Develop setting names in LR3 and LR4,5

Question

Hello
I'm trying to work with develop setting.
to get current setting I use
photo:getDevelopSettings()
and for set settings I use
LrApplication.addDevelopPresetForPlugin
photo:applyDevelopPreset
The problem is. If in LR3 (bot Mac and Win) I modify a settings with keyname "Contrast" then it is correctly applied this setting to LR's develop seting "Contrast" and everuthing works as it should.
But in LR 4 and LR 5 it just create an inner plug-in seting with name "Contrast" what has not any affect on LR's setting "Contrast"
I looked throw many pages of this forum and dint meet any mention about same problem. But I met what sometimes in some samples the develop settings are named as i.e "Exposure2012" instead of "Exposure".  There is a some special rules how to use setting's keys to access to standard LR develop settings independly of LR version?

The LR 5 SDK API Reference does mention the process version 2012 settings:
However, as mentioned above, the documentation isn't well-maintained, so you're always better off double-checking it by dumping out the results of getDevelopSettings().  E.g. in LR, take a sample photo, set all the develop settings to non-default values, and then in a script invoke Debug.lognpp(photo:getDevelopSettings())  (using the Debug module from my debugging toolkit for Lightroom).
probably the simplest way is just check some global environment variable with LR version number and use keynames accordingly this value.
Agreed.  You can get the version via LrApplication.versionTable().
