Breaking Changes

Check Command

Introduced a new approach to processing grammar and spell check requests. We switched to per-sentence proofreading rather than meaningless per-word check. Now in a single request in such products as WProofreader and SCAYT plugin for CKEditor 4, we send up to 10 tokens (sentences) using a new unified command check for checking text for spelling and grammar problems at the same time.

If you are using Web API, you can consider migrating to a new check command rather than using spelling and grammar checking commands separately. Check this Check Command guide which outlines the list of all available parameters and possible values, structure of request and its response. Along with that we added Overview of HTTP Response Status Codes that you can find helpful in case of errors.

Usage Limits for Cloud Services

The new approach resulted in almost 20-fold increase in the amount of text processed in comparison with the old approach. More information about this change is available in our blog post Major Cloud Services Upgrade: 20x and 10x Bigger Package Sizes For Our Paid and Free Users.
