This plugin update does not contain significant changes, except for removing the maximum IntelliJ version requirement - that is, by default, we hope that new versions of Jetbrains Python module do not break this plugin.
That is, if the IDE stays compatible, (which has been the case since version 2017.3), then no action on the part of the maintainer will be required, instead of the previous situation where the plugin must be updated for the maximum version requirement.
This plugin is also published on the official JetBrains plugin repository: Pysynthetic plugin. (The last version may not be available on the official repository immediately.)
