### 5.4.26 (2019-11-05)

- disable "Bootup::filterRequestUri()" && "Bootup::filterRequestInputs()" by default
      
      Since version 5.4.26 this library will NOT force "UTF-8" by "bootstrap.php" anymore.
      If you need to enable this behavior you can define "PORTABLE_UTF8__ENABLE_AUTO_FILTER", 
      before requiring the autoloader.
      
      ```
      define('PORTABLE_UTF8__ENABLE_AUTO_FILTER', 1);
      ```
      
      Before version 5.4.26 this behavior was enabled by default and you could disable it via "PORTABLE_UTF8__DISABLE_AUTO_FILTER", but the code had potential security vulnerabilities via injecting code while redirecting via ```header('Location ...```.
      This is the reason I decided to add this BC in a bug fix release, so that everybody using the current version will receive the security-fix.

### 5.4.25 (2019-10-14)

- update vendor (ASCII) lib

### 5.4.24 (2019-10-06)

- improve performance from "UTF8::UTF8::str_titleize_for_humans()" (use "array_merge" only if needed)
- improve performance from "UTF8::ucwords()" + "UTF8::lcwords()" (don't use "implode()" if it's not needed)

### 5.4.23 (2019-09-27)

- improve performance from "UTF8::chr_to_decimal()" (now we use iconv if it's available)
- improve performance from "UTF8::html_entity_decode()" (code cleanup, remove dead code)

### 5.4.22 (2019-09-26)

- improve performance by replacing ```count($a) === 0``` with ```$a === []```
   -> so we don't need a function call to check if an array is empty

### 5.4.21 (2019-09-17)

- improve performance by not using return types for ```private``` methods
   -> the code is already checked via phpstan + psalm + phpstorm, ...
      so no need to check it every time at runtime at this point

### 5.4.20 (2019-09-16)
