-* Mon May 17 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
+* Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.19 (RPL/2)
+- preprocessor does not use sed anymore;
+- some workarounds have been written to not use buggy klibc SystemV IPCS.
+ABORT now works on eComStation;
+- sqlite is upgraded to 3.7.2;
+- bug is fixed in software interrupts. When both process have different PID,
+parent process was not interrupted if it is not group master process. To fix
+this bug, SIGINJECT signal is not sent by child process but by control thread
+in parent process;
+- minor bug is fixed in data injection (POKE) that does not work as expected
+when child process is protected by NRPROC.
+* Thu Aug 26 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.18 (RPL/2)
+- --enable-sysv-sems is added to configure script to use SystemV semaphores
+functions instead of POSIX functions. This function is disabled or forced on
+systems that does not provide correct POSIX or SysV semaphores subsystem;
+- a dirty but not quick patch is written to workaround broken siginfo
+structures. This patch has been successfully tested. It uses a segment of
+shared memory (SysV) and eleven semaphores (Posix or SysV) by process
+(Unix PID);
+- some OpenBSD's hacks are added;
+- broken siginfo->si_pid field is now checked by configure script;
+- SWI now sends SIGCONT to interrupted process to start interrupt without delay;
+- random generator is cloned by SPAWN;
+- in transliteration subroutine : '\r' is added after all '\n' in OS/2 port;
+- getaddrinfo is hardcoded when host system does not provide getaddrinfo
+or freeaddrinfo;
+- RPL/2 can now use SystemV semaphores when POSIX semaphores are unavailable;
+- major bug is fixed in CHR intrinsic when obtained character is not printable;
+- Lapack is upgraded to 3.2.2;
+- OS/2 (eComStation 2.0 with EMX 0.9d) support is added;
+- TOKENIZE is now able to convert escape sequences;
+- ATPOKE and CLRATPOKE new intrinsics are added;
+- --enable-full-static configure flag is added. With this flag, mysql and
+postgresql libraries are statically linked in rpl executable;
+- units Makefile is modified to avoid readline and ncurses usages;
+- sqlite is upgraded to 3.7.0.1;
+- units is upgraded to 1.88;
+- another major bug is fixed in the same variable creation subroutine.
+Level 0 and 1 variables adresses were swapped when a global variable masked
+a name of RPL/2 routine;
+- major bug is fixed in global variable creation subroutine. When a global
+variable was created and when a local variable existed with the same name,
+computed address of global variable was wrong;
+- src/Makefile.am is modified to avoid a bug on several systems. libptmalloc3
+is forced in front of all libraries.
+* Tue Jul 13 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.17 (RPL/2)
+- BACKTRACE intrinsic is added;
+- major bug is fixed in SELECT/DEFAULT/END conditional structure. Only occurs
+when this structure is included in IFERR/THEN/END structure and when an error is
+caught;
+- major bug is fixed in analyse() subroutine. When evaluation() returned error
+in a compiled program, analyse() caught this error twice and randomly aborted
+with a segmentation error;
+- TRIM and TOKENIZE replace both '\n' and '\t' by regular spaces;
+- ATEXIT subroutine begins with an implicit CSTOP to avoid multiple stop
+signals;
+- memory leak is fixed in ROW+. It only occurs when a row is added to an empty
+matrix.
+* Thu Jun 24 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.16 (RPL/2)
+- minor bug is fixed in evaluation() subroutine. With this patch, same program
+returns same result with or without -p flag;
+- ncurses 5.7 is upgraded to 20100619;
+- openssl is upgraded to 1.0.0a;
+- interrupt stacks are now FIFO instead of LIFO;
+- debug memory allocation subroutines are improved to run in multithreaded
+programs;
+- some memory leaks are fixed in process management (SPAWN and DETACH);
+- version verification is added to shared objects;
+- -D_GNU_SOURCE is added to ptmalloc3 makefile to avoid a major bug on 64 bits
+linux (false mremap() prototype);
+- major bug is fixed in rpliconv. getc() returns an int, not a unsigned char.
+* Sun May 23 2010 BERTRAND Joël <rpl@systella.fr> rpl-4.0.15 (RPL/2)
+- all '-' are replaced by '_' in random generator list;
 - minor memory leak is fixed in OPEN intrinsic (socket);
 - major bug is fixed in IFERR structure. Only occurs in compiled program;
 - major bug is fixed in copie_objet() and liberation(). Only concerns
