Version 1.4.0 changes
Internationalization (i18n)
The application has been completely internationalized to allow the support of multiples languages. The app currently ships with English only, but new languages can be added relatively easily. See contextual documentation for details.
Webcam support
The HTTP Image data source has been added, which is capable of capturing snapshot images from any image source available on the internet. Users can add their own code to allow single-clicking into live feeds if supported by the source.
Interval logging
Mango now supports interval logging. This concept separates the gathering of data from its storage in the database. Now, data sources can gather samples at a much greater rate than they are stored, while the storage of data can be instantaneous or statistical (average, minimum, or maximum over the interval).
View sharing
Graphical views can now be shared with other users. Access rights can be assigned to limit view permissions similar to anonymous view access.
Data source copying
Data sources may now be copied. This allows complex point configurations to be easily recreated in a new data source. User permissions and point event detectors are also duplicated.
Graphical chart upgrades
Graphical charts can now render binary and multistate data in addition to numerical data. Lines are rendered in a square-wave fashion and are quantized over the scale any numerical data that is also shown.
Online documentation
Online documentation is now shipped with the Mango distribution, rather than being served from central Mango servers. This allows developers to modify documentation and document their own features.
Performance enhancements
Startup time for data sources and data points that have large histories have been significantly improved.
Other
Various improvements and minor bug fixes.
