-;;; Change Log:
-;;
-;; Version 0.2.5
-;; * removed `trie--avl-transform-for-print' and
-;; `trie--avl-transform-from-read', since Emacs has supported printing and
-;; reading circular data structures for a long time now, rendering these
-;; transormers obsolete (note that `print-circle' *must* be enabled now when
-;; printing an avl trie)
-;;
-;; Version 0.2.4
-;; * minor bug-fix to `trie--edebug-pretty-print' to print "nil" instead
-;; of "()"
-;;
-;; Version 0.2.3
-;; * bug-fix in `trie--edebug-pretty-print'
-;;
-;; Version 0.2.2
-;; * added `edebug-prin1' and `edebug-prin1-to-string' advice to prevent
-;; edebug hanging whilst printing large tries
-;;
-;; Version 0.2.1
-;; * bug-fix to result accumulation in `trie--do-regexp-search'
-;;
-;; Version 0.2
-;; * Replaced wildcard searches with regexp searches, using the tNFA.el tagged
-;; non-deterministic finite state automata library. This is both more
-;; general *and* more efficient.
-;; * bug fix in `trie--do-regexp-search'
-;;
-;; Version 0.1
-;; * Initial release (complete rewrite from scratch of tstree.el!)
-;; * Ternary search trees are now implemented as a tree of avl trees, which
-;; has numerous advantages: self-balancing trees guarantee O(log n)
-;; complexity regardless of how the tree is built; deletion is now done
-;; properly.
-;; * Unlike tstree.el, trie.el is general enough to implement all sorts of
-;; tries, not just ternary search trees (though these remain the default).
-;; * Up to "tstree"->"trie" renaming, many functions are drop-in replacements
-;; for tstree.el functions. However, insertion and rank functions are no
-;; longer stored in the data structure, so corresponidng arguments are no
-;; longer optional. A single `trie-complete' function now deals with sorting
-;; completions in both lexical or arbitrary order, the ranking function
-;; being passed as an optional argument in the latter case. And functions
-;; can no longer operate over multiple data structures at once; i.e. they no
-;; longer accept lists of trees as arguments. (These features belong in
-;; higher level libraries, and the efficiency loss is negligible.)
-;; * `trie-wildcard-search' implements efficient shell-glob-like wildcard
-;; searches of tries!
