+# Documenso v1.6.1: Internationalization, Enhanced OIDC, and More
+
+We're excited to announce the release of Documenso v1.6.1, which brings several improvements to enhance your document signing experience. Here are the key updates:
+
+## 🌟 Key Features
+
+### New Initials Field Type
+
+We've added a new field type for initials, giving you more options for document customization. This feature allows signers to quickly initial documents, adding an extra layer of verification to your signing process.
+
+### Internationalization Support
+
+We've taken a big step towards making Documenso accessible to a global audience by adding i18n (internationalization) support for our marketing pages and adding translations to support multiple languages.
+
+While this is just a small step towards a fully multilingual Documenso, it's a significant step towards making our platform more accessible to a global audience.
+
+Using our new knowledge and findings from the marketing implementation, we aim to tackle our web application in the near future for a fully global Documenso.

+
+- Now supports OIDC-only signup

+- The OIDC sign-in button text is now configurable

+
+  - Fixed display issues with field names/labels in dark mode
+  - Improved truncation of titles to prevent UI breaks
+
+- **User Experience**:
+
+  - The signup option is now shown only to users without existing accounts
+  - Fixed issues with radio and checkbox fields having empty values
