## Notable changes

**Symfony Bundle**

A bundle is now available for Symfony applications, it will ease the integration
and usage of the Valinor library in the framework. The documentation can be 
found in the [CuyZ/Valinor-Bundle] repository.

Note that [the documentation has been updated] to add information about the bundle
as well as tips on how to integrate the library in other frameworks.

**PHP 8.3 support**

Thanks to [@TimWolla], the library now supports PHP 8.3, which entered its beta
phase. Do not hesitate to test the library with this new version, and [report any
encountered issue on the repository].

**Better type parsing**

The first layer of the type parser has been completely rewritten. The previous
one would use regex to split a raw type in tokens, but that led to limitations —
mostly concerning quoted strings — that are now fixed.

Although this change should not impact the end user, it is a major change in the
library, and it is possible that some edge cases were not covered by tests. If
that happens, please [report any encountered issue on the repository].

Example of previous limitations, now solved:

```php
// Union of strings containing space chars
(new MapperBuilder())
    ->mapper()
    ->map(
        "'foo bar'|'baz fiz'",
        'baz fiz'
    );

// Shaped array with special chars in the key
(new MapperBuilder())
    ->mapper()
    ->map(
        "array{'some & key': string}",
        ['some & key' => 'value']
    );
```

**More advanced array-key handling**

It is now possible to use any string or integer as an array key. The following
types are now accepted and will work properly with the mapper:

```php
$mapper->map("array<'foo'|'bar', string>", ['foo' => 'foo']);

$mapper->map('array<42|1337, string>', [42 => 'foo']);

$mapper->map('array<positive-int, string>', [42 => 'foo']);

$mapper->map('array<negative-int, string>', [-42 => 'foo']);

$mapper->map('array<int<-42, 1337>, string>', [42 => 'foo']);

$mapper->map('array<non-empty-string, string>', ['foo' => 'foo']);

$mapper->map('array<class-string, string>', ['SomeClass' => 'foo']);
```
