API Changelog

October 26 2017

Web API

  • Added last reducers ee.Reducer.last() and ee.Reducer.lastNonNull() which select the last element.

October 19 2017

Python API

  • Fixed the Python API's image.rename() method to properly handle a single string.

October 11 2017

Code Editor

  • Added an advanced table upload option to control the precision of geometry transformations performed during upload.
