## v2.2.2 (2021-06-08)

- Added a2rule, a database tool for ARPA2 Policy Rules
- Added a2id-keygen, for ARPA2 Signed Identities

## v2.2.1 (2021-06-07)

- Bugfix release for ARPA2 Groups
- Added default Service Key to `group_iterate()`
- Welcome + characters in local-part during `a2id_parse_remote()`
- Install `<arpa2/group.h>`
- ARPA2 Group database tooling: `a2access add|del|get member ... [identity ...] [marks ...]`

## v2.2.0 (2021-06-05) 

- Actor Identity and Group Iteration
- Rules can store =g<scene>+<actor> or =g<scene>+<actor>@<xsdomain> attributes 
- Get an a2act_t Actor Identity as part of access_comm() and access_document()
- This functions as a local alias <scene>+<actor>@<xsdomain> for a Remote Identity
- Groups see this local alias as <group>+<member>@<xsdomain> but are still similar 
- Group Iteration yields the reverse mapping, namely a delivery address per group member
 
This completes the plan initiated with v2.0.0,
- 2.0.0 ("Identity, Selector, Iterator")
- 2.1.0 ("Access Control") 
- 2.2.0 ("Group, Identity Mapping")

- Bugfix release
- a2access.c wrote rules without trailing NUL character
- access_comm() did not produce the API-documented default Service Key

- Bugfix release
- Resolved database value partial overwrite of restkey
- Gotten somewhat working add/get behaviour from a2access

Bugfix release.  Fixes in rules database iteration.

# Minor functional updates

- Install missing include files (bugfix)
- Parse ARPA2 Remote Identities with the full local-part as userid

- Bugfix release
- Document Access Name parsing corrections
- Issue #36, Lingering sockets for binds to non-zero ports
- Removed deprecated Reuse support

## Access Control in release v2.1.0 (2021-03-19)

- Access Control added to ARPA2 Common as libarpa2common.so
- Policy Rules form a general layer of Rulesets, Rules being simple instructions
- Rules make callbacks for ~selector %RIGHTS =xvavalue ^trigger endrule endruleset
- Access Control builds layers on top of Policy Rules
- Communication Access states whether mary@example.org may talk to john@example.com
- Document Access decides whether mary@example.org may access //<volume>/<path>

- Strike v2.0.3 from history, it was a mistake
- Fixed signature timestamping issues in tests (which varied with the test day)
- Fixed socket structure storage sizes (making life easier for library users)
- Fixed util.h includes

Including header files and code utilities that were spread around our projects: except.h, com_err.h, snoprintf.[ch], socket.[ch].

* Bugfix in short-lived test signatures.
  * Documentation improvements.

This is a major rework of the library.  It delivers `libarpa2id.so` as described in `<arpa2/identity.h>` and `IDENTITY.MD`.

The release plan for the coming time is:

  * 2.0.0 ("Identity, Selector, Iterator")
  * 2.1.0 ("Access Control")
  * 2.2.0 ("Group, Identity Mapping")

Release v0.7.2
