-# Upcoming release
-
-## Performance improvements
-
+# v8.7.0
 
 ## Features
 
+- Add flag --no-require-git to always respect gitignore files, see #1216 (@vegerot)
 
 ## Bugfixes
 
+- Fix logic for when to use global ignore file. There was a bug where the only case where the
+  global ignore file wasn't processed was if `--no-ignore` was passed, but neither `--unrestricted`
+  nor `--no-global-ignore-file` is passed. See #1209
+
+## Changes
+
+## Other
+
+# v8.6.0
+
+## Features
+
+- New `--and <pattern>` option to add additional patterns that must also be matched. See #315
+  and #1139 (@Uthar)
+- Added `--changed-after` as alias for `--changed-within`, to have a name consistent with `--changed-before`.
+
 
 ## Changes
 
+- Breaking: On Unix-like systems, `--type executable` now additionally checks if
+  the file is executable by the current user, see #1106 and #1169 (@ptipiak)
+
+
+## Bugfixes
+
+- Use fd instead of fd.exe for Powershell completions (when completions are generated on windows)
+
 
 ## Other
 
 
+# v8.5.3
+
+## Bugfixes
+
+- Fix completion generation to not include full path of fd command
+- Fix build error if completions feature is disabled
+
+# v8.5.2
+
+## Bugfixes
+
+- Fix --owner option value parsing, see #1163 and #1164 (@tmccombs)
+
+
+# v8.5.1
+
+## Bugfixes
+
+- Fix --threads/-j option value parsing, see #1160 and #1162 (@sharkdp)
+
+
+# v8.5.0
+
+## Features
+
+- `--type executable`/`-t` now works on Windows, see #1051 and #1061 (@tavianator)
+
+## Bugfixes
+
+- Fixed differences between piped / non-piped output. This changes `fd`s behavior back to what we
+  had before 8.3.0, i.e. there will be no leading `./` prefixes, unless `--exec`/`-x`,
+  `--exec-batch`/`-X`, or `--print0`/`-0` are used. `--strip-cwd-prefix` can be used to strip that
+  prefix in those cases. See #1046, #1115, and #1121 (@tavianator)
+- `fd` could previously crash with a panic due to a race condition in Rusts standard library
+  (see https://github.com/rust-lang/rust/issues/39364). This has been fixed by switching to a different
+  message passing implementation, see #1060 and #1146 (@tavianator)
+- `fd`s memory usage will not grow unboundedly on huge directory trees, see #1146 (@tavianator)
+- fd returns an error when current working directory does not exist while a search path is
+  specified, see #1072 (@vijfhoek)
+- Improved "command not found" error message, see #1083 and #1109 (@themkat)
+- Preserve command exit codes when using `--exec-batch`, see #1136 and #1137 (@amesgen)
+
+## Changes
+
+- No leading `./` prefix for non-interactive results, see above.
+- fd now colorizes paths in parallel, significantly improving performance, see #1148 (@tavianator)
+- fd can now avoid `stat` syscalls even when colorizing paths, as long as the color scheme doesn't
+  require metadata, see #1148 (@tavianator)
+- The statically linked `musl` versions of `fd` now use `jmalloc`, leading to a significant performance
+  improvement, see #1062 (@tavianator)
+
+## Other
+
+- Added link back to GitHub in man page and `--help` text, see #1086 (@scottchiefbaker)
+- Major update in how `fd` handles command line options internally, see #1067 (@tmccombs)
+
+# v8.4.0
+
+## Features
+
+- Support multiple `--exec <cmd>` instances, see #406 and #960 (@tmccombs)
+
+## Bugfixes
+
+- "Argument list too long" errors can not appear anymore when using `--exec-batch`/`-X`, as the command invocations are automatically batched at the maximum possible size, even if `--batch-size` is not given. See #410 and #1020 (@tavianator)
+
+## Changes
+
+- Directories are now printed with an additional path separator at the end: `foo/bar/`, see #436 and #812 (@yyogo)
+- The `-u` flag was changed to be equivalent to `-HI` (previously, a single `-u` was only equivalent to `-I`). Additional `-u` flags are still allowed, but ignored. See #840 and #986 (@jacksontheel)
+
+## Other
+
+- Added installation instructions for RHEL8, see #989 (@ethsol)
+
+

+# Release checklist
+
+This file can be used as-is, or copied into the GitHub PR description which includes
+necessary changes for the upcoming release.
+
+## Version bump
+
+- [ ] Create a new branch for the required changes for this release.
+- [ ] Update version in `Cargo.toml`. Run `cargo build` to update `Cargo.lock`.
+      Make sure to `git add` the `Cargo.lock` changes as well.
+- [ ] Find the current min. supported Rust version by running
+      `grep '^\s*MIN_SUPPORTED_RUST_VERSION' .github/workflows/CICD.yml`.
+- [ ] Update the `fd` version and the min. supported Rust version in `README.md`.
+- [ ] Update `CHANGELOG.md`. Change the heading of the *"Upcoming release"* section
+      to the version of this release.
+
+## Pre-release checks and updates
+
+- [ ] Install the latest version (`cargo install --locked -f --path .`) and make
+      sure that it is available on the `PATH` (`fd --version` should show the
+      new version).
+- [ ] Review `-h`, `--help`, and the `man` page.
+- [ ] Run `fd -h` and copy the output to the *"Command-line options"* section in
+      the README
+- [ ] Push all changes and wait for CI to succeed (before continuing with the
+      next section).
+- [ ] Optional: manually test the new features and command-line options described
+      in the `CHANGELOG.md`.
+- [ ] Run `cargo publish --dry-run` to make sure that it will succeed later
+      (after creating the GitHub release).
+
+## Release
+
+- [ ] Merge your release branch (should be a fast-forward merge).
+- [ ] Create a tag and push it: `git tag vX.Y.Z; git push origin tag vX.Y.Z`.
+      This will trigger the deployment via GitHub Actions.
+      REMINDER: If your `origin` is a fork, don't forget to push to e.g. `upstream`
+      instead.
+- [ ] Go to https://github.com/sharkdp/fd/releases/new to create the new
+      release. Select the new tag and also use it as the release title. For the
+      release notes, copy the corresponding section from `CHANGELOG.md` and
+      possibly add additional remarks for package maintainers.
+      Publish the release.
+- [ ] Check if the binary deployment works (archives and Debian packages should
+      appear when the CI run *for the Git tag* has finished).
+- [ ] Publish to crates.io by running `cargo publish` in a *clean* repository.
+      One way to do this is to clone a fresh copy.
+
+## Post-release
+
+- [ ] Prepare a new *"Upcoming release"* section at the top of `CHANGELOG.md`.
+      Put this at the top:
