* changes necessary for concurrent thread safe global deployment state * update changelog * backtrack resource package changes, enable test parallelization * cleanup comment * add copyright to new file * resolve paralellization differences after merging automation api preview * no longer need to null deployment instance * Update CHANGELOG.md * whoops - switch to CHANGELOG_PENDING * Update CHANGELOG_PENDING.md move note down to improvements * attempt to exclude dynami assemblies Co-authored-by: Anton Tayanovskyy <anton.tayanovskyy@gmail.com>
