Release notes

Last update: May 2017

These release notes concern maintenance operations on SoDa on MINES ParisTech servers, i.e. impacts both www.soda-is.com and www.soda-pro.com for a few hours. Same maintenance operations are then carried out on the mirror website afterwards (pro.soda-is.com and www.tsv.soda-pro.com). Users who purchased an annual subscription to access the HelioClim-3 database are informed by email a few days before, and also as soon as the SoDa Service is back to normal.
