# announced NIKON depreciation is a no-go ## first info ``` From: Roman Lebedev <lebedev...@gmail.com> To: darktable-user <darktable-u...@lists.darktable.org>, darktable <darktable-dev@lists.darktable.org> Subject: [darktable-dev] PSA: ATTENTION NIKON OWNERS !!! Date: Fri, 7 Oct 2016 16:00:48 +0300 [...] or else your camera will not be supported in next darktable release! [...] ``` **shocking** ## why using open-source software because it's sustainable. maybe not perfect. but good enough 1. First question for using a Digital Camera: is it in dcraw? 2. Second: always use RAW. Nothing else. D70 raws from 2005? __NO Problem__. The camera has long gone. ## which software * [dcraw](http://www.cybercom.net/~dcoffin/dcraw/) the reference * [ufraw](http://ufraw.sourceforge.net/) always with me, even on 7year old netbook * [darktable](http://darktable.org/) for work. and fun. and ... (99% used) # Confusion ## who is informed * darktable-user * darktable-dev ## who is not informed (maybe the other 98%) * users of any distribution where some more-or-less actual version of darktable is provided ## what will happen if a dumb user updates a +0.0.1 version? * backward incompatible changes will be introduced. (for darktable normal and accepted behaviour) * loosing silently old pictures. ymmd. * no easy rollback. depends on the time when you realize the breakage. ## and what happended to a git user * #@!^^# in gui: * failed to read camera white balance information from '2005...nef' 'working..' (stale) * showing the skull icon after reentering lighttable * only seen because started on command line: ``` [rawspeed] (20050507-15004070-NIKON_D70.nef) Camera not supported (explicit). Sorry. [temperature] failed to read camera white balance information from `20050507-15004070-NIKON_D70.nef'!

[temperature] failed to read camera white balance information from `20050507-15004070-NIKON_D70.nef'! allocation failed??? ``` # Conclusion i'm bored and disappointed. sorry. # whats next ## taking a look at [semantic versioning](http://semver.org/) whatever API means. (supported cameras, modules, xmp, database(es)) where database is more internal, could be regenerated out of xmp's. ``` Given a version number MAJOR.MINOR.PATCH, increment the: 1. MAJOR version when you make incompatible API changes, 2. MINOR version when you add functionality in a backwards-compatible manner, and 3. PATCH version when you make backwards-compatible bug fixes. ``` point 7. for marking something deprecated ... and then wait an amount of time i.e. one or two releases. point 8. for introducing incompatible changes my feeling: always all released versions shoud have been major? j/k ## giving a valuable feedback to the user * version has to introduce a deprecation message when database of user shows findings (for ex: sql-ing for known cameras and give a big bummer on screen and log to provide raw files) * keep non-optimal whitebalance stuff. better than to nuke. maybe mark previews.
