ChangeLog file of LibU - http://www.koanlogic.com/libu/index.html

LibU x.y.z
	- [b64] new module for doing Base64 encoding/decoding
	- [config] '#' can be escaped
	- [uri] add u_uri_is_absolute interface
	- [net] be more tolerant with missing setsockopt() (was causing bind()
			failures on MinGW)
	- [json] fix a memory leak in the indexing interface
	- [hmap] fix bad free() in hmap_clear() when user owns data
	- [queue] avoid complaints about redefined macros
	- [str] fix inconsistency in u_string_detach_cstr which would impact
	        also the json_encode interface in case an empty string was
	        generated

LibU 2.2.0
	- [uri] fix excessively greedy match in IP-literal parser when there is no
	  path component; temp fix in URI builder to take care of IP-literal's
	- [uri] the URI parser set flags while decoding (e.g. tell if the host
	  is IP address or DNS name, or if it is an IP-literal and needs special
	  treatment when encoding.)
	- [daemon] fix compilation on uClinux
	- [buf] u_buf_shrink added
	- [net] fix u_connect_ex timeout re-computation on EINTR to take care
	  of Linux non-POSIX compliant behaviour; also check the updated timeout 
	  value after EINTR to catch corner case underflow conditions.
	- [net] disable u_net_nagle_off() on Minix
	- [array] #undef 'I' (imaginary unit) when including complex.h to avoid
	  name clash -- e.g. with openssl/rsa.h
	- [net] fix u_connect buggy behaviour on EINTR (reported by Mickael Auger)
	- [net] add _ex variants to socket creation interfaces to handle timeouted
	  operations
	- [net] ai_resolv fix: don't ask for AI_CANONNAME when hostname is NULL
	- [hmap] new discard policy U_HMAP_PCY_CUSTOM which allows user to specify
	  object comparison function via u_hmap_opts_set_policy_cmp() ; header
	  cleanup: remove object and policy struct's explicit layout; added
	  u_hmap_{easy_,}clear() ; missing u_hmap_opts_free() calls in test/
	- [test] fix conditional include logics that enables sandboxing
	- [str] don't rely on calloc for initialization of str object internal vars

LibU 2.1.0
	- fix bug in configure when handling the inline keyword support
	- Minix 3.8.1 port
	- fix configure to please OpenBSD when searching for [gs]etsockopt and
	  rusage structure
	- [string] new interface u_string_detach_cstr
	- [lexer] new module to do basic lexical tokenizing 
	- [json] new module to encode/decode/validate JSON objects (RFC 4627)
	- [bst] new binary search tree module
	- [misc] added u_atol and u_atof interfaces
	- [rb] malloc based implementation, both using contiguous (i.e. double
	  sized) and wrapped buffer ; make it work on Windows
	- [test] make it work on Windows
	- [uri] regex-free uri parser (now recursive descent) ; make it work on
	  MinGw ; path is now optional and has default value "/" ; fixed missing 
	  "//" in u_uri_knead_authority()
	- [config] add u_config_walk function to traverse the config tree
	- [carpal] fixed 1.0 compatibility (missing u_con)
	- [net] U_NET_OPT_DGRAM_BROADCAST to set DGRAM client socket broadcast 
	  option
	- [hmap] added u_hmap_count() to get the current number of objects stored
	  into hmap

	- [rb] added new ring buffer module
	- [test] completely revamped, new interfaces
	- [net] module implementation and interfaces revamped
	- [uri] complete support for RFC 3986; added u_uri_knead interface to 
	  create conformant URI strings; added tester
	- [carpal] dbg(), warn(), info(), err() and friends have been prefixed 
	  with "u_" to avoid conflicts with the <err.h> header
	- [config] u_config_print_to_fp with brace delimiters for children records;
	  documentation fixes by Mickael Auger ; don't dump the 'include' 
	  directive when serializing and/or saving an u_config_t object to 
	  file (would break semantical equivalence) 
	- [hmap] added u_hmap_foreach_arg which accepts a user defined parameter
	  that is supplied to the callback function ; add "easy" interface to
	  simplify some common use cases ; updated docs
	- [array] u_array_set_ptr and u_array_get_ptr interfaces changed;
	  added interfaces for intmax_t and uintmax_t types; use C99 types 
	  explicitly (_Complex and _Bool), to avoid clash with bool and complex 
	  possibly #define'd by the user
	- [buf] added u_buf_save interface
	- [misc] some minor fixes
	- [string] minor fixes and cleanup
	- [pwd] internally use u_strtok instead of deprecated u_tokenize
