- Usage tracking! We can now track and upload (anonymously) use counts at the plugin level, along with information about the environment of use (country, java version, language, operating system, time zone). Although we are taking care not to expose any user data with these statistics, this feature can be disabled via a new Edit › Options › Privacy… setting. Expect great things coming to the usage page! (note: “great things” = statistics graphs)
- Groovy scripting! The Groovy scripting language is one of the most popular available for the JVM. Hence, ImageJ now has built-in support for Groovy as a scripting option.
- All images, whether opened with the SCIFIO option enabled or not, should now be automatically populated in
@Datasetannotations in scripts and plugins. This will make parameterized scripting much more consistent and useful. See the scripting guide for more information and tutorials.
- More plugin types! Continuing our dedication to making ImageJ2 a flexible and extensible platform, we converted some lower level utilities to pluggable services: type conversion and preference storage. This won’t mean much to users right now, but it gives developers new ways to tap in to the functionality of ImageJ, and plays a key role in extensions like our upcoming MATLAB scripting language!
- We resolved a significant memory leak due to images not being closed properly. This was also causing naming errors (e.g., the second time you opened “Data” it would display a title “Data-1” even after closing the first image) and other terrible gotchas. As a consequence, the linkage between ImageJ2 and ImageJ 1.x data structures maintained by the legacy layer is now more robust.
- We fixed several bugs in SCIFIO; e.g., ImageJ slice labels should now be preserved after saving and reopening in TIFF format.
- Quite a few other small bug-fixes; for example, the languages shown in the
Languagesmenu of the Script Editor now appear in a consistent and alphabetical order.
