• reset default profile app plugins to empty if at the top level (#1885)
• properly support top level app erl_opts from REBAR_CONFIG os var (#1889)
• only print skip warning if version is different (#1886)
• add option to compiler provider to only build dependencies (#1888)
  • add compile type for dynamic project compilation (allows for overriding the entire compilation process of an individual application, for example so Elixir projects that are built with mix)
  • rebar_compiler is a new behaviour that a plugin can implement to be called on any use of the compile provider to compile source files and keep track of their dependencies.
  • only include modules in the .app modules list that are from src_dirs while leaving out those from extra_src_dirs
• warn if the matched package is retired, skip prerelease (#1897)
• upgrade relx and set base_dir in overlay_vars (#1902)
• compiler behaviour (#1893)
• Bump bbmustache and fix templates (#1862)
• Fix sample config punctuation (#1890)

From 3.7.0-rc1:

• support for hex v2, multiple repository fetching, private organizations (#1884)
  • see rebar3_hex for instructions authenticating against private organizations and working with repositories
• fix: only eval config scripts and apply overrides once per app (#1879)

• support for hex v2, multiple repository fetching, private organizations (#1884)
  • see rebar3_hex for instructions authenticating against private organizations and working with repositories
• fix: only eval config scripts and apply overrides once per app (#1879)

• Reload logger config in shell according to sys.config
• add report in the effects_code_generation, as it is the short form for both report_errors and report_warnings preventing some unnecessary re-compiling
• Friendlier output on include_lib errors
• Bump certifi to update certificates
• fixed typo erl_first_files
• smarter shell code reloading, add env options for refresh_paths & refresh_paths_blacklist
• Warn but succeed when atoms are passed to erl_first_files

Fixes to relx and other calls that failed for eperm errors in OTP-21.

This is the first important release to support OTP-21.0 officially, rather than just release candidates. There are some new features:

• upgrades to relx to 3.25.0 introduce support for OTP-21's 'sys.config.src' files, which allow automatic replacement of variables in sys.config files, without needing to use set RELX_REPLACE_OS_VARS, and without having to wrap them in strings to work. It also contains a bunch of bugfixes.
• Introduce support of del operations for overrides, which allow to unset specific values from lists such as erl_opts in dependencies
• Add hooks to the upgrade command
• Add --start-clean flag to rebar3 shell

There are also plenty of bugfixes:

• Bump cth_readable for OTP-21 compat
• upgrade bbmustache to 1.5.0
• run compile provider in default namespace from bare compiler, fixing some build issues in mix builds
• Resolve string vs list crashing rebar3 erl_first_files
• Create ERLANG_LIB_*_erl_interface environment variables only if erl_interface exists
• Auto-boot main app in OTP app project templates
• Use maps for child spec example in templates

This is a patch release fixing a few things with 3.5.2:

• Restore default templates in bootstrapped rebar3
• start at least one async thread in async thread poll
• Logger support in cth_readable, and compact CT output

Do note that Erlang R16B support has officially ended in order to support Erlang/OTP-21-rc1, given that logging handling required maps, which did not exist back in R16. If you need R16B support, the old rebar3 releases should work for a good while.

A new compact format for common test output has been added and made default, equivalent to --readable=compact. You can revert to previous behaviour with --readable=true or cancel all reformatting of output with --readable=false as before.

• Support Erlang/OTP-21
• ensure destination directory exists before copying data to it and fix src_dirs symlinking logic
• Display warnings when global cache dirs are read-only
• Bump cth_readable to 1.3.4 to restore eunit macro formatter functionality and lager compat
• Reload pre-started apps running in first shell boot with new sys.config
• Fix local upgrade etag handling
• Fix precedence rules of erl_opts for test profile
• Display rebar.config.script errors for better diagnosing of issues
• Handle Schema-less Proxy URLs in ENV vars
• Fix quotes handling in packages etag values
• Remove noisy debug message about internal state
• force an order on multiple profiles to fix inconsistencies on repeated runs
• use debug level for logs about bad package versioning
• don't attempt to retry finding missing packages when updating index
• Functions allowing providers and plugins to set ENV vars have been exposed
• do not return first hex package version for a constraint with no match
• Set unicode option for standard_io at entry point
• fix hooks and plugins usage when cleaning build artifacts for deps
• upgrade erlware commons and relx for various bug fixes
• Fix alias provider argument passing

Release 3.5.0 adds some new features!

• Support minimal coverage enforcement in tests with cover --min_coverage=0..100
• add eunit and ct option to set coverdata file name (--cover_export_name)
• Add experimental support for ct --retry option, allowing to replay previously failed test cases.

The alias plugin is a particular highlight letting you define your own rebar3 commands out of sequences of existing ones.

Multiple fixes were also added:

• Update to the bootstrap script fixing some file handling and windows issues
• Prevent escriptize failure when ebin/ has subdirectories
• Prevent plugin unloading from killing currently running command (soft-purge in-compile)
• Fix file handling on Windows 7
• fix code path handling when validating plugins
• Disable color in git log commands when enabled globally
• Update manpages

• Allow silencing skip warnings when fetching deps
• Fix warning in CT output control when using lager
• Fix compilation crash for custom resources with dynamic versions
• Fix a regression in relx eating config file lines and fix windows nodetool
• Make debug_info rules clear for profile composition
