  At the end of March 2015 the onboard software configuration of the AGILE
satellite was modified in order to disable the veto signal of the
anticoincidence shield for the minicalorimeter instrument. The motivation for
such a change was the understanding that the dead time induced by the
anticoincidence prevented the detection of a large fraction of Terrestrial
Gamma-Ray Flashes (TGFs). The configuration change was highly successful
resulting in an increase of one order of magnitude in TGF detection rate. As
expected, the largest fraction of the new events has short duration ($< 100
\mathrm {\mu s}$), and part of them has simultaneous association with lightning
sferics detected by the World Wide Lightning Location Network (WWLLN). The new
configuration provides the largest TGF detection rate surface density
(TGFs/$\mathrm{km^2}$/year) to date, opening prospects for improved correlation
studies with lightning and atmospheric parameters on short spatial and temporal
scales along the equatorial region.
