  * Affects all parts of the system, including datastore, backend, restconf and cli.
* Invalid api-path syntax (eg non-matching yang) error changed from 412 operation-failed to 400 Bad request invalid-value, or unknown-element.

# Clixon Changelog
## 4.2.0 (Expected: September)
## 4.2.0 (Expected: October)

* If dropped temporary, you can restore privileges with `restore_priv()`
### API changes on existing features (you may need to change your code)
* Stricter handling of multi-namespace handling
* This occurs in cases where there are more than one XML namespaces in a config tree, such as `augment`:ed trees.
* Affects all parts of the system, including datastore, backend, restconf and cli.
* Examples of a mandated stricter usage of a simple augment `b` of symbol `a`. Assume `a` is in module `mod1` with namespace `urn:example:a` and `b` is in module `mod2` with namespace `urn:example:b`:
* RESTCONF: `GET http://localhost/restconf/data/mod1:a/mod2:b`
* NETCONF: `<a xmlns="urn:example:a" xmlns:b="urn:example:b"><b:b>42</b:b></a>`
* XPATH (in edit-config filter): `<filter type="xpath" select="a:a/b:b" xmlns:a="urn:example:a" xmlns:b="urn:example:b"/>`
* RESTCONF error reporting
* Invalid api-path syntax (eg non-matching yang) error changed from 412 operation-failed to 400 unknown-element / invalid-value. For example, change from
```
HTTP/1.1 412 Precondition Failed
{"ietf-restconf:errors":{"error":{"error-type":"protocol","error-tag":"operation-failed","error-severity":"error","error-message":"No such yang module: badmodule"}}}
```
to:
```
HTTP/1.1 400 Bad Request
{"ietf-restconf:errors":{"error":{"error-type":"application","error-tag":"invalid-value","error-severity":"error","error-message":"No such yang module: badmodule"}}}
```
* Invalid api-path syntax (eg non-matching yang) error changed from 412 operation-failed to 400 Bad request invalid-value, or unknown-element.
* Typical installation should now add a `clicon` user (as well as group)
* New clixon-config@2019-09-11.yang revision
* Added: CLICON_BACKEND_USER: drop of privileges to user,

### Corrected Bugs
* See "Stricter handling of multi-namespace handling" in API-changes above.
* Hello netconf candidate capability misspelled, mentioned in [Can clixon_netconf receive netconf packets as a server? #93](https://github.com/clicon/clixon/issues/93)
* [Cannot write to config using restconf example #91](https://github.com/clicon/clixon/issues/91)
* Updated restconf documentation (the example was wrong)
