* Changes in Specialized Modes and Packages in Emacs 24.2
+** Diff mode
+
+Faces for changes now use the same diff color scheme as in modern VCSes
+where deletions are displayed in red (new faces `diff-refine-removed'
+and `smerge-refined-removed' and new definition of `diff-removed'),
+insertions in green (new faces `diff-refine-added' and
+`smerge-refined-added' and new definition of `diff-added').
+The variable `diff-use-changed-face' defines whether to use
+the face `diff-changed', or `diff-removed' and `diff-added'
+to highlight changes in context diffs.
+
** `sh-script'
*** Pairing of parens/quotes uses electric-pair-mode instead of skeleton-pair.
*** `sh-electric-here-document-mode' now controls auto-insertion of here-docs.
+2012-05-25 Juri Linkov <juri@jurta.org>
+
+ Use the same diff color scheme as in modern VCSes (bug#10181).
+
+ * vc/diff-mode.el (diff-header, diff-file-header): Remove "green"
+ to avoid confusion with `diff-added' that now uses green colors.
+ (diff-removed): Use shades of red.
+ (diff-added): Use shades of green.
+ (diff-changed): Leave just the yellow color.
+ (diff-use-changed-face): New variable.
+ (diff-font-lock-keywords): Use `diff-use-changed-face' to decide
+ how to highlight context diff changes.
+ (diff-refine-change): Use shades of yellow.
+ (diff-refine-removed): New face that uses shades of red.
+ (diff-refine-added): New face that uses shades of green.
+ (diff-refine-hunk): Use `diff-refine-change', `diff-refine-added',
+ `diff-refine-removed' in the call to `smerge-refine-subst'
+ depending on the value of `diff-use-changed-face'.
+
+ * vc/smerge-mode.el (smerge-mine): Use shades of red.
+ (smerge-other): Use shades of green.
+ (smerge-base): Use shades of yellow.
+ (smerge-refined-change): Empty face.
+ (smerge-refined-removed): New face that uses shades of red.
+ (smerge-refined-added): New face that uses shades of green.
+ (smerge-refine-subst): Rename arg `props' to `props-c'. Add new
+ args `props-r' and `props-a', and use them. Doc fix.
+ (smerge-refine): Evaluate `smerge-use-changed-face' and depending
+ on its value use different faces `smerge-refined-change',
+ `smerge-refined-removed', `smerge-refined-added' in the call to
+ `smerge-refine-subst'.
+
+ * vc/ediff-init.el (ediff-current-diff-A, ediff-fine-diff-A):
+ Add face condition `min-colors 88' with shades of red.
+ (ediff-current-diff-B, ediff-fine-diff-B): Add face condition
+ `min-colors 88' with shades of green.
+ (ediff-current-diff-C, ediff-fine-diff-C): Add face condition
+ `min-colors 88' with shades of yellow.
+
2012-05-24 Glenn Morris <rgm@gnu.org>
* paths.el (prune-directory-list, remote-shell-program): Move to...
