1 Git v2.1 Release Notes
2 ======================
4 Updates since v2.0
5 ------------------
7 UI, Workflows & Features
9 * "git commit --date=<date>" option learned to read from more
10 timestamp formats, including "--date=now".
12 * "git grep" learned grep.fullname configuration variable to force
13 "--full-name" to be default. This may cause regressions on
14 scripted users that do not expect this new behaviour.
16 * "git merge" without argument, even when there is an upstream
17 defined for the current branch, refused to run until
18 merge.defaultToUpstream is set to true. Flip the default of that
19 configuration variable to true.
21 * "git mergetool" learned to drive the vimdiff3 backend.
23 * mergetool.prompt used to default to 'true', always asking "do you
24 really want to run the tool on this path?". Among the two
25 purposes this prompt serves, ignore the use case to confirm that
26 the user wants to view particular path with the named tool, and
27 redefine the meaning of the prompt only to confirm the choice of
28 the tool made by the autodetection (for those who configured the
29 tool explicitly, the prompt shown for the latter purpose is
30 simply annoying).
32 Strictly speaking, this is a backward incompatible change and the
33 users need to explicitly set the variable to 'true' if they want
34 to resurrect the now-ignored use case.
36 * "git svn" learned to cope with malformed timestamps with only one
37 digit in the hour part, e.g. 2014-01-07T5:01:02.048176Z, emitted
38 by some broken subversion server implementations.
41 Performance, Internal Implementation, etc.
43 * "git diff" that compares 3-or-more trees (e.g. parents and the
44 result of a merge) have been optimized.
46 * The API to update/delete references are being converted to handle
47 updates to multiple references in a transactional way. As an
48 example, "update-ref --stdin [-z]" has been updated to use this
49 API.
52 Also contains various documentation updates and code clean-ups.
55 Fixes since v2.0
56 ----------------
58 Unless otherwise noted, all the fixes since v2.0 in the maintenance
59 track are contained in this release (see the maintenance releases'
60 notes for details).
62 * "--ignore-space-change" option of "git apply" ignored the spaces
63 at the beginning of line too aggressively, which is inconsistent
64 with the option of the same name "diff" and "git diff" have.
65 (merge 14d3bb4 jc/apply-ignore-whitespace later to maint).
67 * "git blame" miscounted number of columns needed to show localized
68 timestamps, resulting in jaggy left-side-edge of the source code
69 lines in its output.
70 (merge dd75553 jx/blame-align-relative-time later to maint).
72 * We used to disable threaded "git index-pack" on platforms without
73 thread-safe pread(); use a different workaround for such
74 platforms to allow threaded "git index-pack".
75 (merge 3953949 nd/index-pack-one-fd-per-thread later to maint).
77 * "git rerere forget" did not work well when merge.conflictstyle
78 was set to a non-default value.
79 (merge de3d8bb fc/rerere-conflict-style later to maint).
81 * "git status", even though it is a read-only operation, tries to
82 update the index with refreshed lstat(2) info to optimize future
83 accesses to the working tree opportunistically, but this could
84 race with a "read-write" operation that modify the index while it
85 is running. Detect such a race and avoid overwriting the index.
86 (merge 426ddee ym/fix-opportunistic-index-update-race later to maint).
