Well it looks like this planet HD 150706b is not the same as the previous claim which gave an orbital period of 264 days.

There have also been updates to HD 89307b and HD 154345b. Seems the latter is not such a good Jupiter-analogue as previously suggested: the eccentricity has been updated to 0.260.15 from the original value of 0.044 0.046.

The SOPHIE search for northern extrasolar planets. V. Follow-up of ELODIE candidates: Jupiter-analogues around Sun-like stars

HD 24040 shows a radial velocity drift that may indicate a companion in an even longer period orbit. This was responsible for the earlier estimations of a longer orbit and higher mass for HD 24040b. Inner planets with m sin i > 0.62 MJ are excluded.

HD 150706b may be responsible for clearing out the inner hole in the system's dust disc.

Aside from HD 89307b, the orbital eccentricities are non-significant (wide error bars).
