Adopt AGPLv3 with a narrow Energyplan combination permission and expose source access. New Energyplan workers use separate private-household terms; commercial use and distribution require a Sourceful license. Earlier grants remain unchanged.
Adopt AGPLv3 with a narrow Energyplan combination permission and expose source access. Commercial use of the AGPL-covered code remains allowed under its source-sharing terms. New Energyplan workers allow unmodified use with FTW only for a person's own private household. Free, noncommercial redistribution with FTW is allowed only for that household use, with the binary license and third-party notices. Other use or distribution requires a separate written Sourceful license, including commercial use, resale, paid installation/support and hosted or managed operation for others. Earlier grants remain unchanged.

Commercial installations must arrange Energyplan rights or omit the restricted worker before upgrading, including through automatic updates.

<p>For a modified distribution, its distributor must supply the matching
source, build files and any required installation information. The upstream
repository alone does not supply unpublished changes.</p>
