Hi All,
FYI,
Earlier in this thread, we have now posted the Mapping of Sigil Version to Plugin Launcher Version information for all 0.8.X and later releases. We have also added information on specific plugin related changes for each of the Sigil-0.9.X pre-releases and releases.
The launcher_version always returns a simple integer representing the date YYYYMMDD when the final change to the launcher code was made for the upcoming release.
If your plugin requires a specific version of Sigil, you should be able to use this information to determine your minimum supported Sigil version (at least in the Sigil-0.9.X series).
See this post for more information:
