We present an update to seven stars with long-period planets or planetarycandidates using new and archival radial velocities from Keck-HIRES andliterature velocities from other telescopes. Our updated analysis betterconstrains orbital parameters for these planets, four of which are knownmulti-planet systems. HD 24040 b and HD 183263 c are super-Jupiters withcircular orbits and periods longer than 8 yr. We present a previously unseenlinear trend in the residuals of HD 66428 indicative on an additional planetarycompanion. We confirm that GJ 849 is a multi-planet system and find a goodorbital solution for the c component: it is a $1 M_{\rm Jup}$ planet in a 15 yrorbit (the longest known for a planet orbiting an M dwarf). We update the HD74156 double-planet system. We also announce the detection of HD 145934 b, a $2M_{\rm Jup}$ planet in a 7.5 yr orbit around a giant star. Two of our stars, HD187123 and HD 217107, at present host the only known examples of systemscomprising a hot Jupiter and a planet with a well constrained period $> 5$ yr,and with no evidence of giant planets in between. Our enlargement andimprovement of long-period planet parameters will aid future analysis oforigins, diversity, and evolution of planetary systems.
