-Expected: May 2020

+The 4.5.0 release introduces xpaths in the NACM implementation thus
+completing the RPC and Data node access. There has also been several
+optimizations. Note that this version must be run with CLIgen 4.5, it
+cannot run with CLIgen 4.4 or earlier.

 * Changed output of `clixon_cli -G` option to show generated CLI spec original text instead of resulting parse-tree, which gives better detail from a debugging perspective.

-### Minor changes
+### Optimzations
+* Optimized namespace prefix checks at xml parse time: using many prefixes slowed down parsing considerably
+* Optimized cbuf handling in parsing and xml2cbuf functions: use of new `cbuf_append()` function.
+* Optimized xml scanner to read strings rather than single chars
+* Identify early that trees are disjunct instead of recursively merge in `xml_merge`
+* Optimizations of `yang_bind` for large lists: use a "sibling/template" to use same binding as previous element.
+* Reduced memory for attribute and body objects, by allocating less memory in `xml_new()` than for elements, reducing XML storage with ca 25%
+* Cleared startup-db cache after restart, slashing datastore cache with (best-case) a third.
+* Removed nameserver binding cache for leaf/leaf-list objects.
+* Remove xml value cache after sorting (just use cligen value cache at sorting, remove after use)
 
+### Minor changes
 * Added decriptive error message when plugins produce invalid state XML.
   * Example: `<error-tag>operation-failed</error-tag><error-info><bad-element>mystate</bad-element></error-info><error-message>No such yang module. Internal error, state callback returned invalid XML: example_backend</error-message>`
   * Such a message means there is something wrong in the internal plugins or elsewehere, ie it is not a proper end-user error.
-* Compile-time option: `USE_CLIGEN44` for running clixon-45 with cligen-44.
-  * Temporary fix since cligen-45 have some non-backward compatible behaviour.
-* Cycle optimizations
-  * Optimized namespace prefix checks at xml parse time: using many prefixes slowed down parsing considerably
-  * Optimized cbuf handling in parsing and xml2cbuf functions: use of new `cbuf_append()` function.

-  * Remove xml value cache after sorting (just use cligen value cache at sorting, remove after use)
 * Adapted to CLIgen 4.5 API changes, eg: `cliread()` and `cliread_parse()`
 * Renamed utility function `clixon_util_insert()` to `clixon_util_xml_mod()` and added merge functionality.
 * Sanity check of duplicate prefixes in Yang modules and submodules as defined in RFC 7950 Sec 7.1.4
