The procedure for updating thirdparty on develop-9.0 and develop branches is slightly different due to thirdparty prebuilts on develop.

1. Push up a PR to this repo
2. If there is a related patch to another repos then push up a PR for those
3. Create a test branch on livecode with updated submodule ptrs. Ensure the branch is pushed upstream rather than to your clone.
4. If it was a CEF update then push up a branch to livecode-private again with updated submodule and kick off prebuilts on vulcan.
5. Create a PR with the title beginning with [[ NO MERGE ]] and review it ok to confirm it passes on travis and vulcan
6. Close PR from 5 and link to it in the other related PRs
7. Once all related PRs are reviewed merge thirdparty, update submodules in livecode and merge any related PRs

The same procedure applies to merge-ups from develop-9.0 because the thirdparty prebuilts must be rebuilt for the current head of the develop branch.

1. Push up a PR to this repo
2. If there is a related patch to another repos then push up a PR for those
3. Review and merge the PR for thirdparty but do not update submodule ptrs in livecode yet.
4. Create a test branch on livecode with updated submodule ptrs. Ensure the branch is pushed upstream rather than to your clone.
5. Push up a branch to livecode-private again with updated submodule and kick off prebuilts on vulcan.
6. Once prebuilts are built for the develop head of thirdparty create a PR using the livecode branch with the title beginning with [[ NO MERGE ]] and review it ok to confirm it passes on travis and vulcan
7. Close PR from 6 and link to it in the other related PRs
8. Once all related PRs are reviewed, update submodules in livecode and merge any related PRs
