Changes to “all-following” behavior in Google Calendar

In December 2013, Google Calendar introduced a new behavior for "all-following" changes to recurring events, allowing users to modify the entire series of events without splitting them into separate series as was previously done. This update enables users to perform operations such as modifying, replying, deleting, or applying additional "all-following" changes to recurring events while preserving specific changes to individual instances within the series. To maintain backward compatibility, API clients will still display a separate recurring event after each "all-following" change, and further API support will be announced to enhance these functionalities. An example illustrates how a user can make multiple changes to a recurring event, such as adding a new attendee or changing the location, while still preserving individual responses from other attendees. The changes ensure that all attendees see the series as a single entity, allowing them to manage it collectively with ease. The post concludes with a light-hearted note about Grisha Yakushev's interests and a nod to the consistency and safety of users' data on Calendar servers.
