NADA 5.0

This is a substantial upgrade to NADA which brings a host of new features as well as upgrades which address compatibility issues with recent updates to PHP.

Why upgrade?

  • Previous versions of NADA were built to be compatible with the latest versions of PHP (5.3 up to 5.6) available at the time.
  • Support for PHP 5 was discontinued in December 2018.
  • The maintainers of PHP encourage all users of PHP to upgrade to PHP 7+
  • NADA 5.0 has been rewritten to run on PHP 7+

It is strongly recommended that all users of NADA upgrade to the latest version of PHP. Upgrading PHP to version 7 will necessitate that you also upgrade your NADA to 5.0.

What's new in NADA 5.0?

  • Adobe Flash uploads are now replace with HTML 5 uploads. This fixes changes made in most modern browsers which remove default support for Flash.
  • PHP no longer supports MySQL drivers. Support for MySQL has been replaced with the MySQLi and MySQL PDO drivers. NADA 5 supports these new drivers.
  • NADA now uses Bootstrap 4. This means that NADA uses a responsive design that works well on all devices, including mobile devices.
  • The framework underlying NADA now runs on the latest version of CodeIgniter.

Exciting new functionality in NADA 5.0

  • Search has been updated to allow indexing of all the metadata fields.
  • The templating system has been updated to accommodate all DDI 2.5 fields. The previous version of NADA only supported a subset of the DDI Codebook.
  • A more powerful API is available which allows searching, browsing and managing the catalog via API.

NADA 4.4

NADA 4.4 is the latest official release and requires at least PHP 5.3 or above to run. We strongly recommend that you use PHP 5.5 or later with the MySQL 5.x database.

The current release fixes issues related to PHP 5.6 and file uploads for resources. In newer versions of Chrome and other browsers, Flash is disabled by default which causes the file upload features on the NADA site adminstration pages to fail. This release fix replaces Flash with HTML5.
