  Previously we proposed a novel method to inspect the isotropy of the
properties of gamma-ray bursts (GRBs) such as their duration, fluences and peak
fluxes at various energy bands and different time scales, complementary to
existing studies of spatial distribution of GRBs by other authors. The method
was then applied on the Fermi GBM Burst Catalog containing 1591 GRBs and except
one particular direction where we noticed some hints of violation from
statistical isotropy, the rest of the data showed consistency with isotropy. In
this work we apply our method with some minor modifications to the updated
Fermi/GBM data sample containing 2266 GRBs, thus $\sim 40$ % larger. We also
test two other major GRB catalogs, the BATSE Current GRB Catalog of the CGRO
satellite containing $\sim 2000$ bursts and the Swift/BAT Gamma-Ray Burst
Catalog containing $\sim 1200$ bursts. The new results using the updated data
are consistent with our previous findings and no statistically significant
anisotropic feature in the observed properties of these samples of all GRBs is
found.
