# covr 3.3.2

* Fix test failures in the development version of R (4.0.0) (#400)

# covr 3.3.1

* Fix inadvertent regression in return visibility when functions are covered.
  covr versions prior to 3.3.0 surrounded each statement in `{` blocks. covr
  3.3.0 switched to using `({`, but this caused an inadvertent regression, as
  `(` will make the result visible it is the last expression in a function.
  Using `if (TRUE) {` restores the previous behavior. (#391, #392)

# covr 3.3.0

## New Features

* New `azure()` function added to make it easy to use covr on [Azure
  Pipelines](https://azure.microsoft.com/en-us/services/devops/pipelines/)
  (#370)

* Work around issues related to the new curly curly syntax in rlang (#379, #377, rlang#813)

* Compiled code coverage has been improved, in particular C++ templates now
  contain the merged coverage of all template instances, even if the instances
  were defined in separate compilation units. (#390)

## Bugfixes and minor improvements

* `codecov()` now includes support for the flags field (#365)
* `codecov` now looks `codecov.yml` for token if `CODECOV_TOKEN` envvar is not
  set (@MishaCivey #349).
* `per_line()` now does not track lines with only punctuation such as `}` or `{` (#387)
* `tally_coverage()` now includes compiled code, like it did previously (#384)

* Define the necessary coverage flags for C++14, C++17 and C++20 (#369).

* `to_cobertura()` now works with Cobertura coverage-04.dtd (@samssann, #337).

* [R6](https://github.com/r-lib/R6) class generators prefixed with `.` are now
  included in coverage results (@jameslamb, #356).

* `package_coverage()` gains option `pre_clean`, set to `FALSE` to disable
  cleaning of existing objects before running `package_coverage()` (@jpritikin, #375)

# 3.2.1

* Fix for regression when testing coverage of packages using mclapply (#335).

# 3.2.0

## Breaking changes

* Previously deprecated `shine()` has been removed. Instead use `report()`.

## New Features

* `file_report()` added when viewing coverage for a single file (#308).

* `display_name()` is now exported, which can be useful to filter the coverage
  object by filename.

* `environment_coverage()` added, mainly so it can be used for `devtools::test_coverage_file()`.

* `gitlab()` function added to create a coverage report for GitLab using
  GitLab's internal pages (@surmann, #327, #331).

* The (optional) dependency on shiny has been removed. `report()` can now be
  built with only DT and htmltools installed.

## Bugfixes and minor improvements

* Fix for gcc-8 gcov output producing lines with no coverage counts in them (#328)

* `impute_srcref()` now handles `...` and drop through arguments in switch
  statements (#325).

* `tally_coverage()` now avoids an error when there are NA values in the source
  references (#322).

* `covr(clean = TRUE)` now cleans the temporary library as well (#144)

* `package_coverage()` now returns the end of the file if there is a test error (#319)

* `report()` now handles reports in relative paths with subdirectories correctly (#329)

* `report()` reworked to look more like codecov.io and to display the overall
  coverage (#302, #307).

* DT explicitly loaded early in `report()` so that failures will occur fast if
  it is not installed. (#321, @renkun-ken).

# 3.1.0 #

## Breaking changes

* `shine()` has been deprecated in favor of `report()`.

## New Features

* Add support for `.covrignore` files (#238), to exclude files from the coverage.

  that are not found automatically (#295, @mb706).

  how parse data is stored in packages.

* Improve behavior of `switch` coverage, it now supports default values and
  fall through properly.

* Add `-p` flag to gcov command to preserve file paths. Fixes a bug where
  gcov output didn't get reported when multiple compiled source files had
  the same name (#271, @patperry)
