Release 4.1 Status

Improve Image

The current release version is JTLS 4.1.14.0. This is the last official bug fix release for JTLS 4.1 and will continue to be supported by R&A by answering questions and providing minor bug fixes if needed until 1 January 2018.

If your organization is planning a JTLS 4.1 exercise after January of 2018, please contact us as soon as possible. Due to the extensive changes in JTLS-GO 5.0, we will consider keeping JTLS 4.1 active for a short time after the planned expiration date. Please continue to contact the Help Desk at jtlsdev@rolands.com with any questions or issues.

If you have an earlier version, you should strongly consider downloading and upgrading to the latest version. Several upgrades have been applied since the latest release.

Configuration Management

R&A has establish the following configuration management numbering system for JTLS. Each JTLS version consists of a four digit identifier, i.j.k.l, such as 4.1.3.0.

The digits have the following meaning:

Digit Explanation
1st Digit (i) This is the major version number. A change in the major version number indicates that the system concept of JTLS has undergone a significant change. When making a significant change, users should expect a longer than normal time to assimilate and fully understand the new capabilities and system structure of JTLS. A larger than normal database contgent changes should be expected. For example JTLS 3.0.0.0 was the version number when JTLS moved to the new web-based user interface.
2nd Digit (j) This is the main version number. A change in the main version number indicates that the JTLS has signficiant new model functionality that required new data. A change in the main version number means users must upgrade their database, an automatic procedure delivered with JTLS, and review these databases to insure that their scenario use the new functionality as desired and needed.
3rd Digit (k) This is the update version number. A change in the update digit indicates that JTLS is being released with "bug" fixes found by our test team and other users. It is possible that a few minor functional improvements have been added to the model, but absolutely no data changes were needed. Thus, the database structure for JTLS Version 3.4.1.0 is identical to the database structure for JTLS Version 3.4.0.0. Although each user must individually decide whether to implement an upgrade version, it should be noted that as a "bug" fix release, it represents what R&A believes is the most reliable released version of JTLS.
4th Digit (l) This is the interim version number. A change in the interim digit indicates that an unofficial release of JTLS is being used. If an individual user has a specific problem just prior to an important exercise, R&A may fix the issue and provide the fix on a quick reaction test cycle. The issues addressed in the interim release will be formalized and included in the next update release. Only the user requiring the quick fix receives notification of the release availability.
