 # Welcome to conda-package-handling's documentation!
 
-`conda-package-handling` is the library `conda` uses to handle `.conda` and
-`.tar.bz2` [conda
+`conda-package-handling` is a library and command line utility used to handle
+`.conda` and `.tar.bz2` [conda
 packages](https://docs.conda.io/projects/conda/en/latest/user-guide/concepts/packages.html).
 
-It includes a `cph` command-line utility for manipulating new- and old-format
-conda packages.
+`conda` and `conda-build` use `conda_package_handling.api` to create and extract
+conda packages. This package also provides the `cph` command line tool to
+extract, create, and convert between formats.

-```{include} ../README.md
+## A new major version
+
+As of version 2.x, `conda-package-handling` provides a backwards-compatible
+wrapper around
+[`conda-package-streaming`](https://conda.github.io/conda-package-streaming/),
+plus additional package creation functionality not found in
+`conda-package-streaming`. `conda-package-handling` always expects to read and
+write to the filesystem. If you need a simpler API to extract or inspect conda
+packages, check out
+[`conda-package-streaming`](https://conda.github.io/conda-package-streaming/).
+
+Version 2.x is approximately two times faster extracting `.conda` packages, by
+extracting `.conda`'s embedded `.tar.zst` without first writing it to a
+temporary file. It uses
+[`python-zstandard`](https://github.com/indygreg/python-zstandard) and the
+Python standard library instead of a custom `libarchive` and so is easier to
+build. Extraction does not `chdir` to the output directory, and is thread-safe.
+
+Version 2.x creates `.conda` packages slightly differently as well.
+
+* `.conda`'s `info-` archive comes after the `pkg-` archive.
+* Inside `.conda`, the `info-` and `pkg-`'s ZIP metadata use a fixed timestamp,
+  instead of the current time - can be seen with `python -m zipfile -l
+  [filename].conda`.
+* `.conda`'s embedded `.tar.zst` strip `uid`/`gid`/`username`/`groupname`
+  instead of preserving these from the filesystem.
+* Both `.conda` and `.tar.bz2` are created by Python's standard `zipfile` and
+  `tarfile` instead of `libarchive`.
+
+No particular attention has been paid to archiving time which will be dominated
+by the compression algorithm, but this also avoids using a temporary `.tar.zst`.
+
+## Overview
+
+There are two conda formats. The new conda format, described at [.conda file
+format](https://docs.conda.io/projects/conda/en/latest/user-guide/concepts/packages.html?highlight=format#conda-file-format),
+consists of an outer, uncompressed ZIP-format container, with 2 inner compressed
+.tar files. It is designed to have much faster metadata access and utilize more
+modern compression algorithms. The old conda format is a `.tar.bz2` archive.
+
+The cph command line tool can transmute (convert) the old package format to the
+new one, and vice versa.
+
 ```
+cph transmute mkl-2018.0.3-1.tar.bz2 .conda
+```
+
+The new package format is an indexed, uncompressed zip file that contains two
+Zstandard-compressed tarfiles. The info metadata about packages is separated
+into its own tarfile from the rest of the package contents. By doing this, we
+can extract only the metadata, for speeding up operations like indexing.
+
+And, the Zstandard algorithm is much, much faster to decompress than bz2.
+
+Package creation is primarily something that conda-build uses, as cph only
+packages but does not create metadata that makes a conda package useful.
+
+```
+cph create /path/to/some/dir my-cute-archive.conda
+```
+
+This would not necessarily create a valid conda package, unless the directory
+being archived contained all the metadata in an "info" directory that a standard
+conda package needs. The .conda file it creates, however, uses all the nice new
+compression formats, though, and you could use cph on some other computer to
+extract it.
+
+## Development
+
+Install this package and its test dependencies; run tests.
+
+```
+pip install -e ".[test]"
+pytest
+```

 All sorted issues will be reviewed by sorting engineers during a weekly Refinement meeting in order to understand how those particular issues fit into the short- and long-term roadmap of `conda`. These meetings enable the sorting engineers to get together to collectively prioritize issues, earmark feature requests for specific future releases (versus a more open-ended backlog), tag issues as ideal for first-time contributors, as well as whether or not to close/reject specific feature requests.

 #### What is the purpose of having a "Backlog"?
@@ -137,15 +140,6 @@
 Issues are "backlogged" when they have been sorted but not yet earmarked for an upcoming release. Weekly Refinement meetings are a time when the `conda` engineers will transition issues from "[Sorting][project-sorting]" to "[Backlog][project-backlog]". Additionally, this time of handoff will include discussions around the kind of issues that were raised, which provides an opportunity to identify any patterns that may point to a larger problem.
 
 
-#### What is the purpose of a "development sprint"?
-
-After issues have been sorted and backlogged, they will eventually be moved into the "Sprint Candidate", "Short-Term", "Medium-Term", "Long-Term", or "No Time Frame" sections of the [Backlog tab of the Planning board][project-backlog] and get one or more sprint cycles dedicated to them.
-
-The purpose of a development sprint is to enable a steady delivery of enhancements, features, and bug fixes by setting aside pre-determined portions of time that are meant for focusing on specifically-assigned items.
-
-Sprints also serve to focus the engineering team's attention on more accurate planning for what is to come during the entire release cycle, as well as keep the scope of development work concise. They enable the setting aside of dedicated time for the engineers to resolve any problems with the work involved, instead of pushing these problems to the end of the release cycle when there may not be any time remaining to fix issues.
-

 #### How does labeling work?
 
 Labeling is a very important means for sorting engineers to keep track of the current state of an issue with regards to the asynchronous nature of communicating with users. Utilizing the proper labels helps to identify the severity of the issue as well as to quickly understand the current state of a discussion.

-cph is an abstraction of conda package handling and a tool for extracting,
-creating, and converting between formats.
-
-There are two conda formats. The new conda format, described at [.conda file
-format](https://docs.conda.io/projects/conda/en/latest/user-guide/concepts/packages.html?highlight=format#conda-file-format),
-consists of an outer, uncompressed ZIP-format container, with 2 inner compressed
-.tar files. It is designed to have much faster metadata access and utilize more
-modern compression algorithms. The old conda format is a `.tar.bz2` archive.
-
-One can transmute (convert) the old package format to the new one with cph:
-
-```
-cph transmute mkl-2018.0.3-1.tar.bz2 .conda
-```
-
-One can then test the speed of extracting the old file and the new one:
-
-```

-The new package format is an indexed, uncompressed zip file that contains two
-Zstandard compressed tarfiles. The info metadata about packages is separated
-into its own tarfile from the rest of the package contents. By doing this, we
-can extract only the metadata, for speeding up operations like indexing.

-
-Package creation is primarily something that conda-build uses, as cph does
-absolutely nothing to create metadata that makes a conda package useful.
-However, you may consider it useful to abuse cph's package creation as a way of
-utilizing newer compression formats.
-
-```
-cph create /path/to/some/dir my-cute-archive.conda
-```
-
-Again, this would not necessarily create a valid conda package, unless the
-directory being archived contained all the metadata in an "info" directory that
-a standard conda package needs. The .conda file it creates, however, uses all
-the nice new compression formats, though, and you could use cph on some other
-computer to extract it.
-
-## Development
-
-Install this package and its test dependencies; run tests.
-
-```
-pip install -e ".[test]"
-pytest
-```
-
-## Releasing
-
-Conda-package-handling releases may be performed via the `rever command
-<https://regro.github.io/rever-docs/>`_. Rever is configured to perform the
-activities for a typical conda-build release. To cut a release, simply run
-``rever <X.Y.Z>`` where ``<X.Y.Z>`` is the release number that you want bump to.
-For example, ``rever 1.2.3``.  However, it is always good idea to make sure that
-the you have permissions everywhere to actually perform the release.  So it is
-customary to run ``rever check`` before the release, just to make sure.  The
-standard workflow is thus::
-
-    rever check
-    rever 1.2.3
-
-If for some reason a release fails partway through, or you want to claw back a
-release that you have made, rever allows you to undo activities. If you find
-yourself in this pickle, you can pass the ``--undo`` option a comma-separated
-list of activities you'd like to undo.  For example::
+Create and extract conda packages of various formats
 
-     rever --undo tag,changelog,authors 1.2.3
+`conda` and `conda-build` use `conda_package_handling.api` to create and extract
+conda packages. This package also provides the `cph` command line tool to
+extract, create, and convert between formats.
 
- Happy releasing!
