Announcing Our Inaugural Issue
With this, the first issue of GMG's quarterly newsletter, we hope to open new avenues of communication with our users. Every quarter we will be sending you news of product development, new releases, bug reports and fixes, upcoming events, articles on how to use MESA features to the best advantage, technical information on such topics as geophysical analysis tools, licensing, operating systems, etc. We also hope that you, our users, will see the newsletter as an opportunity to provide feedback and input back to us. We hope you enjoy this first edition and will reply with comments, suggestions and input on GMG products by emailing us at GMG Support. |

MESA 12.2 - Available Now!
We have added several new features including a tool for repositioning a source's live receiver patch based on the amount and direction a source gets moved. We also added the ability to calculate CMP fold from a flat horizon if you have significant elevation changes in your project area. For our marine users, we added a feature to create sailing configurations in which the streamers are 'splayed' behind the source boat. 
Read the release notes.MESA 12 is compatible with Windows 7, and has separate versions available for running on either 32-bit or 64-bit operating systems. If you would like to download MESA 12.2, you may send your request via e-mail to Sharon Day. Please note that if you are already using MESA 12 (and regardless of whether you switch between the 32-bit and 64-bit versions), you will not need to update your security key to use this latest software point release. Questions? Please contact GMG Support. |

Dave's Tips
Dave Cunningham, Manager of GMG SoftwareA new feature in MESA 12.2 is the addition of a "template compensation" tool on the source editing toolbar. This feature is used to modify the location of the shooting template after source points are moved.  The image to the left shows a source location(highlighted in green) shooting into an 8 line by 32 receiver template (highlighted in red). The automatic template centering routine was used to assign the template location. The black rectangle outlines the area of midpoint coverage for these source-receiver pairs. Read the full article.

Technical Update: FlexLM Upgrade
If you use FlexLM for your licensing of MESA, there is a critical update for MESA 12.2. If you use Safenet/Sentinel dongles exclusively this does not apply to you.
MESA uses Flexera's FlexLM Publisher software libraries that are built into MESA for its licensing. These libraries give GMG tremendous flexibility if fulfilling licenses and give our clients a well tested defacto industry standard licensing platform so that they can share licenses and monitor license usage very easily. Starting with Version 12.2 of MESA, we are upgrading the FlexLM software libraries we use to version 11.8 and this will require that our FlexLM users upgrade their vendor licensing daemon (gmglicd.exe on Windows or gmglicd on Linux) to a version built using FlexLM's version 11.8 libraries. Otherwise MESA 12.2 and higher will not work. There is no need to upgrade existing licenses but only to update the gmglid program and restart the license server.
The reason this is being done is for two reasons. Because of an explosion in the number of devices connected to the internet (computers, laptops, iPads and tablets, smart-phones, netbooks, network attached storage, appliances, game consoles) the internet is experiencing address space exhaustion. There are clever ways of getting around this such as Network Address Translation (NATS), etc. but this has lead to the entities that provide IP addresses to no longer issue standard IP addresses such as 127.0.0.1. Instead a new format for internet addresses called IPv6 is starting to ramp up and will be a necessity as the IPv4 address space is exhausted. In Windows Vista and Windows 7, IPv6 networking is built into to run in parallel with the IPv4. Our new vendor licensing daemon is designed to run with IPv6 and IPv4 so FlexLM license usage is future proofed with MESA 12.2 and higher.
The second reason is that Flexera enabled backwards compatibility with versions before 11.6. This backward compatibility was broken and hackers are able to exploit this and bypass all of the advances in cryptography incorporated into later versions of FlexLM. Hackers targeted MESA with these attacks. By moving to a later version we make piracy of our software extremely difficult and ensure the integrity of MESA.
