Vladmodels Zhenya Y114 Katya Y117 15 Upd < FAST – EDITION >

I need to figure out what the user is looking for. They might want an update log, a changelog, or a description of changes made in version 1.5 of these models. Since there's a specific model numbers like Y114 and Y117, maybe they are different versions or variations. The user could be a developer or someone familiar with version control, needing documentation.
