UPCOMING
The upcoming Starfall Cluster book (Glimmerdrift Reaches) has many pages each on: 2411 Starfall, 2410 Idam Lee, 2511 569-519 aka Hidamae, 2513 812-848, 2514 Arnigi, 2611 Lunarise, 2612 Ur, 2613 743-128, 2712 Dhuku, 2713 Arka Videa. It also includes standard library data for 2110 Darvin's Hope, 2209 Saga's End, 2210 519-036, 2211 Eda, 2212 Shuriken, 2215 Cixntha, 2309 User-Friendly, 2407 Ur, 2415 Didan, 2810 Kiru Dis, 2815 Midrift, 2910 Waypoint. A few of these snuck out early via descriptions in the EAs.
OTHERWHEN
GURPS Traveller Planetary Survey 3 describes Granicus (0520 Glimmerdrift) in some depth, along with background for the Federation of Heron. It is set in the year 1120 rather than 993 but is compatible allowing for the passage of time.
Quite a few Gateway worlds got some description in issue 4 of the Megatraveller's Journal. This covers the same setting about a hundred years later. It is compatible with G993, with appropriate differences for the time gap. The list:
1220 Gateway (Galian Federation)
0921 Salur (Galian Federation)
0527 Amberinth (Galian Federation)
0528 Tharver (Galian Federation)
1319 Galvaren (Galian Federation)
1725 Trindel (Trindel Confederacy)
1527 Taravesh (Trindel Confederacy)

1530 Gasper Belt (Viyard Concourse)
1736 Catanin (Viyard Concourse)

GONE AND BURIED
Back in the depths of time, Judges' Guild published various material for the GtD area. That has been "decanonised". GtD replaces it and does not match it.
