To reference or cite the objects present in the Software Heritage archive, permalinks based on SoftWare Heritage persistent IDentifiers (SWHIDs) must be used instead of copying and pasting the url from the address bar of the browser (as there is no guarantee the current URI scheme will remain the same over time).

Changes in snowfall 1.83 =========================== o sfIsRunning: new function giving a logical is sfInit() was called or not. Needed, as all other snowfall functions implicitely call sfInit() if it was not called. Changes in snowfall 1.82 =========================== o Internal refactorings. Changes in snowfall 1.81 =========================== o Change in sfInit() MPI startup so sfCluster can run with snow > 0.3 now. o sfExport now also works in sequential mode (writing to global environment). This prevented sequential execution in some cases. Changes in snowfall 1.80 =========================== o snowfall passes packages checks of R 2.10.1 without warning or error. Internal state is now only saved in the namespace itself (thanks to Uwe Ligges for the tipp). o sfExport can now also export objects in a specific namespace (argument 'namespace') o sfExport: behavior in error case manageable (stopOnError) o sfExport: smaller bugfixes. o sfRemoveAll can now also remove hidden names (argument 'hidden') o sfRemoveAll is more robust now (some minor bugfixes, more checks) o sfRemoveAll bugfix for multiple removals (thanks to Greggory Jefferis) o Bugfix on exception list on sfExportAll o Refactorings in sfTest() o snowfall now has a NEWS doc ;) o No warning on Mac OS because of default Mac-R command line arg 'gui' (thanks to Michael Siegel).
