MantaRay 1.4 is now available. A new persistency mechanism was implemented in this release so that recovery of persistent files is now faster and more stable. In addition, the new persistency takes less disk space and when possible it reduces the size of the persistent file. An infrastructure was created for different persistency implementations other then file persistency.
Documentation was modified in the release as well - a new FAQ document was added to the documentation package and the "User Guide" and "Getting Started" documents were modified according to your input."
