Content projection is an important part of Angular. However, it has
never been documented in the Angular documentation set. This topic
attempts to provide the basics of content projection for developers. It
is not a comprehensive guide; rather, it is a starting point that we
can hopefully expand upon in the future.

We recently added a sanity check that ensures that `python` is
available for Bazel. The check relies on `/usr/bin/python` to check
if python is available w/ the correct version. The problem is
that on Windows there is no guarantee that the `/usr/bin` folder
exists, so the `ng-dev release publish` command always fails.
We fix this by just accessing the `env` binary that is also consulted
by scripts executed within Bazel actions. The `env` binary can be
assumed exist in the shell's `$PATH` and can point us to Python
as if it would be executed within Bazel.

Currently we have a common utility method for running commands
in a child process. This method pipes all stdout and stderr, but sets
the `stdin` to `inherited`. This seemed to work as expected in terms of
allowing interactive commands being executed, but it messes with the
TTY in Windows (and potentially other platforms) so that colors and
prompts no longer work properly. See attached screenshot.
We fix this by not inheriting the stdin by default; but exposing
a dedicated method for interactive commands. This results in more
readable and obvious code too, so it's worth making this change
regardless of the TTY issues.

Bazel no longer recommends the use of `remote_execution_properties`
within `platform` definitions. Bazel intends to replace this attribute
with an object literal based attribute called `exec_properties`.
This simplifies the platform configuration and makes it more
readable. Additionally this make inheritance and overriding easier.

Currently if a major release-train in the `release-candidate`/`feature-freeze`
phase becomes `latest`, we intend to set the NPM LTS dist tag for all packages
of the previous major (as the old release train in `latest` moves into LTS phase).
The logic for this exists but the release tool sets the NPM dist tag for
all packages of the new major. This means that the script might error if
a new package is part of the new major; or it could cause a deleted
package to not receive the LTS tag properly.

Some localization workflows want to use the extracted source translation
files directy back in the project as a target translation file.
The extraction process generates files that only contain "source" messages
and not "target" messages. This is actually valid for most translation formats
but currently the Angular localization process expects target translation files
to always contain target messages and will stop with an error in this case.
Now, instead of an error, the translation file loader will log a warning,
and then try to falback to a source message, only erroring if this is also
missing.

Update the statement expressing Angular's supported versions of Node.js. Previously, we stated
that the `current` version of Node.js was supported, however Node.js's `current` version maps
more closely to what we would term a `next` branch and is not expected meant for usage with
production applications. This intention is stated on Node.js Releases page:
> Production applications should only use Active LTS or Maintenance LTS releases.

[`watchr` v4.0.0][1] changes the way watched directories are
scanned/watched, thus causing a great increase in the consumed CPU and
RAM. This affects the performance of the `docs-watch` and transitively
`serve-and-sync` npm scripts.
(For reference, on my local machine it goes from 0% CPU and 275MB RAM
with v3.0.1 to 50% CPU and 10GB RAM with v4+.)
This commit pins `watchr` to version 3.0.1 (which is the latest version
that does not cause performance issues) and disabled automatic updates
via Renovate.

When there are multiple attributes that are marked for i18n translation,
which contain expression bindings, we were generating i18n update op-codes
that did not accurately map to the correct value to be bound in the lView.
Each attribute's bindings were relative to the start of the lView first
attributes values rather than to their own.
This fix passes the current binding index to `generateBindingUpdateOpCodes()`
when processing i18n attributes to account for this.

When including a component in a template, the component's host element
is immediately appended as child of the parent node upon creation.
Hence, `hostElement.parentNode` will be a valid reference. However, if
the parent component is being inserted as an embedded view—through
`ngIf` for example—then the parent's node itself will not have been
inserted yet. This means that we cannot properly determine the position
of the transition namespace, as any `containsElement` check will return
false given that the partial DOM tree has not been inserted yet, even
though it will be contained within an existing transition namespace once
the partial tree is attached.
This commit fixes the issue by not just looking at the existence of a
parent node, but rather a more extensive check using the driver's
`containsElement` method.

This commit changes the reference emitters in the Ivy compiler to prefer
non-aliased exports if they exist. This avoids selecting "private
exports" that may not be stable, e.g. the reexports that have been added
by the View Engine compiler. Such reexports are not stable and are
therefore not suitable to be emitted into partial compilations, as the
output of partial compilations should only reference stable symbols
from upstream libraries.
An alternative solution has been considered where ViewEngine-generated
exports would gain a certain prefix, such that the Ivy compiler could
just exclude those exports (see #41443). However, that solution would
be insufficient in case a library is built using partial compilation and
while depending itself on a VE-compiled library from earlier versions of
Angular, where the magic prefix would be missing. For such libraries,
ngcc would have generated reexports using the declared name if not already
present so this change does result in choosing the correct export.
Because ngcc always generates reexports using the declared name even if
an aliased export is present, this change causes those ngcc-generated
exports to be chosen in downstream libraries using partial compilation.
This is unfortunate as it means that the declared names become
effectively public even if the library author was intentionally
exporting it using an alias. This commit does not address this problem;
it is expected that this should not result in widespread issues across
the library ecosystem.

The legacy-unit-tests-saucelabs job does not need to compile the
compiler compliance tests as they are not used in those tests. Since
the compliance tests can be configured to use specific compiler options,
the generic tsconfig that is used in legacy-unit-tests-saucelabs may not
succeed to compile the compliance tests so this commit excludes those
source files.

Makes the following improvements to the listener instructions to make them slightly smaller and more memory-efficient.
1. Removes the default value from the `useCapture` parameter since it generates more code than just castint to `false`.
2. Removes the `useCapture` and `eventTargetResolver` parameters from `ɵɵsyntheticHostListener` since they won't be generated by the compiler, as far as I can tell.
3. Makes it so that we don't have to return a target name from a `GlobalTargetResolver`. This allows us to save on some memory, because we can return a reference to the target without having to wrap it in an object literal.
DEPRECATIONS:
`EventManagerPlugin.getGlobalEventTarget` is now deprecated and won't be called from Ivy code anymore. Global events will go through `addEventListener`.
