Git v2.1 Release Notes
======================
+Backward compatibility notes
+----------------------------
+
+ * The default value we give to the environment variable LESS has been
+ changed from "FRSX" to "FRX", losing "S" (chop long lines instead
+ of wrapping). Existing users who prefer not to see line-wrapped
+ output may want to set
+
+ $ git config core.pager "less -S"
+
+ to restore the traditional behaviour. It is expected that people
+ find output from the most subcommands easier to read with the new
+ default, except for "blame" which tends to produce really long
+ lines. To override the new default only for "git blame", you can
+ do this:
+
+ $ git config pager.blame "less -S"
+
+ * A few disused directories in contrib/ have been retired.
+

Updates since v2.0
------------------
UI, Workflows & Features
+ * Since the very beginning of Git, we gave the LESS environment a
+ default value "FRSX" when we spawn "less" as the pager. "S" (chop
+ long lines instead of wrapping) has been removed from this default
+ set of options, because it is more or less a personal taste thing,
+ as opposed to others that have good justifications (i.e. "R" is
+ very much justified because many kinds of output we produce are
+ colored and "FX" is justified because output we produce is often
+ shorter than a page).
+
+ * The logic and data used to compute the display width needed for
+ UTF-8 strings have been updated to match Unicode 6.3 better.
+
* "git commit --date=<date>" option learned to read from more
timestamp formats, including "--date=now".
+ * The `core.commentChar` configuration variable is used to specify a
+ custom comment character other than the default "#" to be used in
+ the commit log editor. This can be set to `auto` to attempt to
+ choose a different character that does not conflict with what
+ already starts a line in the message being edited for cases like
+ "git commit --amend".
+
* "git grep" learned grep.fullname configuration variable to force
"--full-name" to be default. This may cause regressions on
scripted users that do not expect this new behaviour.
+ * "git imap-send" learned to ask the credential helper for auth
+ material.
+
* "git merge" without argument, even when there is an upstream
defined for the current branch, refused to run until
merge.defaultToUpstream is set to true. Flip the default of that
