If not in POSIX mode, changes to ENVIRON are reflected into + gawk's environment, affecting any programs run by system() + or for piped redirections. This can also affect built-in routines, such + as mktime(), which is typically influenced by the TZ environment variable. + +2. The series of numbers returned by rand() should now be "more + random" than previously. Gawk's rand() remains repeatable; you will + get the same series of numbers each time you call rand() repeatedly, + but this will be a different series than previously. + +3. The --pretty-print option no longer runs the program too. + +4. The igawk script and igawk.1 man page are no longer installed by + `make install'. They have been obsolete since gawk 4.0.0. + +5. Gawk now has a `intdiv()' function to perform integer division; this is + primarily useful for the -M option to avoid MPFR division when all + values involved are integers. + +6. Gawk can now be built with CMake. This is an alternative build + system for those who may want it; gawk is not going to switch off + use of the autotools anytime soon, if ever. + +7. Gawk now processes a maximum of two hexadecimal digits in \x + escape sequences inside strings. + +8. MirBSD is no longer supported. + +9. Pretty printing now preserves comments and places them into the + pretty-printed file. + +10. `make install' now installs shell startup files + $sysconfdir/profile.d/gawk.{csh,sh} containing shell functions to + manipulate the AWKPATH and AWKLIBPATH environment variables. On a Fedora + system, these files belong in /etc/profile.d, but the appropriate location + may be different on other platforms. + +11. Gawk now supports retryable I/O via PROCINFO[input-file, "RETRY"]; see + the manual. + +12. The API minor version has been increased to two; the get_file() + API provides access to open redirections. Also see the manual. + Changes from 4.1.1 to 4.1.2 --------------------------- |
