1 GIT v1.5.2 Release Notes (draft)
2 ========================
4 Updates since v1.5.1
5 --------------------
7 * Plumbing level subproject support.
9 You can include a subdirectory that has an independent git
10 repository in your index and tree objects as a
11 "subproject". This plumbing (i.e. "core") level subproject
12 support explicitly excludes recursive behaviour.
14 The "subproject" entries in the index and trees are
15 incompatible with older versions of git. Experimenting with
16 the plumbing level support is encouraged, but be warned that
17 unless everybody in your project updates to this release or
18 later, using this feature would make your project
19 inaccessible by people with older versions of git.
21 * Plumbing level gitattributes support.
23 The gitattributes mechanism allows you to add 'attributes' to
24 paths in your project, and affect the way certain git
25 operations work. Currently you can influence if a path is
26 considered a binary or text (the former would be treated by
27 'git diff' not to produce textual output; the latter can go
28 through the line endings conversion process in repositories
29 with core.autocrlf set), and specify a custom 3-way merge
30 driver.
32 * The packfile format now optionally suports 64-bit index.
34 This release supports the "version 2" format of the .idx
35 file. This is automatically enabled when a huge packfile
36 needs more than 32-bit to express offsets of objects in the
37 pack
39 * New commands and options.
41 - "git bisect start" can optionally take a single bad commit and
42 zero or more good commits on the command line.
44 - "git shortlog" can optionally be told to wrap its output.
46 - "subtree" merge strategy allows another project to be merged in as
47 your subdirectory.
49 - "git format-patch" learned a new --subject-prefix=<string>
50 option, to override the built-in "[PATCH]".
52 - "git add -u" is a quick way to do the first stage of "git
53 commit -a" (i.e. update the index to match the working
54 tree); it obviously does not make a commit.
56 * Updated behavior of existing commands.
58 - "git diff --stat" shows size of preimage and postimage blobs
59 for binary contents. Earlier it only said "Bin".
61 - "git lost-found" shows stuff that are unreachable except
62 from reflogs.
64 - "git checkout branch^0" now detaches HEAD at the tip commit
65 on the named branch, instead of just switching to the
66 branch (use "git checkout branch" to switch to the branch,
67 as before).
69 - "git bisect next" can be used after giving only a bad commit
70 without giving a good one (this starts bisection half-way to
71 the root commit). We used to refuse to operate without a
72 good and a bad commit.
74 - "git push", when pushing into more than one repository, does
75 not stop at the first error.
77 - "git archive" does not insist you to give --format parameter
78 anymore; it defaults to "tar".
80 - "git cvsserver" can use backends other than sqlite.
82 - "gitview" (in contrib/ section) learned to better support
83 "git-annotate".
85 - Local "git fetch" from a repository whose object store is
86 one of the alternates (e.g. fetching from the origin in a
87 repository created with "git clone -l -s") avoids
88 downloading objects unnecessary.
90 * Builds
92 - git-p4import has never been installed; now there is an
93 installation option to do so.
95 - gitk and git-gui can be configured out.
97 - Generated documentation pages automatically get version
98 information from GIT_VERSION
100 - Parallel build with "make -j" descending into subdirectory
101 was fixed.
103 * Performance Tweaks
105 - optimized "git-rev-list --bisect" (hence "git-bisect").
107 - optimized "git-add $path" in a large directory, most of
108 whose contents are ignored.
111 Fixes since v1.5.1
112 ------------------
114 All of the fixes in v1.5.1 maintenance series are included in
115 this release, unless otherwise noted.
117 * Bugfixes
119 - Switching branches with "git checkout" refused to work when
120 a path changes from a file to a directory between the
121 current branch and the new branch, in order not to lose
122 possible local changes in the directory that is being turned
123 into a file with the switch. We now allow such a branch
124 switch after making sure that there is no locally modified
125 file nor un-ignored file in the directory. This has not
126 been backported to 1.5.1.x series, as it is rather an
127 intrusive change.
129 - Merging branches that have a file in one and a directory in
130 another at the same path used to get quite confused. We
131 handle such a case a bit more carefully, even though that is
132 still left as a conflict for the user to sort out. This
133 will not be backported to 1.5.1.x series, as it is rather an
134 intrusive change.
136 * Documentation updates
138 * Performance Tweaks
