2022/03/25: The -Wrace_conditions Dialyzer flag was removed as it is no longer available starting from OTP 25. 2022/05/20: Relx has been updated to v4. Relx v4 is no longer an escript, therefore breaking changes were introduced. The `RELX`, `RELX_URL` and `RELX_OPTS` variables were removed. The `relx` project must be added as a `DEPS`, `BUILD_DEPS` or `REL_DEPS` dependency to enable building releases. For example: `REL_DEPS = relx`. Relx itself has had some additional changes: the `start` command has been replaced by `daemon`, and configuration defaults have changed so that you may need to add the following to your relx.config file: ``` erlang {dev_mode, false}. {include_erts, true}. ``` 2022/05/31: Xref support has been rewritten. Erlang.mk no longer uses the xref_runner, instead implementing its own interface. This new interface is more flexible and more powerful: it supports both checks and informational analyses as well as the Xref query functions that use the powerful Xref language to perform custom queries. Erlang.mk can also run analyses and queries against all dependencies as well as Erlang/OTP applications. 2023/05/12: Rebar3 is now used for autopatch instead of Rebar2. `make distclean` or `rm -rf .erlang.mk` might be required after updating Erlang.mk. Moving to Rebar3 increases compatibility now that few maintained projects are using Rebar2. For compatibility reasons the variables to point to a different rebar are now REBAR3_GIT and REBAR3_COMMIT. 2023/05/12: A number of broken packages have been removed. They were all unmaintained and there's a low chance that this will break anyone's project. 2023/05/15: Protobuff compilation with `gpb` now uses the `{use_packages, true}` option. 2023/05/15: Experimental support for caching git and hex dependencies has been added. Set `CACHE_DEPS=1` to enable. 2023/05/16: Remove support for HiPE and ErlLLVM.
