X product lead and Solana advisor Nikita Bier posted that X has officially launched one of its major updates: Custom Timelines. This feature allows users to pin specific topics to the homepage tab bar, currently supporting over 75 topics. Powered by Grok, the system dynamically generates each timeline based on user interests by combining deep understanding of each post with algorithmic recommendations, performing especially well on topics where users already have interaction preferences. Premium subscribers on iOS can now get early access, and the Android version will be rolling out soon. https://www.(wublock123.com)/news/news-59930
