Here are the topics that have been cooking. Commits prefixed with '-' are only in 'pu' (proposed updates) while commits prefixed with '+' are in 'next'. The ones marked with '.' do not appear in any of the integration branches, but I am still holding onto them. The third batch of topics are now in 'master'. You can find the changes described here in the integration branches of the repositories listed at http://git-blame.blogspot.com/p/git-public-repositories.html -------------------------------------------------- [Graduated to "master"] * dl/python-2.7-is-the-floor-version (2020-06-08) 1 commit (merged to 'next' on 2020-06-10 at ad3269ff40) + CodingGuidelines: specify Python 2.7 is the oldest version Document that we do not support Python 2.6 or older. * dl/t-readme-spell-git-correctly (2020-06-08) 1 commit (merged to 'next' on 2020-06-10 at 60144a59ed) + t/README: avoid poor-man's small caps GIT Doc updates. * en/do-match-pathspec-fix (2020-06-05) 1 commit (merged to 'next' on 2020-06-10 at 2e63c8c0fc) + dir: fix treatment of negated pathspecs Use of negative pathspec, while collecting paths including untracked ones in the working tree, was broken. * en/sparse-checkout (2020-06-05) 1 commit (merged to 'next' on 2020-06-10 at 697a10b031) + sparse-checkout: avoid staging deletions of all files The behaviour of "sparse-checkout" in the state "git clone --no-checkout" left was changed accidentally in 2.27, which has been corrected. * es/advertise-contribution-doc (2020-06-08) 1 commit (merged to 'next' on 2020-06-10 at c72c7da667) + docs: mention MyFirstContribution in more places Doc updates. * hn/refs-cleanup (2020-06-09) 6 commits (merged to 'next' on 2020-06-09 at abb59f83a2) + reftable: define version 2 of the spec to accomodate SHA256 + reftable: clarify how empty tables should be written + reftable: file format documentation + refs: improve documentation for ref iterator + t: use update-ref and show-ref to reading/writing refs + refs.h: clarify reflog iteration order (this branch is used by hn/reftable.)
