# 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.
