Based on IBM description of the new version 8.5.3 of Lotus Notes, the following enhancements were delivered in a new version:
- Lotus Notes and Domino 8.5.3 includes entitlement to the IBM Connections files and profiles components adding significant capabilities to help clients become a social business
- Enhanced new mail notification which optionally provides a pop up preview (containing both sender and subject) of new mail messages as they arrive.
- Improved sorting on email subject content that ignores the “Re:” and “Fw:” prefix, from reply & forward respectively, providing a more accurate sorting of your data.
- A new option to search by sender or subject available when you right click an email.
- Optionally leave countered meetings on your calendar. Allow countered meetings to show up in a unique color, with the time the meeting was originally scheduled for as well as maintaining the ability to act on the original calendar invite and with hover text indicating the new proposed time.
- Optionally notify existing invitees when adding or removing attendees from an existing meeting, informing them of the change and updating the invitee list on their calendar invitation, as well as other options which negate the need for a user to process any meeting updates for anything other than a change in time, eg. a reschedule.
- Significant improvements to recent contacts, allowing end users more control over who gets added to recent contacts and improved data integrity.
- Geographic and time zone information is be displayed in the business card.
- Apple Mac usability improvements for e-mail gestures include the ability to drag one or grouped files to the Lotus Notes icon on your dock, and a new mail message will be created with those files attached.
- Embedded IBM Sametime is upgraded to V8.5.1 with an incremental installer to IBM Sametime 8.5.2, and embedded IBM Lotus Symphony is upgraded to V3.0.
- Additional platform support includes RHEL 6.0 Desktop, Citrix XenApp 6.0, and enhanced 64-bit toleration for Microsoft Windows.
