What's Changed

A major evolution of Ansible Builder's Execution Environment definition format, with overall themes of increased flexibility and minimizing required manual alterations of generated build contexts. New features of the version 3 Execution Environment definition include:

* Use of vanilla RHEL-ish container images instead of specially-crafted base and builder images (tested against Fedora, CentOS Stream 8/9, UBI9 and others).
* Injection of custom build steps before and after every build stage.
* Copying arbitrary files from the builder host into the generated container build context (which can then be copied into intermediate/final container images as needed with custom build steps).
* Declarative bootstrapping of Python, Ansible Core, and Ansible Runner (in addition to roles/collections, of course).
* Inline definition of Python/bindep/role/collection requirements in Execution Environment YAML (external files also still supported).
* Customization of final container initialization ENTRYPOINT, USER, and CMD (with verified automatic defaults).
* Dynamic builder image from user-specified base image- specifying a builder image is no longer required (or allowed).
* Faster builds due to linear stage inheritance and removal of forced OS package upgrades.
* Numerous bugfixes and minor enhancements... see documentation for examples.


Breaking Changes

* The `--squash` argument to `build` now defaults to `off` for all container runtimes. This allows build caches to function by default for `podman` during development and testing, at the cost of more intermediate layers in the resultant image. Manually specifying `--squash new` is suggested for CI and production builds when using `podman` to minimize the size and number of intermediate layers.

* Forced OS package manager upgrades are no longer performed in individual build stages by default. If a full OS package upgrade is desired, add a new build directive to `prepend_base` under `additional_build_steps` (e.g., `- RUN dnf upgrade -y`) to upgrade packages on the base image. The upgraded packages will be reflected in all subsequent build stages.

What's Changed

A 3.0 evolution of ansible-builder to address a number of pain points with current ansible-builder. New features available with the new version 3 of the execution environment definition file include:

* Allows use of vanilla RHEL-ish container images instead specially-crafted images- check out demo/v3_demo/execution-environment.yml for a working sample tested with Fedora, CentOS Stream 8/9, UBI9...
* Allows injection of custom before/after build steps at every build stage.
* Allows copying arbitrary files from the builder host into the generated container build context (which can then be copied into intermediate/final container images as needed with custom build steps).
* Allows declarative bootstrapping of Python, Ansible Core, and Ansible Runner (in addition to roles/collections, of course).
* Allows inline definition of EE Python/bindep/role/collection requirements.
* Allows customization of ENTRYPOINT and CMD.
* Specifying a builder image is no longer needed (or allowed).
* Many other goodies... see documentation for examples.
