| # CHANGELOG | ||
|
|
||
| This is a manually generated log to track changes to the repository for each release. | ||
| Each section should include general headers such as ### Implemented enhancements | ||
| and **Merged pull requests**. All closed issued and bug fixes should be | ||
| represented by the pull requests that fixed them. This log originated with Singularity 2.4 | ||
| and changes prior to that are (unfortunately) done retrospectively. Critical items to know are: | ||
|
|
||
| - renamed, deprecaed, or removed commands | ||
| - defaults that are changed | ||
| - backward incompatible changes (recipe file format? image file format?) | ||
| - migration guidance (how to convert images?) | ||
| - changed behaviour (recipe sections work differently) | ||
|
|
||
|
|
||
| ## [v2.4.1](https://github.com/singularityware/singularity/tree/development) (development) | ||
|
|
||

| [Full Changelog](https://github.com/singularityware/singularity/compare/2.3.2...2.4) | ||
|
|
||
| ### Implemented enhancements | ||
|
|
||
| - a new `build` command was added to replace `create` + `bootstrap` ([build](https://singularityware.github.io/docs-build-container)) | ||
| - default image format is squashfs, eliminating the need to specify a size | ||
| - for development build supports `--sandbox` (folder) and `--writable` (ext3) | ||
| - a `localimage` can be used as a build base, including ext3, sandbox, and other squashfs images | ||
| - singularity hub can now be used as a base with the uri `shub://` | ||
| - support has been added for instances (services) including network namespace isolation under the `instances` group of commands. | ||
| - [singularity registry](https://www.github.com/singularityhub/sregistry) is released and published | ||
| - [Standard Container Integration Format](https://singularityware.github.io/docs-apps) apps are added to support internal modularity and organization. | ||
| - [build environment](https://singularityware.github.io/build-environment) is better documented | ||
| - Persistent Overlay | ||
| - Container checks | ||
| - Tests for instance support | ||
| - Wrapper for create | ||
| - Group instance commands | ||
| - Group image commands | ||
| - Bash completion updates | ||
|
|
||
| ### Deprecated | ||
| - the `create` command is being deprecated in favor of `image.create` | ||
| - `bootstrap` is being deprecated in favor of `build` (will work through 2.4) | ||
| - `expand` is being deprecated in favor of `image.expand`, and no longer works on images with headers (meaning after they are built). | ||
| - `export` is being deprecated and added to the image command group, `image.export` | ||
| - the `shub://` URI no longer supports an integer to reference a container | ||
|
