• FEATURE Added play-by-play badges flagging fouls and substitutions. proposed by @gulon
• CHANGE Made the Manual visible to search engine crawlers, plus a few other SEO improvements
• FEATURE Added training selection to the player profile — proposed by @Ezze8787
• FIX Fixed an issue with academy player avatars — reported by @grobarbrate and myself
