Release Notes for ModeShape 4.0.0.Alpha2

This document outlines the changes that were made in ModeShape 4.0.0.Alpha2. We hope you enjoy it!

What's new

4.0.0.Alpha2 provides a fast, elastic, distributed hierarchical database that clients work with via the standard JCR 2.0 (JSR-283) API. ModeShape 4 is a major upgrade over 3.x and offers significant improvements in clustering, performance, query, and events. All JCR 2.0 features are supported, and ModeShape 4 has complete integration with Wildfly 8, allowing deployed applications to simply lookup and use repositories managed by ModeShape's service.

As of 4.0.0.Alpha1, ModeShape is licensed under the Apache Software License, 2.0.

This is the second alpha release of the 4.0 stream, and it includes several fixes and new features. The previous alpha release introduced a new query engine that allows clients to explicitly define the indexes used in the query system, and this second alpha release brings minor changes to the Service Provider Interface (SPI) for query providers. Version 4.0.0.Alpha2 does introduce a programmatic API and configuration modifications for defining indexes, although no complete query providers are included (see next release).

Additionally, this release has support for the JCR event journal feature, allowing applications to poll for changes that occurred during time ranges. This is a useful alternative to listeners that may be expensive or time-consuming.

What to test

Since this is an alpha release, not all features targeted to 4.0 are complete, and there are likely bugs with some of the newer features. Therefore, please do not put 4.0.0.Alpha2 into production.

However, we would like to get as much feedback as possible, so we do ask that our community do limited testing with 4.0.0.Alpha2 to help us identify problems. Specifically, we ask that you test the following areas:
