It records user -visible -changes between releases of flex. +flex NEWS -See the file COPYING for copying conditions. +* Noteworthy changes in release 2.6.4 (2017-05-06) [stable] + +** build + +*** The indent target now knows about flex's new (as of 2.6.0) + layout. The indent rules it would apply are not correct and do + need to be fixed. + +*** The files included in the flex distribution are now built by the + version of flex that is included in the distribution. + +*** The configure script has a better idea of which headers are + required to build flex. It will also error when missing functions + are detected. + +*** We have lowered the versions of automake and gettext that + configure.ac lists as required for building flex. In autogen.sh, + we now check for how to call libtoolize and use what we find in + the rest of the script. + +*** Since files in lib/ are picked up as needed by src/, we no longer + generate a Makefile for that directory. + +*** Flex can be cross compiled. + +** documentation + +*** Some typos were removed from the manual. + +** scanner + +*** Some minor performance enhancements. + +*** We honor user defined yy_* macros again. We are also more careful + to not leak macro definitions into header files. + +*** A number of portability fixes were introduced so building flex is + more reliable on more platforms. Additionally, outdated function + calls were removed. + +*** When building the flex executable itself, %# comments from + flex.skl are removed when generating the C source code array. This + reduces the size of flex. + +** test suite + +*** All scripts in the test suite are now run by $(SHELL) and the + needed portability fixes have been included. + +*** Test suite dependencies are handled much better. This only matters + if you are actively developing flex or its test suite. + +*** Tests that depend on platform dependent features now properly skip + when those platforms are not present. + +*** When running "make check", you can now pas V=0 to silence more of + the build. This is useful when you're less connncerned about the + details of building and linking the test programs themselves. + +* Noteworthy changes in release 2.6.3 (2016-12-30) [stable] + +** scanner + +*** several bug fixes resolved problems introduced in recent flex + versions regarding processing of comments, literals and various + quoting scenarios. + +*** If the path to m4 was sufficiently long, a buffer overflow could + occur. This has been resolved. The fix also removes dependence on + the constant PATH_MAX. + +** build + +*** A new configure option --disable-bootstrap changes the behavior of + the build system when building flex. The default + "--enable-bootstrap" behavior is to build flex, then to use that + flex to build flex again. With --disable-bootstrap, the scanner is + simply built by sedding the scanner source. This is friendlier to + cross compilation. + +*** The compatibility functions in lib/ are no longer built as a + library. Instead, they are built as $(LIBOBJ) objects. This is + simpler and friendlier to cross compilation. + +*** It is now possible to build flex without building the accompanying + libfl. This is friendlier to cross compilation. See the + --disable-libfl option to configure. Resolves #99. + +*** the PIC version of libfl was not correctly built. It is no longer + included in the build/installation targets of flex since it was + unused. + +*** the distributed man page is only rebuilt when the relevant source + files change or when the binary doesn't exist. In particular, this + is friendlier to cross compilation. Resolves #108 + +** test + +*** the shell scripts in the test suite are more portable across different shell implementations. + +* version 2.6.2 released 2016-10-24 + +** flex internals + +*** a segfalt involving yyrestart(NULL) has been fixed + +*** flex should now handle quoting when mixed with m4 processing correctly + +*** flex handles `[[' and `]]' correctly + +*** flex no longer generates non-ANSI code + +*** more compilation warnings were squashed in generated scanners + +*** prevented a buffer overflow that could occur when input buffers were the exact wrong size + +** test suite + +*** input filenames on MSWindows are now calculated correctly + +*** general code cleanups in a number of tests now make the test suite compile much more cleanly + +** build system + +*** the xz archive has been replaced with an lzip archive + +*** a new option to configure --enable-warnings to encapsulate passing + of warning-related flags which is useful in testing flex -* flex version 2.5.39 +*** make indent now works for out of source builds + +*** Portability warnings when generating Makefile.in files are now suppressed; they were just noise and the use of GNU extensions in Makefile.{am,in,} was intentional and well known. + +** bugs + +*** resolved gh#67 + +** new sv translation from the translation project + +* version 2.6.1 released 2016-03-01 + +** flex resources + +*** The flex project is now hosted at github. Consider this a "period of transition". In particular, you should start at https://github.com/westes/flex for the flex codebase, issue tracking and pull requests. + +*** New releases of flex are to be found at https://github.com/westes/flex/releases. + +** flex internals + +*** Flex now uses more modern and more standard names for variable types. There's more work to be done on that front yet, though. + +*** A number of compiler warnings have been remedied. + +*** Line directives should now work as expected and be absent when that is expected. + +** test suite + +*** When running the test suite, c++ files are compiled with the c++ header inside the flex distribution, rather than relying on the build system's flex header , which might not be installed yet or which might be out of date with respect to what flex tests expect. + +*** Some portability fixes in the test suite such as opening files for reading in binary mode + +** Building flex + +*** The file src/scan.c asdistributed with flex source is now built with the current version of flex. Occasionally this had to be done manually to pick up new flex features. It's now just a part of flex's build system. + +*** The pdf version of the manual is no longer distributed with flex, although if you have the texinfo package installed, you can still build it. + +*** lots of general build system cleanup + +*** the build system tries a bit harder to find libtoolize and texi2dvi. + +*** When help2man and texi2dvi are missing, the error messages are now much more helpful. + +** bug fixes + +*** resolved github issues #53, #54, #55, #61. + +*** Resolved sf bugs #128, #129, #155, #160, #184, #187, #195. + +* version 2.6.0 released 2015-11-17 + +** User Visible Changes + +*** C++ scanners now use references instead of pointers. See the manual for details. + +*** A number of compiler warnings were addressed, so flex generated scanners should be quieter under compiler warning scenarios. + +*** Allow error reporting routines to accept varying number of arguments + +*** Removed deprecated 'register' storage class specifier + +*** Changeed output formats from octal to hexadecimal + +*** check limits before using array index cclp; resolves sf-166 + +*** Suppress clang warning about empty @param paragraph; resolves sf#158 + +*** Fixed malloc/realloc replacement, resolves sf bug#151. + +*** Adjusted buffer sizes on ia64. + +*** various documentation and code clean up fixes: resolves sf bugs #167, #168, among other patches. + +** Flex Internals + +*** flex is now organized into subdirectories. This keeps the tree neater at the top level and puts like things near each other and unlike things away from each other. + +*** The test suite has been reorganized and is now run with the parallel test suite harness from automake. + +*** Cleaned up the automake parts of the build system to better reflect what automake does on its own. Also added a call to libtoolize in autogen.sh because autoreconf gets confused without a prior run of libtoolize. + +*** po/Makefile now includes a rule to fetch the latest translations from the translation project.
