 # Changes
 
+## 4.0.0
+
+- Removed `TryFrom` impls for `&Bytes` and `&[u8]` types. The only conversion
+  is possible from `&str` now. Changed the validation to use `&str` instead of
+  `&[u8]`. The main reason I made this change is that it makes no sense to
+  convert from a ASCII-encoded `&[u8]` not have it as `&str`. The conversion
+  can alerady be done with `from_utf8()`, no need to repeat it there.

 # trid - Turkish Citizenship ID Number crate
 
 This is my first ever written Rust code derived from my own [TurkishId](https://github.com/ssg/TurkishId)
-package for .NET. I'm trying to use existing code as an excuse to learn about Rust. Despite constant tackling
-with error messages, Rust has been extremely impressive so far. (How cool are doc-tests!?)

 # Usage
 
 The crate provides `TurkishId` type that represents a valid Turkish ID number. It can be instantiated
-from a string using its `parse()` method, or directly converted from a `u8` slice using `from()` or
-`try_from()` methods. The type guarantess that it never contains an invalid number, so there's no need
-to validate a `TurkishId` type.
+from a string using the `parse()` method of `str` type. `TurkishId` type guarantess that it never contains an invalid Turkish ID number, so there's no need to validate a `TurkishId` once parsed. It
+can always be passed around.
 
 The crate also provides `is_valid(value: &str)` function for validating ID numbers.
 
+The type occupies 11 bytes in memory and kept as ASCII representation of the number.
