Tracking significant changes to the Twitter API or platform as a whole

twitter-history

Tracking significant changes to the Twitter API or platform as a whole. These largely apply to v1.1 and Premium APIs, not for v2.

Attempting to be accurate to the day for dates, and as exhaustive as possible. The main purpose was to have a reference for when to use certain filters in APIs, and originally created for keeping track of dates when writing about features. Edits / additions welcome.

About

Why?

Archiving mostly, but also as a reference for analysis, for when things can be attributed to platform changes rather than some other changes you may be interested in measuring. It might be useful to consult entries if you have crawls for old tweets, to see what changes / differences you may come across.

What is a significant change?:

Roughly, any change that is platform-wide is included, eg: Major changes to UI like Retweet button. Policy tweaks to TOS, Developer agreement aren't in here, but maybe should be. Suggestions on classifying this better are welcome, I've been arbitrarily deciding what's significant and what's not.

Data:

• date: YYYY-MM-DD

• change: Short label

• type: Rough classification of the type of change

  • UX is any change where users would be impacted somehow
  • ORG is any major organisational change
  • API any change that developers may care about
  • EVT a pivotal event of some sort

• description: A Longer description of the change or impact.

• link: Source URL for this change announcement or documentation.

Todo, Maybe:

• Add column of affected fields and or endpoints, so CSV can be used automatically to check queries for issues (eg: warning that GEO data is unavailable for some date range, etc)
• Bibtex entries for official source and a representative paper.
• Extra column for source of change (docs, blog, other)
• Move Org / Evt "changes" to a separate list, leave only changes with data impact.
