The final(?) iteration by the Freie Universität Berlin team on the #JezeroNorthernDelta was published last February.
Ovchinnikova et al: "Influence of the western inlet on the northern delta in Jezero crater: Topographic-compositional analysis and sediment transport modeling"
https://doi.org/10.1016/j.icarus.2025.116840A short summary also available at https://planetarygeomorphology.wordpress.com/2026/02/03/the-interaction-of-two-deltas-on-mars/

From last December: a new iteration on the #JezeroBrightRocks studies (previously https://mastodon.social/@sharponlooker/114042437186059919), this time with comparison to Earth's analogs. It still doesn't extend beyond sol 1000 (Neretva Vallis) so it doesn't cover the CRISM detections around Pico Turquino/Seattle Park (fig. 7)
Broz et al: "Alteration history of aluminum-rich rocks at Jezero crater"

From Dec 2025: dehydration experiment on a Bright Angel abrasion. They mention that it should be repeated with "wetter" minerals since the chosen BA formation has lower hydration than the delta front or #JezeroMarginUnit and more similar to the crater floor.
