# pkgload 1.2.4

* Lionel Henry is now the maintainer.

* `load_all()` automatically registers package translations, if found.

# pkgload 1.2.3

* pkgload now forces all bindings on unload. This fixes errors and inconsistencies when dangling references force lazy bindings after unload or reload.

* `load_all()` now restores S3 methods registered by third party packages (#163).

* `load_dll()` will now preserve the DLL name when loading instead of always using the package name. This allows packages to include DLL's with different names (#162, @dfalbel).

# pkgload 1.2.2

# pkgload 1.2.1

* `unload()` no longer unregisters methods for generics of the package being unloaded. This way dangling references to generics defined in the stale namespace still work as expected (r-lib/vctrs#1341).
* `load_all()` will now work for packages that have testthat tests but do not have testthat installed (#151)
* The `pkgbuild` dependency has been moved to `Suggests`, as it is only needed for packages with compiled code.

* `load_all()` will now work for packages that have testthat tests but do not have testthat installed (#151)

* `load_all(warn_conflicts = TRUE)` becomes more narrow and only warns when a *function* in the global environment masks a *function* in the package, consistent with the docs (#125, #143 @jennybc).

* `load_all()` no longer does a comprehensive check on the `DESCRIPTION` file when loading, instead just checking that it exists and starts with Package (#149, @malcolmbarrett)

* `unload()` no longer warns when it can't unload a namespace.

# pkgload 1.2.0

* Fix test failure in R 4.1 with regards to S4 method registration

* `load_all()` now preserves existing namespaces in working order. In
  particular, it doesn't unload the package's shared library and keeps
  it loaded instead. When reloading, a copy of the SO for the new
  namespace is loaded from a temporary location. These temporary SOs
  are only unloaded on GC and deleted from their temporary location
  via a weak reference attached to the namespace.

  This mechanism ensures that lingering references to the namespace
  keep working as expected. Consequently the namespace
  propagation routine that was added to pkgload as a workaround has
  been removed.

  Note that `.Call()` invocations that pass a string symbol rather
  than a structured symbol may keep crashing, because R will look into
  the most recently loaded SO of a given name. Since symbol
  registration is now the norm, we don't expect this to cause much
  trouble.

* `load_all()` no longer forces all bindings of a namespace to avoid
  lazy-load errors. Instead, it removes exported S3 methods from the
  relevant tables.

  - This improves the loading behaviour with packages that define
    objects in their namespaces lazily (e.g. with `delayedAssign()`).

  - This also makes `load_all()` more predictable after a method has
    been removed from the package. It is now actually removed from the
    generic table. It would previously linger until R was restarted.

* If `load_all()` attaches testthat, it automatically suppresses conflicts.

# pkgload 1.1.0

* `dev_example()` now works after removing an inconsistent call to `load_all()` (@riccardoporreca, #122).

* `load_all()` now issues a warning if exported objects conflict with objects defined in the global environment (#112)

* `run_example()` arguments `run` and `test` are deprecated in favor of the (hopefully) more clear `run_dontrun` and `run_donttest` (#107).

* Internal fixes for compatibility with the future 4.1.0 release.

# pkgload 1.0.2

* `shim_question()` now works for topics from the R base package that are passed with the double colon operator (e.g. `base::min`) (@mdequeljoe, #99).

* `load_all()` now allows using explicitly qualified, exported names in test
  helpers (@klmr, #95).

* `load_all()` gains a `compile` argument which controls more finely whether to
  compile the code or not. The `recompile` argument is now deprecated and will
  be removed in a future version of pkgload.

# pkgload 1.0.1

* `unload()` now only removes S4 classes which were generated in the package
  being unloaded (#75)

* `help()` will no longer error when trying to load package level help (#67).

* Trailing slashes now removed from all paths, which fixes issues on Windows (#73).

* `load_dll()` now fixed in R-devel (#77).

* The help shim's now work for `:::` inputs (#72).

# pkgload 1.0.0

* `load_all()` now updates imports of dependent packages when a package is
  reloaded (#59).

* `load_all()` now assigns `DESCRIPTION/Depends` to `.Depends` object of 
  package environment. (@yiufung pkgload#61)

* `load_all()` now attaches `testthat` if the `attach_testthat` option is
  `TRUE`. This allows `load_all()` to more closely mimic the testing
  environment. (#56)

* `check_dep_version()` and `check_suggested()` are now exported.

* `check_dep_version()` now emits a warning and returns `FALSE` rather than
  aborting. (#47)

* Package imports are now exported when using `load_all()`. This behavior can
  be disabled by using `load_all(export_imports = FALSE)`.

* The `as.package()` and `is.package()` functions have been removed.

* `load_code()`, `load_data()`, `load_dll()`, `load_all()`, `parse_ns_file()`
  all now take an explicit path rather than a path or a `package` object.

* `imports_env()`, `ns_env()`, `pkg_env()` and `unload()` now take a package
  name rather than a path or a `package` object.

* `run_example()` now works on R 3.1.

* `unload()` now unloads S4 classes for packages loaded with `library()` as
  well as `load_all()` (#46).

* `load_all()` gains a `helpers` option to specify whether or not to
  source testthat helpers. (@pitakakariki devtools #1202)

* `load_all()` now sources the testthat helpers in the namespace environment
  rather than the package environment (#40).

* `load_all()` now sets the `NOT_CRAN` environment variable when it
  sources testthat helpers. It also sets `DEVTOOLS_LOAD` to "true" so
  that you can check whether they are run during package loading.

* `dev_topic_path()` now only returns the last path found, fixing an error
  when a package has both a package function level help with the same name.
  (#21)

* New function `is_dev_package()` to determine if a given package has been loaded
  by `pkgload::load_all()` (#2).

* `load_all()` no longer updates the collate directive. Instead this
  functionality has been moved to `devtools::document()`.

* `dev_help()` now optionally takes a character vector of packages to
  search within.  This replaces `find_topic()`.

* `dev_topic_index_reset()` is now exported, and allows you to reset
  the topic index associated with a given package.

* Added a `NEWS.md` file to track changes to the package.

* Initial release from code spun off from devtools
