We always loved its simplicity, and while it looks pretty +oldschool right now there are still many shops happily using it in production. + + + +Compatibility +------------- + +We fully support the BPaddon configuration language and will continue to do so. +It's also perfectly valid to run both products in parallel based on the very same +config files. New features are (mostly) added in a compatible way. + +Configuration titles and descriptions, properties related to state types or +permissions are examples for new features that didn't formerly exist. They are +stored as commented metadata in the file header and therefore invisible to the +old AddOn. + +The only way to break compatibility is to use newly introduced operators like +`NOT`. Once you do so, the old AddOn will no longer be able to parse your +configuration. + + + +Lot's of changes went on and are still going on under the hood. We have more +features and new language constructs. We separated the config reader from the +state fetcher in our code base. This will allow us to eventually support config +backends like SQL databases or the Icinga 2 DSL. + +This would make it easier to distribute configuration in large environments. + +Improvements +------------ + +Major focus has been put on execution speed. So while the Web integration shows +much more details at once and is able to display huge unfolded trees, it should +still render and refresh faster. Same goes for the Check Plugin. + +Behaviour for all operators is now strictly specified and Unit-tested. You still +can manually edit your configuration files. But much better, you also delegate +this to your co-workers, as Business Process definitions can now be built directly +in the GUI. |
