What does a tool maker do when his tool breaks? He builds a new tool to patch the broken one. At least that is what David Beckemeyer (Mr Blog) did when his tweeting garage door opener was threatened by the approaching OAuthpocalypse. This date with destiny for all Twitter programmers is the planned June 30th cutoff of basic authentication. At that point all Twitter apps must communicate with the API through OAuth authentication instead of the much less complicated user name/password form of HTTP Authentication. There are many good reasons for this change, which have been repeated endlessly on the Twitter developer forum, but in practice it is a lot of added complexity, more complexity than David wanted to build into his little, simple garage door device.
Facebook has announced that it will soon upgrade Graph API v2.3 users to v2.4. The automatic upgrade will take place on July 10th as part of Facebook's 2 year deprecation cycle. Significant changes from v2.3 to v2.4 require pre-migration attention from developers to avoid app disruption.
