Notes

ebarretto

Marking emscripten ignored as openjpeg2 code is only for test/example.

ccdm94

it seems like commit c58df149900 (for version 2.3.1) is very similar to commit 2d24b6000d (for version 2.1.1). This second commit is also the fix for CVE-2015-1239, which means these issues are both solved by, very similar commits, however, the changes seem to be applied to

cccdm94

different functions in each commit.
