Update to JMARS 3.1

JMARS users,

There's a brand new version of JMARS available for download from jmars.asu.edu, or for update from an existing JMARS installation.

Depending on how often you selected to check for updates when you installed JMARS, you might get a notification of a new version the next time you start the application. If you're ready to update, just give your approval and in a few minutes you'll be up and running with the latest and greatest we have to offer. If you're halfway through your presentation for LPSC and are worried that something might go wrong updating to a new version of JMARS, then feel free to wait until a later date. Just hit exit when the installer software offers to upgrade you to the latest version, and you can continue with the same version you currently have. If your installer doesn't automatically prompt you to update, you can manually initiate an update via the Help->Check for Updates menu within the JMARS application.

Some of the cache formats have changed between JMARS 3.0 and JMARS 3.1. We recommend clearing your JMARS cache if you encounter any issues, particularly with stamp images that have been previously rendered. You can clean your cache via the Help->Manage Cache menu item from within JMARS.

Speaking of LPSC, if you are using JMARS as part of a poster, presentation, or paper, we always appreciate having JMARS cited or acknowledged appropriately. On top of giving us a warm fuzzy feeling that our efforts are proving useful to the scientific community, it also helps to demonstrate to the Mars Program that their investment in the JMARS team is valuable and worthwhile. In addition, if you have an upcoming poster, presentation, or paper that made use of JMARS, and you'd like to bring it to the attention of the rest of the JMARS community, send us an e-mail and we'll include it on our website.

Whether or not you're using JMARS as part of presentations or publications, if you'll be at this year's LPSC, be sure to stop by the JMARS booth for an in person demonstration of the features included in this latest update, or for help doing any of the cool things you've seen or heard other people do with JMARS in the past. We'll also be happy to listen to new feature requests, suggestions or difficulties you've encountered with any aspect of JMARS.

If you previously read my announcement of the JMARS Beta at the end of January, much of the rest of this e-mail will look pretty familiar. All of the functionality from the Beta is now included in the production version of JMARS, along with a decent number of fixes that were applied throughout the course of the Beta. Thanks to everyone to downloaded and tested the Beta for us - your feedback was useful and greatly appreciated! We will continue to make updates to the JMARS Beta as we implement new functionality, so feel free to keep both versions installed if you so desire.

What new in JMARS 3.1?

Java version

We've updated the version of Java7 that we bundle with JMARS to include the latest fixes that are available. Don't worry - the Java that we include with JMARS is only used for JMARS, which means that it won't conflict with the version of Java you have installed on your system for other applications, and it won't create any additional requests to update Java on your system.

Installer version

Similar to the above explanation, we've updated our installer code to the latest version that's available.

General Changes

  • JMARS now runs with US Localization, regardless of the user's system preferences. This is a workaround to prevent issues that have occurred when coordinates and numeric values use different delimeters in different environments.

    • Shortcuts for the above all use the Ctrl key as their modifier (ctrl-x, ctrl-c, ctrl-v, ctrl-a)
