v2.1.0 Release

We are pleased to present 2.1.0! This release adds some significant new features including:

• Multi-wiggle tracks - This allows, for example, multiple bigwig files to be displayed in a single track with synchronized scalebar settings. See multi-wiggle docs for more info.
• Undo and redo functionality, let's you undo an operation in the UI e.g. closing a view, closing a track can be recovered
• An alert when the dotplot view renders features that go beyond the bounds of the selected region. This is often an indication that the wrong assembly is being used or the query and target are backwards

Example links for multi-bigwig sessions
