1 Git 2.21 Release Notes
2 ======================
4 Backward Compatibility Notes
5 ----------------------------
8 Updates since v2.20
9 -------------------
11 UI, Workflows & Features
13 * The "http.version" configuration variable can be used with recent
14 enough cURL library to force the version of HTTP used to talk when
15 fetching and pushing.
17 * Small fixes and features for fast-export and fast-import, mostly on
18 the fast-export side.
20 * "git push $there $src:$dst" rejects when $dst is not a fully
21 qualified refname and not clear what the end user meant. The
22 codepath has been taught to give a clearer error message, and also
23 guess where the push should go by taking the type of the pushed
24 object into account (e.g. a tag object would want to go under
25 refs/tags/).
28 Performance, Internal Implementation, Development Support etc.
30 * Code clean-up with optimization for the codepath that checks
31 (non-)existence of loose objects.
33 * More codepaths become aware of working with in-core repository
34 instance other than the default "the_repository".
37 Fixes since v2.20
38 -----------------
40 * Updates for corner cases in merge-recursive.
41 (merge cc4cb0902c en/merge-path-collision later to maint).
43 * "git checkout frotz" (without any double-dash) avoids ambiguity by
44 making sure 'frotz' cannot be interpreted as a revision and as a
45 path at the same time. This safety has been updated to check also
46 a unique remote-tracking branch 'frotz' in a remote, when dwimming
47 to create a local branch 'frotz' out of a remote-tracking branch
48 'frotz' from a remote.
49 (merge be4908f103 nd/checkout-dwim-fix later to maint).
51 * Refspecs configured with "git -c var=val clone" did not propagate
52 to the resulting repository, which has been corrected.
53 (merge 7eae4a3ac4 sg/clone-initial-fetch-configuration later to maint).
55 * A properly configured username/email is required under
56 user.useConfigOnly in order to create commits; now "git stash"
57 (even though it creates commit objects to represent stash entries)
58 command is exempt from the requirement.
59 (merge 3bc2111fc2 sd/stash-wo-user-name later to maint).
61 * The http-backend CGI process did not correctly clean up the child
62 processes it spawns to run upload-pack etc. when it dies itself,
63 which has been corrected.
64 (merge 02818a98d7 mk/http-backend-kill-children-before-exit later to maint).
66 * Code cleanup, docfix, build fix, etc.
