1.3  jtc New in alpha3.3:  The definition of word boundaries has been altered
1.3  jtc slightly, to more closely match the usual programming notion that "_"
1.3  jtc is an alphabetic.  Stuff used for pre-ANSI systems is now in a subdir,
1.3  jtc and the makefile no longer alludes to it in mysterious ways.  The
1.3  jtc makefile has generally been cleaned up some.  Fixes have been made
1.3  jtc (again!) so that the regression test will run without -DREDEBUG, at
1.3  jtc the cost of weaker checking.  A workaround for a bug in some folks'
1.3  jtc <assert.h> has been added.  And some more things have been added to
1.3  jtc tests, including a couple right at the end which are commented out
1.3  jtc because the code currently flunks them (complex bug; fix coming).
1.3  jtc Plus the usual minor cleanup.
1.3  jtc
1.2  jtc New in alpha3.2:  Assorted bits of cleanup and portability improvement
1.2  jtc (the development base is now a BSDI system using GCC instead of an ancient
1.2  jtc Sun system, and the newer compiler exposed some glitches).  Fix for a
1.2  jtc serious bug that affected REs using many [] (including REG_ICASE REs
1.2  jtc because of the way they are implemented), *sometimes*, depending on
1.2  jtc memory-allocation patterns.  The header-file prototypes no longer name
1.2  jtc the parameters, avoiding possible name conflicts.  The possibility that
1.2  jtc some clot has defined CHAR_MIN as (say) `-128' instead of `(-128)' is
1.2  jtc now handled gracefully.  "uchar" is no longer used as an internal type
1.2  jtc name (too many people have the same idea).  Still the same old lousy
1.2  jtc performance, alas.
1.2  jtc
1.1  jtc New in alpha3.1:  Basically nothing, this release is just a bookkeeping
1.1  jtc convenience.  Stay tuned.
1.1  jtc
1.1  jtc New in alpha3.0:  Performance is no better, alas, but some fixes have been
1.1  jtc made and some functionality has been added.  (This is basically the "get
1.1  jtc it out the door in time for 4.4" release.)  One bug fix:  regfree() didn't
1.1  jtc free the main internal structure (how embarrassing).  It is now possible
1.1  jtc to put NULs in either the RE or the target string, using (resp.) a new
1.1  jtc REG_PEND flag and the old REG_STARTEND flag.  The REG_NOSPEC flag to
1.1  jtc regcomp() makes all characters ordinary, so you can match a literal
1.1  jtc string easily (this will become more useful when performance improves!).
1.1  jtc There are now primitives to match beginnings and ends of words, although
1.1  jtc the syntax is disgusting and so is the implementation.  The REG_ATOI
1.1  jtc debugging interface has changed a bit.  And there has been considerable
1.1  jtc internal cleanup of various kinds.
1.1  jtc
1.1  jtc New in alpha2.3:  Split change list out of README, and moved flags notes
1.1  jtc into Makefile.  Macro-ized the name of regex(7) in regex(3), since it has
1.1  jtc to change for 4.4BSD.  Cleanup work in engine.c, and some new regression
1.1  jtc tests to catch tricky cases thereof.
1.1  jtc
1.1  jtc New in alpha2.2:  Out-of-date manpages updated.  Regerror() acquires two
1.1  jtc small extensions -- REG_ITOA and REG_ATOI -- which avoid debugging kludges
1.1  jtc in my own test program and might be useful to others for similar purposes.
1.1  jtc The regression test will now compile (and run) without REDEBUG.  The
1.1  jtc BRE \$ bug is fixed.  Most uses of "uchar" are gone; it's all chars now.
1.1  jtc Char/uchar parameters are now written int/unsigned, to avoid possible
1.1  jtc portability problems with unpromoted parameters.  Some unsigned casts have
1.1  jtc been introduced to minimize portability problems with shifting into sign
1.1  jtc bits.
1.1  jtc
1.1  jtc New in alpha2.1:  Lots of little stuff, cleanup and fixes.  The one big
1.1  jtc thing is that regex.h is now generated, using mkh, rather than being
1.1  jtc supplied in the distribution; due to circularities in dependencies,
1.1  jtc you have to build regex.h explicitly by "make h".  The two known bugs
1.1  jtc have been fixed (and the regression test now checks for them), as has a
1.1  jtc problem with assertions not being suppressed in the absence of REDEBUG.
1.1  jtc No performance work yet.
1.1  jtc
1.1  jtc New in alpha2:  Backslash-anything is an ordinary character, not an
1.1  jtc error (except, of course, for the handful of backslashed metacharacters
1.1  jtc in BREs), which should reduce script breakage.  The regression test
1.1  jtc checks *where* null strings are supposed to match, and has generally
1.1  jtc been tightened up somewhat.  Small bug fixes in parameter passing (not
1.1  jtc harmful, but technically errors) and some other areas.  Debugging
1.1  jtc invoked by defining REDEBUG rather than not defining NDEBUG.
1.1  jtc
1.1  jtc New in alpha+3:  full prototyping for internal routines, using a little
1.1  jtc helper program, mkh, which extracts prototypes given in stylized comments.
1.1  jtc More minor cleanup.  Buglet fix:  it's CHAR_BIT, not CHAR_BITS.  Simple
1.1  jtc pre-screening of input when a literal string is known to be part of the
1.1  jtc RE; this does wonders for performance.
1.1  jtc
1.1  jtc New in alpha+2:  minor bits of cleanup.  Notably, the number "32" for the
1.1  jtc word width isn't hardwired into regexec.c any more, the public header
1.1  jtc file prototypes the functions if __STDC__ is defined, and some small typos
1.1  jtc in the manpages have been fixed.
1.1  jtc
1.1  jtc New in alpha+1:  improvements to the manual pages, and an important
1.1  jtc extension, the REG_STARTEND option to regexec().
