Time Entry view is now pre-filled with issues updated during the selected day, and work entries are suggested basing on updates performed by current user history. So you just have to submit worklog entry by pressing '+' icon.
Please note, Updated Issues are added, only if there is no complete (Working Hours Per Day) work logged for the day. And in case of Today, Updated Issues are added to Time Entry only if no “In Progress Issues JQL“ is configured.
