prepare v0.12.0 release

[jswrenn]

UPDATE: Changelog complete!

Still need to write changelog. Is there any way to easily get all PRs merged after a date/tag? Running this:

git log v0.11.0.. --reverse --merges --oneline --grep='Merge #' | cut -d' ' -f3 | sort -n 

Only turned up merge commits for:

• fix: take_while_inclusive takes iterator by value #709
• Add conversion into (Option<A>,Option<B>) to EitherOrBoth #713
• Add conversion from Either<A, B> to EitherOrBoth<A, B> #715
• Fix multiunzip documentation #718
• try_len method #723
• Fuse the iterator in LazyBuffer #727
• Powerset count #735
• Count combinations with replacement #737
• Complete Permutations::size_hint #739
• Do not sum options #745

But we have plenty more PRs that were merged without merge commits: https://github.com/rust-itertools/itertools/milestone/5?closed=1

I'm quite tempted to adopt a squash-before-merging approach before our next release to simplify this (so we could just list off all commits without too much noise).

git is an awesome command line tool but it can't have all the informations that github has. So I would look at the github API instead. ...Merged PRs since 2023-06-22 (date for v0.11.0):

• Web search: https://github.com/search?q=repo:rust-itertools/itertools+type:pr+merged:>2023-06-22
• The same in JSON: https://api.github.com/search/issues?q=repo:rust-itertools/itertools+type:pr+merged:>2023-06-22&per_page=100
• With curl and jq, assuming there are less than 100 results (there are 52 today), the entire list is:
  curl -H "Accept: application/vnd.github+json" https://api.github.com/search/issues?q=repo:rust-itertools/itertools+type:pr+merged:>2023-06-22&per_page=100 | jq ".items[].number"
  The json data holds way more informations such as jq ".items[].pull_request.merged_at" that could help sort them but I only knew about jq before this.

And after a quick search, an helpful git log --tags --simplify-by-decoration --pretty="format:%cs %d" | grep v0.11.0.
(Or with %cI) It could be used to merge this with the curl|jq command.

Thanks! Coming at this from a slightly different angle, running this:

git log v0.11.0.. --reverse --oneline \ | cut -d' ' -f1 \ | xargs -I {} gh pr list --search {} --state merged --json number \ | jq '.[] | .number' \ | sort -nu

I dived into jq to nicely sort merged PRs by the merged_at key and came with two git aliases:

pulls-after-date = "!f() { curl -H 'Accept: application/vnd.github+json' 'https://api.github.com/search/issues?per_page=100&q=repo:rust-itertools/itertools+type:pr+merged:>'$1 | jq '.items | sort_by(.pull_request.merged_at) | .[].number'; }; f" pulls-after-tag = "!f() { git pulls-after-date $(git log -1 --format=%as $1); }; f" # %aI would be more precise than %as but it contains a "+" that messes with the github url. 

Usage: git pulls-after-date 2023-06-22 or simply git pulls-after-tag v0.11.0.

Aliases v2: any github repo ; use more precise date with %aI instead of %as but url-escape the contained + to %2B.

# e.g. rust-itertools/itertools get-repo = "!f() { url=$(git remote get-url upstream); url=${url#'https://github.com/'}; url=${url%'.git'}; echo ${url}; }; f" # List (up to 100) merged PRs for the current GitHub repo. pulls-after-date = "!f() { date_for_url=${1/+/%2B}; curl -H 'Accept: application/vnd.github+json' 'https://api.github.com/search/issues?per_page=100&q=repo:'$(git get-repo)'+type:pr+merged:>'$date_for_url | jq '.items | sort_by(.pull_request.merged_at) | .[].number'; }; f" # Get the date for a given tag, then call the main alias. pulls-after-tag = "!f() { git pulls-after-date $(git log -1 --format=%aI $1); }; f"

Thanks for this. Looks good to me.

@jswrenn There is #![doc(html_root_url = "https://docs.rs/itertools/0.11/")] in lib.rs.

[jswrenn]

Whoops, I thought we deleted that.
