<p>Topcrash reports [1] now have several signatures identified as
"new", dated 2019, in the "First Appearance" column. But this is
the result of ntdll.dll being added in prefix list (bug 1515487),
not because we have more/new crashes. And this change has been
backfilled to crashes one month old and newer, so recent crash
reports are also categorized with a new signature.</p>
<p>For example, instead of shutdownhang | ntdll.dll@0x21f5d (bug
1509519) we now have one or more signatures like shutdownhang |
ntdll.dll | arena_t::GetNonFullBinRun | nsThread::Shutdown |
nsThreadManager::Shutdown</p>
<p>In the coming weeks, will need to put the new crash signatures in
the bug reports.<br>
