0.9.2 - detach cleanup, replace and documentation (r674)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[dom]  -Change: API CHANGE: lht_dom_node_alloc() allocates floating node -
                there should be no node with doc field set but not linked
                in the tree or part of the unlinked list
[dom]  -Rename: API CHANGE: _tree_ prefixed calls to _dom_ prefixed calls
[dom]  -Change: move internal functions from dom.h to dom_internal.h and document
                the rest
[dom]  -Add: auto-freeing on detach (when detach_doc is 1 and root is removed)
[dom]  -Add: list and hash insert/append require detached node and move them
             under the current doc and set parent
[dom]  -Fix: allow appending nodes to floating subtrees
[tree] -Fix: memmove() missing indirection bug when moving table rows/cols
[tree] -Add: node replace function
[tree] -Fix: when replacing cell of a table, make sure the detached node is
             moved into the document
[tree] -Fix: lth_tree_detach() works for already detached nodes and root nodes
[doc]  -Add: document-tree-node API concepts: unlinking/detaching/deleting,
            floating nodes, iterators, debug/diagnostic calls
[tests] -Add: table row/col insert/delete testes
[tests] -Add: Tests.exclude lists local exclusions of test cases
[tests] -Fix: sort ls output before generating Makefile.test - this will
              avoid unintended changes
[util] -Add: prepare marshaler for pointers:
             - expect descriptions to be a hash of multiple structs
             - each struct must start with a type name (anonymous)
             - build field cache in marshaler


0.9.1 - core lib implementation (r618)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 [lib] -Fix: lht_err_t return values are always positive
 [build] -Change: central Makefile.common for a module-based build system that handles cross-dependencies better
 [dom] -Fix: when growing table, don't realloc cols beyond cols
 [dom] -Split: move dangerous internal calls from dom.h to new dom_internal.h
 [tree] -Add: a function that determines whether a node is under another in the tree
 [tree] -Add: lht_tree_path_build() - reverse path build from node ptr
 [tree] -Add: lht_tree_sy_is_broken()
 [tree] -Add: hash del node function
 [tree] -Add: hash len function
 [tree] -Add: generic node detach
 [tree] -Add: node del function
 [tree] -Add: subtree merge code (empty symlink always fails to merge as specified in the doc since r600)
 [tree] -Add: symlink helper API and DFS implementation looking for symlinks and broken symlinks within a subtree
 [tree] -Fix: . and .. should behave as specified: . is ->parent, .. is ->parent->parent
 [tree] -Fix: tree.h does depend on dom.h - include it; include protection in tree.h
 [util] -Update: old PE_ references in validator lib
 [util] -Update: lht_marshaller for the "new" lht_ prefixes in the lib
 [util] -Add: lhtview - simple CLI for interactive inspection of lihata trees
 [util] -Fix: validator lib doesn't use stack_t (causes namespace collision on macosx)

0.9.0 - initial release
~~~~~~~~~~~~~~~~~~~~~~~
 -Add: documentation: language design, design decisions and some API docs
 -Add: implementation of liblihata: fully functional event and dom parser
       and most of the tree handlers, including paths and basic symlink
       support
 -Add: example app: simple config load
 -Add: utilities: validator, flat marshaller
