# Note that the "Deploy to Github Pages" step won't run in this mode,

pull_request:
# Whenever something gets pushed to main, update the docs!
# This is great for getting docs changes live without cutting a full release.
#
# Note that if you're using cargo-dist, this will "race" the Release workflow
# that actually builds the Github Release that oranda tries to read (and
# this will almost certainly complete first). As a result you will publish
# docs for the latest commit but the oranda landing page won't know about
# the latest release. The workflow_run trigger below will properly wait for
# cargo-dist, and so this half-published state will only last for ~10 minutes.
#
# If you only want docs to update with releases, disable this, or change it to
# a "release" branch. You can, of course, also manually trigger a workflow run
# when you want the docs to update.

# Whenever a workflow called "Release" completes, update the docs!

# If you're using cargo-dist, this is recommended, as it will ensure that

# however that Github's UI is wonky when you use workflow_run, and won't
# show this workflow as part of any commit. You have to go to the "actions"
# tab for your repo to see this one running (the gh-pages deploy will also

<a name="5.6.1"></a>
## 5.6.1 (2023-09-18)
#### Changed
- Converted all exercises with assertions to test mode.
#### Fixed
- `cow1`: Reverted regression introduced by calling `to_mut` where it
shouldn't have been called, and clarified comment.
- `primitive_types3`: Require at least an array of 100 elements.
- Removed hint comments when no hint exists for the exercise.
- `as_ref_mut`: Fixed a typo in a test function name.
- `enums3`: Fixed formatting with `rustfmt`.
<a name="5.6.0"></a>
## 5.6.0 (2023-09-04)
#### Added
- New exercise: `if3`, teaching the user about `if let` statements.
- `hashmaps2`: Added an extra test function to check if the amount of fruits is higher than zero.
- `enums3`: Added a test for `Message`.
- `if1`: Added a test case to check equal values.
- `if3`: Added a note specifying that there are no test changes needed.
#### Changed
- Swapped the order of threads and smart pointer exercises.
- Rewrote the CLI to use `clap` - it's matured much since we switched to `argh` :)
- `structs3`: Switched from i32 to u32.
- `move_semantics`: Switched 1-4 to tests, and rewrote them to be way simpler, while still teaching about the same
concepts.
#### Fixed
- `iterators5`:
- Removed an outdated part of the hint.
- Renamed variables to use snake_case.
- `vecs2`: Updated the hint to reference the renamed loop variable.
- `enums3`: Changed message string in test so that it gets properly tested.
- `strings2`: Corrected line number in hint, then removed it (this both happened as part of this release cycle).
- `primitive_types4`: Updated hint to the correct ending index.
- `quiz1`: Removed duplicated sentence from exercise comments.
- `errors4`: Improved comment.
- `from_into`: Fixed test values.
- `cow1`: Added `.to_mut()` to distinguish from the previous test case.
- `threads2`: Updated hint text to reference the correct book heading.
#### Housekeeping
- Cleaned up the explanation paragraphs at the start of each exercise.
- Lots of Nix housekeeping that I don't feel qualified to write about!
- Improved CI workflows, we're now testing on multiple platforms at once.
