+Git v1.7.5.3 Release Notes
+==========================
+
+Fixes since v1.7.5.2
+--------------------
+
+ * The bash completion scripts should correctly work using zsh's bash
+   completion emulation layer now.
+
+ * Setting $(prefix) in config.mak did not affect where etc/gitconfig
+   file is read from, even though passing it from the command line of
+   $(MAKE) did.
+
+ * The logic to handle "&" (expand to UNIX username) in GECOS field
+   miscounted the length of the name it formatted.
+
+ * "git cherry-pick -s resolve" failed to cherry-pick a root commit.
+
+ * "git diff --word-diff" misbehaved when diff.suppress-blank-empty was
+   in effect.
+
+ * "git log --stdin path" with an input that has additional pathspec
+   used to corrupt memory.
+
+ * "git send-pack" (hence "git push") over smalt-HTTP protocol could
+   deadlock when the client side pack-object died early.
+
+ * Compressed tarball gitweb generates used to be made with the timestamp
+   of the tarball generation; this was bad because snapshot from the same
+   tree should result in a same tarball.
+
+And other minor fixes and documentation updates.

 test_description="Test the svn importer's input handling routines.
 
-These tests exercise the line_buffer library, but their real purpose
-is to check the assumptions that library makes of the platform's input
-routines.  Processes engaged in bi-directional communication would
-hang if fread or fgets is too greedy.
+These tests provide some simple checks that the line_buffer API
+behaves as advertised.
 
 While at it, check that input of newlines and null bytes are handled
 correctly.
