v3.6.0

Install the Python packages from the Dockerfile  #minor (#15)

The Dockerfile is now the canonical way to set up the system to run
mkroot. mkroot's job is _only_ to copy stuff from the real / to the
rootfs, so it shouldn't be installing stuff itself.

v3.5.0

Refactor how the Docker images are built  #minor (#14)

It turns out that since Docker images are additive, and the runtime
container was depending on the container that runs mkroot, and that
generates _tons_ of files, the resulting container ended up having ~2x
the number of files, just to be deleted immediately in the runtime
container. This caused zero disk savings.

Now the container that runs mkroot is a completely separate one, so
there's no duplication in the runtime container!

v3.4.0

Add a way to preserve stdio  #minor

This change makes it possible to use stdio across the compiler. It's
only enabled with --disable-sandboxing, because that might leak a file
descriptor that was open outside of the container, defeating the whole
purpose.

v3.3.0

Refactor how the JavaScript files are obtained #minor (#12)

This change moves the JavaScript file obtention to the Dockerfile. This
simplifies mkroot a bit and makes it possible to run npm later to
install stuff.

v3.2.0

Improve release process (#11)

We almost never want to not bump the version, since rebase merges are
possible.

Also, since the omegaup package was introduced, we need a new container,
so this is a #minor release.

v3.1.0

Install libkarel from PyPI (#9)

This change uses the PyPI wheel instead of just copying the .py file
from GitHub.  #minor

v3.0.1

Build using C++20

This change adds the --std=c++2a flag to start building stuff with
C++20.

v3.0.0

Add the `--disable-sandboxing` flag  #major

This change adds the `--disable-sandboxing` flag to omegajail. This is
very dangerous to use, but it's also the only way one can run omegajail
while inside a Docker container, without requiring such container to run
unprivileged.

v2.0.0

Add standalone versions of the grader and runner

This change includes a standalone version of the grader and runner. Its
main use is going to be to compare the differences in behavior or an old
rootfs and a new one.

v1.0.3

This is the last release that uses the Bionic container.
