1 GIT v1.5.3 Release Notes (draft)
2 ========================
3
4 Updates since v1.5.2
5 --------------------
6
7 * An initial interation of Porcelain level superproject support
8 started to take shape.
9
10 * Thee are a handful pack-objects changes to help you cope better with
11 repositories with pathologically large blobs in them.
12
13 * New commands and options.
14
15 - "git-submodule" command helps you manage the projects from
16 the superproject that contain them.
17
18 - In addition to core.compression configuration option,
19 core.loosecompression and pack.compression options can
20 independently tweak zlib compression levels used for loose
21 and packed objects.
22
23 - "git-ls-tree -l" shows size of blobs pointed at by the
24 tree entries, similar to "/bin/ls -l".
25
26 - "git-rev-list" learned --regexp-ignore-case and
27 --extended-regexp options to tweak its matching logic used
28 for --grep fitering.
29
30 - "git-describe --contains" is a handier way to call more
31 obscure command "git-name-rev --tags".
32
33 - "git gc --aggressive" tells the command to spend more cycles
34 to optimize the repository harder.
35
36 - "git repack" can be told to split resulting packs to avoid
37 exceeding limit specified with "--max-pack-size".
38
39 * Updated behavior of existing commands.
40
41 - "git push" pretends that you immediately fetched back from
42 the remote by updating corresponding remote tracking
43 branches if you have any.
44
45 - The diffstat given after a merge (or a pull) honors the
46 color.diff configuration.
47
48 - "git-apply --whitespace=strip" removes blank lines added at
49 the end of the file.
50
51 - fetch over git native protocols with -v shows connection
52 status, and the IP address of the other end, to help
53 diagnosing problems.
54
55 - core.legacyheaders is no more, although we still can read
56 objects created in a new loose object format.
57
58 - "git-mailsplit" (hence "git-am") can read from Maildir
59 formatted mailboxes.
60
61 - "git cvsserver" does not barf upon seeing "cvs login"
62 request.
63
64 - "pack-objects" honors "delta" attribute set in
65 .gitattributes. It does not attempt to deltify blobs that
66 come from paths with delta attribute set to false.
67
68 - new-workdir script (in contrib) can now be used with a bare
69 repository.
70
71
72 * Builds
73
74 -
75
76 * Performance Tweaks
77
78 - git-pack-objects avoids re-deltification cost by caching
79 small enough delta results it creates while looking for the
80 best delta candidates.
81
82 - diff-delta code that is used for packing has been improved
83 to work better on big files.
84
85 - when there are more than one pack files in the repository,
86 the runtime used to try finding an object always from the
87 newest packfile; it now tries the same packfile as we found
88 the object requested the last time, which exploits the
89 locality of references.

91 Fixes since v1.5.2
92 ------------------
93
94 All of the fixes in v1.5.2 maintenance series are included in
95 this release, unless otherwise noted.
96
97 * Bugfixes
98
99 - .... This has not
100 been backported to 1.5.2.x series, as it is rather an
101 intrusive change.
