-
-#### 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.

-## 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-  - Removed an outdated part of the hint.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.

-
-#### 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.

-In the first function we are looping over the Vector and getting a reference to one `element` at a time.
+Hint 1: In the code, the variable `element` represents an item from the Vec as it is being iterated.
-To modify the value of that `element` we need to use the * dereference operator. You can learn more in this chapter of the Rust book:
