3.3.0

New Features:

• lock file contains expected hash for pkg dependencies, which allows for safer dependency fetching and paves the way for multi-index support
• Escriptize provider made hookable

Fixes:

• Escriptize based on configured apps only
• Handle escriptize error when a specified app is missing
• Fix filtering of system libraries in escriptize
• Avoid PLT rebuild when files deleted on new dialyzer
• Handle empty PLT or app when using dialyzer
• fix catching not_valid error on dialyzer
• Upgrade relx to 3.21.0
• Bugfix on version resolution compatibility in OTP 17.x and earlier
• Fix Edoc cross-links in umbrella projects
• Print error on too many help arguments
• Fix configuration loading in CT
• template_dir option is documented and made recursive for templates
• Ignore IntelliJ IDEA files in templates
• ssl_verify_hostname was renamed to ssl_verify_fun
• Fix opts check when compiler called with dict opts by plugins
• Fixes for windows environment: 1) copy empty directories when cloning, 2) fix order of arguments in git deps fetching
• Let DEBUG="" and QUIET="" disable the options

The change to the lock file format is the biggest thing to note. It should be compatible with all formats going back to the beta-4 tag, but versions older than 3.3.0 will display warnings and lose the newly added information on the package hashes.

Any lock file generated by an older rebar3 version will be accepted by this one, and new information related to the package hashes will be added. This will allow a safer usage in case the same package is found on multiple indexes or mirrors, but actually has a different hash on there than what is expected by the existing project.

3.2.0

• Fix unicode rendering of deps tree (issue #1140)
• ignore return value of rebar_utils:reread_config in shell provider
• normalize include dirs to absolute paths during compilation
• always recompile if ERL_COMPILER_OPTIONS env var is set
• Compiler source paths in output are now relative
• add support for passing a sys_config to common test
• Expand os ENV proxy support to bootstrap script
• Support ENV config for proxy values
• Write rebar3.crashdump on errors
• Fix compile error case when cover compilation
• Bugfix for upgrading deps of umbrella apps
• Fix minor typo in README
• Handle control sequences in formatted errors
• Don't die when source deps with [raw] are used
• Debug log update
• adjust data_dir_correct test in ct suite
• filter available package versions individually by buildtools
• Fix path command to consider {deps_dir, "deps"} in rebar.config
• fix windows git working directory

The change of note here is that the compiler's output of file paths is now relative to the project (src/myfile.erl) rather than in _build/<profile>/lib/libname/src/myfile.erl.

To retrieve the old behaviour, add {compiler_source_format, build} in your rebar config (you may prefer to do it in the global file). We have also added {compiler_source_format, absolute} for absolute paths (based on the project, not _build).

Second Beta

Breaking improvements:

• major change in dependency handling -- source and package dependencies are now considered equal, so transitive source deps stop overtaking top-level package dependencies.
  May break things for users who relied on that behaviour in mixed repositories
• introduce code coverage options as cover_opts config tuple
• do not install profile-based dependencies of dependencies (stop getting your deps' meck or debug behaviour)
• lock files are sorted to minimize variations in the future and ease diffing

New:

• added proxy support to rebar3 fetches
• SSL certificate validation
• fish shell completions
• add tree command to print the origin of transitive dependencies
• aliased packages such as {uuid, {pkg, uuid_erl}} and {uuid, "1.0.0", {pkg, uuid_erl}} are now supported, where uuid_erl is the package name and uuid the library's
  actual name.
• add support for --file argument in eunit

Fixed:

• fixes to reading app.src.script (for yaws)
• minor template updates
• fixes to profiles application
• reduced memory usage (shell agent, leaks patched)
• fixes for windows (robocopy, symlinks)
• mibs fixes
• fixes to git resource handling (http, custom ssh users supported)
• hooks optimizations
• clear out all usages of 'cd'
• upgrade of dependencies has many improvements
• better error reporting and logging
• major fixes to upgrade and locking mechanisms
• fixes in recompilation of CT suites
• fixes to plugin handling
• directories looking for apps are restricted to what is documented
• escaping paths in shell commands
• edoc provider runs in a 'docs' profile
• clean provider detection of dependencies is fixed
• rebar3 pkgs output is sorted
• fix dialyzer warnings
• fixes to dependency overrides
