# To update the port:
# The stable v8 version follows the chromium browser
# https://chromereleases.googleblog.com/search/label/Desktop%20Update
# search for "The stable channel has been updated to" XX.X.XXXX.XXX
#  -> https://github.com/chromium/chromium/blob/87.0.4280.60/DEPS
#     -> 'v8_revision': 'd2fef9fb0ac356d6cf6759f29e2b56ebea8bc58d'
# https://github.com/v8/v8/commit/d2fef9fb0ac356d6cf6759f29e2b56ebea8bc58d
#  -> Version  8.7.220.23
# then:
#  - make makesum
#  - update the various hashes (BUILD_HASH...), see below:
#    egrep "build.git|buildtools.git|clang.git|common.git|googletest.git|icu.git|zlib.git" ${WRKSRC}/DEPS
#  - make MAINTAINER_MODE=yes fetch (warning, it'll try to upload them on my account on freefall)
#  - make makesum (to update the various deps hashes)
#  - make clean ; make (and fix the patches if needed)
