Branches

• Master - stable but less actively developed branch of emoncms. New features will be far and few between but testing will be more extensive., _(*3)

• Extended - An extended feature set branch of emoncms for advanced users. This branch may be less stable than the master branch , pull requests are merged with light review for quick development., _(*4)

• BufferedWrite - A low write version of emoncms designed for running on SD cards, this is a cut down version of emoncms supporting only the phpfina and phptimeseries feed engines (no in built feed averaging or histograms) and a reduced input processor set. Data is written to disk at spaced out intervals allowing datapoints to buffer and be written to disk in larger blocks., _(*5)
