- blue_green for doing migration. Called before Holder.Open finishes. - holdbkg.go added for index lookup. Less wedging between a deadlock and a race. - fix fault under read-only map under lmdb at TestExecutor_Execute_Row_Range/RowIDColumnID by doing cow in roaring. - roaring -tags gofuzz builds again - roaringparanoia build tag added to make test targets in Makefile - add rbf.NewDBWithAllocZero for out-of-bounds memory checks - .circleci/config.yml test-shardwidth-22 with large run container, kept OOM-ing we suspect. Fixes #819
