What's new in OpenMRS 1.8

Release date: 20 June 2011

We asked you for suggestions on how to improve the performance of OpenMRS in real world implementations.  After collecting a lot of feedback, we're proud to announce version 1.8, which is less focused on new functionality, and more focused on making existing functionality faster and more efficient. More importantly, we used this release cycle to integrate consistent mechanisms to evaluate the performance of the core application. From now on, we will be able to make sure that new versions of the code get faster, not slower, through continuous benchmarking.

It is highly recommended to upgrade all of your modules to their latest versions to maximize the benefits this release has to offer. You may also visit Performance Tuning for information on how best to tune your installation of OpenMRS for best performance.

Performance improvements

  • The Patient Dashboard and a number of other pages simply load faster.
  • Search results are returned in a shorter time (e.g., when searching for patients, encounters, concepts, etc.).
  • The cohort builder has been sped up.
  • The data exports feature has been improved to consume less memory and attain better speed.
  • More performance-focused work has been done in modules that are commonly used across most implementations. Feel free to browse the OpenMRS Module Repository to check for any new versions and upgrade.

  • Features from the Program Location Module has been incorporated into the core OpenMRS application.
  • Improved workflow when adding a new program and state.
  • Improve workflow when ending a program with a terminal state.

Icon

As of described in Unsupported Releases (EOL), OpenMRS can only support up to three released versions at a time (the current release and then two versions back). With the release of OpenMRS 1.8.0, support is no longer provided by the core Development Team for OpenMRS 1.5.x and earlier. This announcement also serves as advance notice that support will end for OpenMRS 1.6.x, concurrent with the release of OpenMRS 1.9.
