 [New Topics]
 
-* jc/t1512-fix (2013-07-01) 2 commits
- - get_short_sha1(): correctly disambiguate type-limited abbreviation
- - t1512: correct leftover constants from earlier edition
+* bc/push-match-many-refs (2013-07-08) 1 commit
+ - remote.c: avoid O(m*n) behavior in match_push_refs
 
- A test that should have failed but didn't revealed a bug that needs
- to be corrected.
+ Pushing to repositories with many refs employed O(m*n) algorithm
+ where n is the number of refs on the receiving end.

- Fetching between repositories with many refs employed O(n^2)
- algorithm to match up the common objects, which has been corrected.
+ Will merge to 'master'.
+
+
+* jc/name-rev-exact-ref (2013-07-09) 3 commits
+ - describe: use argv-array
+ - name-rev: allow converting the exact object name at the tip of a ref
+ - name-ref: factor out name shortening logic from name_ref()
+
+ Corrects the longstanding sloppiness in the implementation of
+ name-rev that conflated "we take commit-ish" and "differences
+ between tags and commits do not matter".
 
  Will merge to 'next'.
 
 
-* jk/format-patch-from (2013-07-03) 2 commits

- - pretty.c: drop const-ness from pretty_print_context

+ - pack-revindex: radix-sort the revindex
+ - cat-file: add --batch-disk-sizes option
+ - teach sha1_object_info_extended a "disk_size" query
+ - zero-initialize object_info structs
 
- "git format-patch" learned "--from[=whom]" option, which sets the
- "From: " header to the specified person (or the person who runs the
- command, if "=whom" part is missing) and move the original author
- information to an in-body From: header as necessary.
+ Allow on-disk footprint of objects in packfiles (often they are a
+ lot smaller than their true size, when expressed as deltas).  The
+ command line API to ask for the new extra information may be still

+ - clone: drop connectivity check for local clones
+ (this branch is used by jk/clone-shared-no-connectivity-validation.)
+
+ "git clone -s/-l" is a filesystem level copy and does not offer any
+ protection against source repository being corrupt.  While the
+ connectivity validation checks commits and trees being readable, it
+ made the otherwise instantaneous local modes of clone much more
+ expensive, without protecting blob data from bitflips.
