3. Upload API

The recommended way to upload apps is to use the upload API. In order to add release notes, use the comment field.

Example:

curl https://upload.testfairy.com/api/upload \
    -F api_key='your_api_key' \
    -F file=@sample.apk \
    -F symbols_file=@sample_mapping.txt \
    -F testers_groups='friends,beta' \
    -F notify='on'\
  -F comment='Put Release Notes Here'

4. Jenkins

By default, The TestFairy Jenkins plugin will use the comments that were included in every commit, in a pretty standard way.
In order to add your own release notes, create a text file in the following location:

$JENKINS_HOME/jobs/$JOB_NAME/builds/$BUILD_ID/testfairy_change_log

The content of this file will override the default changelog.
