Google's John Mueller announced in a Google+ post that there have been a handful of updates to the Search Console API (formerly the Webmaster Tools API). This is the API that lets you add sites to a Search Console account, retrieve data and diagnostics, and submit sitemaps.
One update is the addition of pagination in Search Analytics. You can request over 5000 rows of data for your site without having to iterate through filters, he says.
Additionally, crawl errors now include "linked from" info from the start. See urlCrawlErrorsSamples.list here.
Finally, the API has higher and clearer quotas.
Mueller says he'd like to see what you make with the API, and encourages sharing in the comments of his post.
