+## New Features
+
+
+
+###
+ - <!-- JAL-1847 JAL-2944 --> New Structure Chooser control for disabling automatic superposition of multiple structures and open structures in existing views
+ - <!-- JAL-984 --> Mouse cursor changes to indicate Sequence ID and annotation area margins can be click-dragged to adjust them.
+ - <!-- JAL-2885 --> Jalview uses HTTPS for Uniprot, Xfam and Ensembl services
+ - <!-- JAL-2759 --> Improved performance for large alignments and lots of hidden columns
+ - <!-- JAL-2593 --> Improved performance when rendering lots of features (particularly when transparency is disabled)
+ - <!-- JAL-2296,JAL-2295 --> Experimental features in 2.10.2 for exchange of Jalview features and Chimera attributes made generally available
+
+
+## Issues Resolved
+
+
+ - <!-- JAL-2899 --> Structure and Overview aren't updated when Colour By Annotation threshold slider is adjusted
+ - <!-- JAL-2778 --> Slow redraw when Overview panel shown overlapping alignment panel
+ - <!-- JAL-2929 --> Overview doesn't show end of unpadded sequence as gaps
+ - <!-- JAL-2789, JAL-2893 --> Cross-reference handling improved: CDS not handled correctly if transcript has no UTR
+ - <!-- JAL-2321 --> Secondary structure and temperature factor annotation not added to sequence when local PDB file associated with it by drag'n'drop or structure chooser
+ - <!-- JAL-2984 --> Answering 'No' to PDB Autoassociate dialog doesn't import PDB files dropped on an alignment
+ - <!-- JAL-2666 --> Linked scrolling via protein horizontal scroll bar doesn't work for some CDS/Protein views
+ - <!-- JAL-2930 --> Trackpad scrolling is broken on OSX on Java 1.8u153 onwards and Java 1.9u4+.
+ - <!-- JAL-2924 --> Tooltip shouldn't be displayed for empty columns in annotation row
+ - <!-- JAL-2913 --> Preferences panel's ID Width control is not honored in batch mode
+ - <!-- JAL-2945 --> Linked sequence highlighting doesn't work for structures added to existing Jmol view
+ - <!-- JAL-2223 --> 'View Mappings' includes duplicate entries after importing project with multiple views
+ - <!-- JAL-2781 JAL-2780 --> Viewing or annotating Uniprot protein sequences via SIFTS from associated PDB entries with negative residue numbers or missing residues fails
+ - <!-- JAL-2952 --> Exception when shading sequence with negative Temperature Factor values from annotated PDB files (e.g. as generated by CONSURF)
+ - <!-- JAL-2920 --> Uniprot 'sequence variant' features tooltip doesn't include a text description of mutation
+ - <!-- JAL-2922 --> Invert displayed features very slow when structure and/or overview windows are also shown
+ - <!-- JAL-2954 --> Selecting columns from highlighted regions very slow for alignments with large numbers of sequences
+ - <!-- JAL-2925 --> Copy Consensus fails for group consensus with 'StringIndexOutOfBounds'
+ - <!-- JAL-2976 --> VAqua(4) provided as fallback Look and Feel for OSX platforms running Java 10
+ - <!-- JAL-2960 --> Adding a structure to existing structure view appears to do nothing because the view is hidden behind the alignment view
+
+
+### Applet
+ - <!-- JAL-2926 --> Copy consensus sequence option in applet should copy the group consensus when popup is opened on it
+
+
+### Batch Mode
+ - <!-- JAL-2913 --> Fixed ID width preference is not respected
+
+
+### New Known Defects
+ - <!-- JAL-2973 --> Exceptions occasionally raised when editing a large alignment and overview is displayed
+ - <!-- JAL-2974 --> 'Overview updating' progress bar is shown repeatedly after a series of edits even when the overview is no longer reflecting updates
+ - <!-- JAL-2946 --> 'SIFTS Mapping Error' when viewing structures for protein subsequence (if 'Trim Retrieved Sequences' enabled) or Ensembl isoforms (Workaround in 2.10.4 is to fail back to N&W mapping)
+ - <!-- JAL-2990 --> Export Annotations from File Menu with CSV option gives blank output
