The timeline on a Zoho CRM record now shows history going back up to 3 years, a substantial increase on the shorter windows it used to be limited to.
A longer timeline window is particularly useful for tracking activity across longer sales cycles, getting a fuller picture of a record's history at a glance, supporting compliance requirements, and making audits easier, since you're no longer limited to a narrow recent slice of a record's activity.
Alongside the extended date range, the timeline also picked up the ability to add notes directly against timeline events, filter which events are shown, and see email status directly from the timeline itself. See our articles on the New Enhanced Timeline and the New Timeline Interactions Tab for more detail on these.
