Based on a PR by Jussi Sallinen. 1.6.9 2016-01-11 - Fix a regression introduced in version 1.6.8, which caused GeoIP_database_info to erroneously return NULL. 1.6.8 2016-01-11 - Allow compilation on older systems by relaxing the autoconf and automake minimum versions. Thank you, Jose Rubio! - Avoid potential problems in multi-threaded environments by consistently using pread() rather than read(). - Fix various small issues reported by clang's static analyser. 1.6.7 2015-10-30 - Fixed a MSVC parser stack overflow when parsing `regionName.c` and `timeZone.c`. Fix by elliotlo. GitHub #64. - Updated region codes and timezones. - When using `GEOIP_MEMORY_CACHE` with an invalid database file, the search tree traversal could attempt to read memory outside of the memory allocated for the memory cache, resulting in a segmentation fault. A check was added to ensure that the traversal code does not try to read beyond the end of the file, whether in memory, memory mapped, or on disk. - Previously the return values from file reads were ignored. We now check these values to ensure that there were no errors. 1.6.6 2015-07-28 - Replaced usage of deprecated fileno, read, and lseek on Visual Studio 2005+ with their ISO C++ conformant replacements. - A warning about using a double as a float was fixed. - Fixed segfault when doing a lookup on an empty database. - Fixed a memcheck error from valgrind in the `_check_mtime` function. - Fixed `_check_mtime` to check the return value of `gettimeofday` rather than just assuming it worked. 1.6.5 2015-02-25 - A segmentation fault in `geoiplookup` was fixed when the utility was passed an invalid database. - Additional validation was added for validation of the size used in the creation of the index cache. - Changed the code to only look up country codes by using functions which ensure that we do not try to look past the end of an array. 1.6.4 2015-01-12 - Update Fips codes - Several issues with the MinGW build were fixed. - Use a constructor in pread.c to ensure the critical section is always initialized. - Added missing include of `io.h` on Windows. - Fixed `configure` warning that `'missing' script is too old or missing`. - Previously `nmake /f Makefile.vc clean` would fail on Windows. This was fixed. - Obsolete win32 and NetWare make files were removed. - Numerous documentation updates. 1.6.3 2014-10-29 - Added a GEOIP_SILENCE flag. Include this flag when calling GeoIP_open to prevent any messages from being written to stderr. - Mitigate a possible race condition when running under threads in the GeoIP_cleanup function. - Added some recommendations to the docs on using this library in a threaded application. - Fixed some bugs discovered by coverity, including failure to check some system call return values and making sure all strings are null-terminated. 1.6.2 2014-07-08 - Two files required for building on Win32 were missing from the 1.6.1 release. These files were added. There are no changes affecting other platforms. 1.6.1 2014-06-26 - Improve Win32 support - Update FIPS codes 1.6.0 2013-10-29 - Remove geoipupdate 1.5.2 2013-10-29 - Update region and time zones - Fix benchmark script - Remove autogenerated files ltmain.sh, man/geoip*.1 - Explain how to download free geolite databases in the README.md and GeoIP.conf.default - geoipupdate returns 1 on error 0 on success instead of the error code - README is replaced by README.md - Add support for OS X Mavericks 1.5.1 2013-05-14 - Update time_zone for Ontario, Canada - geoiplookup and geoiplookup6 exit code is 0 when user asked for help - Added -h option to geoiplookup6 - Do not load the database file if nodes and file size do not make sense. - Keep README and man pages in pure ascii. - It doesn't make sense to use GEOIP_INDEX_MODE with small databases like GEOIP_COUNTRY_EDITION. Instead of undefined behaviour we handle it silently as GEOIP_MEMORY_MODE - Update FIPS codes for Greece 1.5.0 2013-02-21 - Rename custom_directory to GeoIP_custom_directory. - Make sure the database match the requested type. This is helpful for Databases with the same default name and the general geoiplookup form (geoiplookup without a specific database) - apps/geoiplookup6.c use the ipnum instead of the hostname for lookups. - Use configure.ac instead of configure.in - Region lookup is a bit faster - Add pkg-config file - Updates required to build a Windows DLL under MinGW - Make API thread safe - geoiplookup's default charset is UTF8 -l change the charset back to iso8859-1 - geoipupdate skips \r otherwise it might be part of the last product_id - Update time zones - Update Region codes - Remove the unused CITYCONFIDENCE* database types - bootstrap rebuilds ltmain.sh - Update README.OSX for Lion - Change Macedonia to Macedonia, The Former Yugoslav Republic of - Add region_name to geoiplookup GEOIP_CITY_EDITION_REV1 - Add region_name to geoiplookup GEOIP_CITY_EDITION_REV0 - Add a --disable-data-files option. This allows you to build and install the library without having a data/GeoIP.dat file. This is useful when building the library from a checkout of the source tree, rather than a tarball - Add GEOIP_ACCURACYRADIUS_EDITION and GEOIP_ACCURACYRADIUS_EDITION_V6 - Add more database types GEOIP_COUNTRYCONF_EDITION, GEOIP_CITYCONF_EDITION, GEOIP_REGIONCONF_EDITION and GEOIP_POSTALCONF_EDITION - Fix default filenames for GEOIP_NETSPEED_EDITION_REV1 and GEOIP_NETSPEED_EDITION_REV1_V6
