# Salt 0.10.4 Release Notes

Salt 0.10.4 is a monumental release for the Salt team, with two new module systems, many additions to allow granular access to Salt, improved platform support and much more.

This release is also exciting because we have been able to shorten the release cycle back to under a month. We are working hard to keep up the aggressive pace and look forward to having releases happen more frequently!

This release also includes a serious security fix and all users are very strongly recommended to upgrade. As usual, upgrade the master first, and then the minion to ensure that the process is smooth.

## Major Features

### External Authentication System

The new external authentication system allows for Salt to pass through authentication to any authentication system to determine if a user has permission to execute a Salt command. The Unix PAM system is the first supported system with more to come!

The external authentication system allows for specific users to be granted access to execute specific functions on specific minions. Access is configured in the master configuration file, and uses the new access control system:

    external_auth:
      pam:
        thatch:
          - 'web*':
            - test.*
            - network.*

The configuration above allows the user thatch to execute functions in the test and network modules on minions that match the web* target.

### Access Control System

All Salt systems can now be configured to grant access to non-administrative users in a granular way. The old configuration continues to work. Specific functions can be opened up to specific minions from specific users in the case of external auth and client acls, and for specific minions in the case of the peer system.

Access controls are configured like this:

    client_acl:
      fred:
        - web\*:
          - pkg.list_pkgs
          - test.*
          - apache.*

### Target by Network

A new matcher has been added to the system which allows for minions to be targeted by network. This new matcher can be called with the -S flag on the command line and is available in all places that the matcher system is available. Using it is simple:

    $ salt -S '192.168.1.0/24' test.ping
    $ salt -S '192.168.1.100' test.ping

### Nodegroup Nesting

Previously a nodegroup was limited by not being able to include another nodegroup, this restraint has been lifted and now nodegroups will be expanded within other nodegroups with the N@ classifier.

### Salt Key Delete by Glob

The ability to delete minion keys by glob has been added to `salt-key`. To delete all minion keys whose minion name starts with 'web':

    $ salt-key -d 'web*'

### Master Tops System

The external_nodes system has been upgraded to allow for modular subsystems to be used to generate the top file data for a highstate run.

The external_nodes option still works but will be deprecated in the future in favor of the new master_tops option.

Example of using master_tops:

    master_tops:
      ext_nodes: cobbler-external-nodes

### Next Level Solaris Support

A lot of work has been put into improved Solaris support by Romeo Theriault. Packaging modules (pkgadd/pkgrm and pkgutil) and states, cron support and user and group management have all been added and improved upon. These additions along with SMF (Service Management Facility) service support and improved Solaris grain detection in 0.10.3 add up to Salt becoming a great tool to manage Solaris servers with.

## Security

A vulnerability in the security handshake was found and has been repaired, old minions should be able to connect to a new master, so as usual, the master should be updated first and then the minions.

### Pillar Updates

The pillar communication has been updated to add some extra levels of verification so that the intended minion is the only one allowed to gather the data. Once all minions and the master are updated to salt 0.10.4 please activate pillar 2 by changing the pillar_version in the master config to 2. This will be set to 2 by default in a future release.
