers. If you’re using our REST and Streaming APIs, you should confirm that your database, server-side and client-side code consume the safe string-based identifiers represented in “id_str” fields instead of the integer-based identifiers found in the “id” field of Twitter List objects and related references.
At the end of 2013, all Browsers and Certificate Authorities will no longer support 1024 bits RSA certificates to be compliant to National Institute of Standards and Technology (NIST) guidelines.
The SSL certificate currently used on api.twitter.com is signed with the older Verisign G2 root CA certificate.
