FYI, the release process is changing in 2.18: github releases is now where pants is published, and 2.17 is the last release that publishes to PyPI.
For example, the assets on
https://github.com/pantsbuild/pants/releases/tag/release_2.19.0.dev0 are now how one gets that version of pants.
This all happens via the new "pants" launcher, and isn't supported with the old
./pants
script. For 2.19, you'll need to have a sufficiently new version of the launcher too (
SCIE_BOOT=update pants
).
