  There are several experimental indications of sterile neutrinos with a mass
in the 1 eV ballpark and many experiments are trying to clarify the situation.
During 6 years the DANSS experiment collected more than 6 million Inverse Beta
Decay (IBD) events and measured the background level during 4 reactor-off
periods. Data were collected at 3 distances (10.9 m, 11.9 m, and 12.9 m) from
the center of the core of a 3.1 GW$_{th}$ reactor with event rate up to 5
thousand per day. The detector position was changed frequently usually 2-3
times a week. Therefore many systematic uncertainties were canceled out in the
analysis. After collection of additional 0.7 million IBD events the
significance of the best-fit point in the 4$\nu$ case increased from
1.3$\sigma$ to 2.35$\sigma$. This is still not statistically significant and we
present the exclusion area that covers a very interesting range of the sterile
neutrino parameters up to $\sin^22\theta_{ee} < 0.004$ in the most sensitive
point. In particular DANSS excludes a large fraction of sterile neutrino
parameters preferred by the recent BEST results including the BEST best-fit
point. The IBD rate dependence on the fuel composition was measured. It agrees
with predictions of the Huber-Mueller model. During almost 6 years the reactor
power was measured with $\approx1.8\%$ accuracy in 2 days using the
anti-neutrino event rate normalized to the reactor power at the initial period.
