Say, I do run BWS in "Without Update" mode and use its BWP option, and also say there exist, for the sake of example, 1PP v5.2.4.
If my local ini file says (within the same example) that BWS should go exactly to http:/ /www.shsforums.net/files/download/1006-1ppv410/ and grab there exactly 1ppv4.1.0-rel.7z file, is there any mechanic in force that will made BWS to download 5.2.4 instead of 4.1.0?
It will download 1PP v5.2.4 as soon as it will be updated to 5.2.4. That's the whole purpose of stable download links: always download most recent version of the mod. The 'Version' key is only text, its's used only to display mod version and it needs to be updated manually for each new mod version.
Ahha, perhaps I finally understand. You're telling about stable download links like that "/master" on GitHub, where never version replace older version under the same link as soon as never version released? That's something happening on the host side and BWS can not be held responsible for that, of course, and given update mention in BWS readme I figured it describes something happening on BWS side, like, if BWS might download new version of a mod even if older version mentioned in that mod's ini file is still perfectly available.
Anyway, it's too late for discussion about BWS features.
How so? True, I am definitely not the one even distantly capable of implementing that feature, but may be there is or there will be someone both capable and interested. BWS saw a good share of maintainers suddenly happening when all seemed to be lost
