New licensing model

[Peter Knowles]

With effect from August 22 2018, a new model for new and renewing licences for Molpro has been adopted. Instead of having fixed versions, which were previously released about every 3 years (e.g. Molpro2012, Molpro2015, Molpro2018), all upgrades and improvements will be made available when ready to the licensees of version Molpro2018 (or later). This means that there will be no extra fee any more for upgrading to a new version. However, all licences will be time limited. In the long term, the licence fees per year will be similar as so far. The advantage for Molpro users is that they can immediately take advantage of the latest developments, while the advantage for the Molpro team is that only the latest version needs to be maintained.

All holders of licences purchased later than June 30, 2017 will automatically get a free licence for Molpro2018, which is valid for 4 years from the starting date of their previous licence for Molpro2015 (which remains valid as well). Discounts are available for upgrading older licences.

Molpro 2018 will be released soon. Holders of licences for Molpro2018 can already download and try a pre-release beta version. Any feeback regarding improvements of this version will be appreciated.

Molpro 2012 and older versions will no longer be supported. Important bug fixes will be applied when necessary to Molpro2015 until June 30, 2020.
