[MarkLogic Dev General] MarkLogic Server 4.2 Now Available on DMC

[Eric Bloch]

As many of you may have heard, MarkLogic Server 4.2 is now available for download at http://developer.marklogic.com .    This significant new release introduces new features in several important areas:

Agility and ease-of-use

 *   Information Studio - a browser-based tool and high-level APIs that simplify loading and transforming content for information applications.
 *   XSLT 2.0 - This widely-known and deployed programming language can now be used directly as part of MarkLogic applications.  As is the norm with MarkLogic, it is purpose-built from scratch for high-performance and seamlessly integrated with the rest of the server.
 *   Support for OS X as a development platform - woohoo as I type from my Mac!

Enterprise-grade robustness

 *   Replication Asynchronously replicate documents between two databases or directories.
 *   Database rollback Roll back a database to a specified point in time to recover immediately from a data-destroying event.
 *   Local-Disk Failover High availability in the face of server failure by automatic failover to a synchronous copy of the database.
 *   Compartment security An extension to MarkLogic's role-based security model to include compartments.
 *   Password policy plugin Set password policy at the system level with an administrator-defined password check function.

Industry-leading search and discovery

 *   Distinctive terms Determine the words/terms that best represent a document or a sequence of nodes.
 *   Proximity boost Boost the score of a search result based on the proximity of terms.

As with all feature releases, 4.2 includes a host of other significant enhancements as well.   Below I've also included a list of docs<http://developer.marklogic.com/docs> that are new or have significant additions in 4.2:

 *   Information Studio Developer's Guide
 *   Flexible Replication Guide
 *   Scripting Administrative Tasks Guide
 *   XQuery and XSLT Reference Guide
 *   Scalability, Availability, and Failover Guide (now includes local-disk failover)
 *   4.2 Release Notes - a summary of new features, upgrade compatibility information, and other information about this release.  (Yes, it's a good idea to rtfrn.)

We've also put up a couple new tutorials<http://developer.marklogic.com/learn/tutorials>:


 *   5-Minute Information Studio Walkthrough
 *   Learning to use Search Clustering

and a new sample application for Information Studio<http://developer.marklogic.com/blog/information-studio-intro-video> as well.

We'll be releasing a number of other 4.2-related materials available over the next few weeks as well.

Best,
Eric
