Prev	Chapter II. What’s new in Cassandra PV Archiver 3.x	Next

The Cassandra PV Archiver 3.1 adds a few new features and updates its dependencies to their respective newest versions. It is compatible with the Cassandra PV Archiver 3.0.x, meaning that it can operate on data stored by the Cassandra PV Archiver 3.0.x and the APIs supported by the Cassandra PV Archiver 3.0.x are fully supported.

The following features have been added in this release:

A web-service API for managing the server has been added. This API is described in detail in Appendix C, Administrative API.
The administrative user-interface now uses AJAX to load the list of channels asynchronously. This improves the performance when displaying a list containing a large number of channels.

There also are some bugfixes and minor improvements:

For each module containing Java code, a source JAR is generated in addition to the binary JAR.
A NullPointerException that could occur when updating a channel while concurrently moving or deleting it has been fixed.
The launcher script on Windows now works correctly when the path where the Cassandra PV Archiver is installed contains spaces.
All library dependencies have been updated to their newest versions.

2.1. Cassandra PV Archiver 3.1.1

Version 3.1.1 is a bugfix release that fixes an issue with displaying the channel state in the channel list.

Unfortunately, a regression was introduced shortly before the release of version 3.0.0. This regression caused the state of a channel not to be visible in the list view (but it would show on the details page for a channel). This problem is fixed in version 3.0.1 so that the state now is also visible in the list view (like it was in older versions).
