* Fixed: [very slow execution of load_set_file #288](https://github.com/clicon/clixon/issues/288)
* New `clixon-lib@2021-11-11.yang` revision
* Modified option: RPC stats extended with YANG stats
* Modified `clixon-config@2021-11-11.yang` revision
* Added option:
* CLICON_PLUGIN_CALLBACK_CHECK
* Enable to make plugin context check before and after all callbacks.
* Added statistics for YANG: number of objects and memory used
* Use the treeref no-copy option of CLIgen to reduce memory
* Refactored cli-generation/autocli-start code
* Refactored cligen glue functions to use cligen_eval directly (remove clicon_eval,clixon_cligen_eval)
* Stricter checking of outgoing RPC replies from server
* See [RPC output not verified by yang](https://github.com/clicon/clixon/issues/283)
* This lead to some corrections of RPC replies in system code
* Some openconfig specs seem to have use/when before a "config" which it depends on. This leads to XML encoding being in the "wrong order.
* When parsing, clixon now sorts container/list statements so that sub-statements with WHEN are put last.
* See [Statements given in "load set" are order dependent](https://github.com/clicon/clixon/issues/287)
* Fixed: [Statements given in "load set" are order dependent](https://github.com/clicon/clixon/issues/287)
* Example, assume XML: `<s><![CDATA[ z > x & x < y ]]></s>`
* Previous bevavior:
* JSON: {"s":" z > x & x < y "}
* New behavior:
* JSON: `{"s":"<![CDATA[ z > x & x < y ]]>"}`
* To keep old behavior, set `JSON_CDATA_STRIP` in clixon_custom.h
* Merge branch 'dcornejo-master'
* Broke out pagination callback API from state data callbacks
* New pagination callback API uses new dispatcher from netgate, thanks @dcornejo
* Register callback with: `clixon_pagination_cb_register()`
* Use accessor functions `pagination_offset()`, `pagination_limit()`, etc
* Reverted state data callback API to pre-5.3 (see C/CLI API changes below)
NETCONF hello errors, such as wrong session-id, prefix, namespace terminates session
* Instead of returning an rpc-error reply
Changed YANG PATCH enabling:
* Now: `./configure --enable-yang-patch`
* Before: set YANG_PATCH constant in `include/clixon_custom.h`
Refactored Makefile for static linking
* You need to change all statedata plugin callback for the new pagination feature
* If you dont use pagination you can ignore the values of the new parameters
* See [User manual pagination](https://clixon-docs.readthedocs.io/en/latest/misc.html#pagination)
* The updated callback signature is as follows:
```
int statedata(clicon_handle h,
cvec *nsc,
char *xpath,
pagination_mode_t pagmode, // NEW
uint32_t offset, // NEW
uint32_t limit, // NEW
uint32_t *remaining, // NEW
cxobj *xstate)
```
* The new callback contains parameters for paging
* Goal is to replace ca_statedata callback
* New plugin callback when lock/unlock occurs
* Add `ca_lockdb` tro plugin init to use it.
* Fixed: Typing 'q' in CLI more paging did not properly quit output
* Output continued but was not shown, for a very large file this could cause considerable delay
* Fixed: Lock was broken in first get get access
* if the first netconf operation to a backend was lock;get;unlock, the lock was broken in the first get access.
* Fixed: [Performance issue when parsing large JSON param](https://github.com/clicon/clixon/issues/266)
* Moved strlen() from for end condition
* Fixed debugging of xpath parser
* Eg if YANG is `choice c { leaf x; leaf y }` and XML changed from `<x>42</x>` to `<y>42</y>` the datastrore changed, but was not detected by diff algorithms and provided to validate callbacks.
* Thanks: Alexander Skorichenko, Netgate
* Closer adherence to RFC 7950. Some of this is changed behavior, some is new feature.
* Essentially instead of looking at the referring leaf, context is referred(target) node
* Validation uses referred node
* Validation changed to use type of referred node, instead of just "string"
* Auto-cli
* Changed to use type of referred node for typecheck
* Completion uses referred node
* Required instance / less strict validation
* New: Leafrefs must refer to existing data leaf ONLY IF YANG `required-instance` is true
* Previous: All leafrefs must refer to existing data leaf node
* Fixed: [Autocli does not offer completions for leafref to identityref #254](https://github.com/clicon/clixon/issues/254)
