 [GNU gettext utilities](https://www.gnu.org/software/gettext) for Go. 
 
-Version: [v1.0.1](https://github.com/leonelquinteros/gotext/releases/tag/v1.0.1)
+Version: [v1.1.0](https://github.com/leonelquinteros/gotext/releases/tag/v1.1.0)
 
 
 # Features
 
 - Implements GNU gettext support in native Go.
-- Complete support for [PO files](https://www.gnu.org/software/gettext/manual/html_node/PO-Files.html).
-- Support for [pluralization rules](https://www.gnu.org/software/gettext/manual/html_node/Plural-forms.html).
-- Support for [message context](https://www.gnu.org/software/gettext/manual/html_node/Contexts.html).
-- Support for variables inside translation strings using Go's [fmt package syntax](https://golang.org/pkg/fmt/).
+- Complete support for [PO files](https://www.gnu.org/software/gettext/manual/html_node/PO-Files.html) including:
+  - Support for multiline strings and headers.
+  - Support for variables inside translation strings using Go's [fmt syntax](https://golang.org/pkg/fmt/).
+  - Support for [pluralization rules](https://www.gnu.org/software/gettext/manual/html_node/Translating-plural-forms.html).
+  - Support for [message contexts](https://www.gnu.org/software/gettext/manual/html_node/Contexts.html).
 - Thread-safe: This package is safe for concurrent use across multiple goroutines. 
 - It works with UTF-8 encoding as it's the default for Go language.
 - Unit tests available.

 ## Use plural forms of translations
 
 PO format supports defining one or more plural forms for the same translation.
+Relying on the PO file headers, a Plural-Forms formula can be set on the translation file
+as defined in (https://www.gnu.org/savannah-checkouts/gnu/gettext/manual/html_node/Plural-forms.html)
+
+Plural formulas are parsed and evaluated using [Anko](https://github.com/mattn/anko)
