1 Git v1.7.10 Release Notes
2 =========================
3
4 Updates since v1.7.9
5 --------------------
6
7 UI, Workflows & Features
8
9 * Improved handling of views, labels and branches in git-p4 (in contrib).
10
11 * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
12 support incremental imports.
13
14 * "git am" learned to pass "-b" option to underlying "git mailinfo", so
15 that bracketed string other than "PATCH" at the beginning can be kept.
16
17 * "git clone" learned "--single-branch" option to limit cloning to a
18 single branch (surprise!).
19
20 * "git clone" learned to detach the HEAD in the resulting repository
21 when the source repository's HEAD does not point to a branch.
22
23 * When showing a patch while ignoring whitespace changes, the context
24 lines are taken from the postimage, in order to make it easier to
25 view the output.
26
27 * "git merge" in an interactive session learned to spawn the editor
28 by default to let the user edit the auto-generated merge message,
29 to encourage people to explain their merges better. Legacy scripts
30 can export MERGE_AUTOEDIT=no to retain the historical behaviour.
31
32 * "gitweb" allows intermediate entries in the directory hierarchy
33 that leads to a projects to be clicked, which in turn shows the
34 list of projects inside that directory.
35
36 Performance
37
38 * During "git upload-pack" in respose to "git fetch", unnecessary calls
39 to parse_object() have been eliminated, to help performance in
40 repositories with excessive number of refs.
41
42 Internal Implementation
43
44 * Recursive call chains in "git index-pack" to deal with long delta
45 chains have been flattened, to reduce the stack footprint.
46
47 * Use of add_extra_ref() API is slowly getting removed, to make it
48 possible to cleanly restructure the overall refs API.
49
50 * The test suite supports the new "test_pause" helper function.
51
52 * t/Makefile is adjusted to prevent newer versions of GNU make from
53 running tests in seemingly random order.
54
55 Also contains minor documentation updates and code clean-ups.

58 Fixes since v1.7.9
59 ------------------
60
61 Unless otherwise noted, all the fixes since v1.7.9 in the maintenance
62 releases are contained in this release (see release notes to them for
63 details).
64
65 * "add -e" learned not to show a diff for an otherwise unmodified
66 submodule that only has uncommitted local changes in the patch
67 prepared by for the user to edit.
68 (merge 701825d js/add-e-submodule-fix later to maint).
69
70 * "rebase" and "commit --amend" failed to work on commits with ancient
71 timestamps near year 1970.
72 (merge 2c733fb jc/parse-date-raw later to maint).
73
74 * "git merge --ff-only $tag" failed because it cannot record the
75 required mergetag without creating a merge, but this is so common
76 operation for branch that is used _only_ to follow the upstream, so
77 it is allowed to fast-forward without recording the mergetag.
78 (merge b5c9f1c jc/merge-ff-only-stronger-than-signed-merge later to maint).
79
80 * Typo in "git branch --edit-description my-tpoic" was not diagnosed.
81 (merge c2d17ba jc/branch-desc-typoavoidance later to maint).
82
83 * rpmbuild noticed an unpackaged but installed *.mo file and failed.
84 (merge 3a9f58c jn/rpm-spec later to maint).
