- Deprecate `dm_get_src()` `tbl.dm()`, `src_tbls.dm()`, `copy_to.dm()`. These functions have better alternatives and use the notion of a "data source" which is being phased out of dplyr (#527).

dm 0.2.0 - Deprecate `dm_get_src()` `tbl.dm()`, `src_tbls.dm()`, `copy_to.dm()`. These functions have better alternatives and use the notion of a "data source" which is being phased out of dplyr (#527). - `*_pk()` and `*_fk()` functions gain an ellipsis argument that comes before `check`, `force` and `rm_referencing_fks` arguments (#520). - `dm_add_pk()` and `dm_add_fk()` support compound keys via the `c()` notation, e.g. `dm_add_pk(dm, table, c(col1, col2))`. `dm_nycflights13()` returns a data model with compound keys by default. Use `compound = FALSE` to return the data model from dm v0.1.13 or earlier (#3). - `dm_get_all_fks()` includes `parent_pk_cols` column that describes the primary key columns of the parent table (#335). - `dm_from_src()` supports the `schema` argument also for MariaDB and MySQL databases (#516). - dm objects now inherit from `"dm_v1"` in addition to `"dm"`, to allow backward-compatible changes of the internal format (#521). - Use hack to create compound primary keys on the database (#522). - `dm_examine_constraints()` and other check functions count the number of rows that violate constraints for primary and foreign keys (#335). - `copy_dm_to(set_key_constraints = FALSE)` downgrades unique indexes to regular indexes (#335). - `rows_truncate()` implemented for data frames (#335). - `dm_enum_fk_candidates()` enumerates column in the order they apper in the table (#335).

because they have alternatives and the concept is being phased out of dplyr.
