Welcome to 4D v15. This manual describes all the functions and implementations added in this new major release of 4D.

4D v15 represents a crucial step in the process of integrating 4D applications with new technologies, both hardware and software, while providing many features expected by the 4D developer community:

• New "Object" type fields,
• Multiple optimizations (searching via the SQL engine and sorted arrays, new ServerNet network layer, elevated levels of network security, extended support for Unicode, etc.)
• New features making 4D code independent from local settings (Unicode mode and international mode for methods),
• Opening to new technologies: 4D Mobile for connection to Wakanda applications, LDAP for connection to company directories, new 4D tags as alternatives to XSLT technology, which is being abandoned,
• Addition of many new commands and functions for managing forms and their objects, such as list boxes, to assist with designing modern and dynamic interfaces,
• New 4D Write Pro object for integrated editing and word processing,
• Addition of features for monitoring and introspection of code and queries,
• New OS X 64-bit versions: 4D v15 delivers not only the OS X 64-bit version of 4D Server (preview), but also of 4D Internet Commands, 4D Pack, 4D For OCI, 4D ODBC Pro and 4D ODBC Driver, allowing you to build a complete environment on Apple's most powerful machines (note however that 4D Server 64-bit for OS X being provided as a preview release, it is not recommended to deploy it in a production environment). 

Note: If you are a member of 4D's continuous delivery (R-release) program, you have already had the opportunity to perform several progressive updates of your 4D applications and this version is simply another new release. For example, if you are using version v14 R5, you already have all the new features stamped "v14 Rx" that are included in this manual and which were covered in previous R-version upgrade manuals. In this case, you can just read the 4D v15 - Upgrade (R-release edition) manual.
