+Git v1.8.4.1 Release Notes
+========================
+
+Fixes since v1.8.4
+------------------
+
+ * Some people still use rather old versions of bash, which cannot
+   grok some constructs like 'printf -v varname' the prompt and
+   completion code started to use recently.  The completion and
+   prompt scripts have been adjusted to work better with these old
+   versions of bash.
+
+ * "git rebase -i" had a minor bug (the same could be in other
+   programs, as the root cause is pretty generic) where the code
+   feeds a random, data dependeant string to 'echo' and expects it
+   to come out literally.
+
+ * "submodule.<name>.path" variable mistakenly set to the empty
+   "true" caused the configuration parser to segfault.
+
+ * Output from "git log --full-diff -- <pathspec>" looked strange,
+   because comparison was done with the previous ancestor that
+   touched the specified <pathspec>, causing the patches for paths
+   outside the pathspec to show more than the single commit has
+   changed.
+
+ * The auto-tag-following code in "git fetch" tries to reuse the
+   same transport twice when the serving end does not cooperate and
+   does not give tags that point to commits that are asked for as
+   part of the primary transfer.  Unfortunately, Git-aware transport
+   helper interface is not designed to be used more than once, hence
+   this did not work over smart-http transfer.  Fixed.
+
+ * Send a large request to read(2)/write(2) as a smaller but still
+   reasonably large chunks, which would improve the latency when the
+   operation needs to be killed and incidentally works around broken
+   64-bit systems that cannot take a 2GB write or read in one go.
+
+ * A ".mailmap" file that ends with an incomplete line, when read
+   from a blob, was not handled properly.
+
+ * The recent "short-cut clone connectivity check" topic broke a
+   shallow repository when a fetch operation tries to auto-follow
+   tags.
+
+ * On platforms with fgetc() and friends defined as macros,
+   the configuration parser did not compile.
+
+Also contains a handful of trivial code clean-ups, documentation
+updates, updates to the test suite, etc.
