## Important Changes ## ### 1.6.0 ### `geoipupdate` is removed from the GeoIP C library. Please use the seperate tool [geoipupdate](https://github.com/maxmind/geoipupdate) to download your subscriptions or our free databases. ### 1.5.0 ### Geoipupdate may be used to download our free databases. Put this into the config file /usr/local/etc/GeoIP.conf to download the free GeoLite databases GeoLiteCountry, GeoLiteCity and GeoLiteASNum ``` LicenseKey 000000000000 UserId 999999 ProductIds 506 533 517 ``` Free users should create symlinks for the GeoIP databases. For example: ``` cd /usr/local/share/GeoIP ln -s GeoLiteCity.dat GeoIPCity.dat ln -s GeoLiteCountry.dat GeoIPCountry.dat ln -s GeoLiteASNum.dat GeoIPASNum.dat ``` The lookup functions are thread safe. ### 1.3.6 ### As of version 1.3.6, the GeoIP C library is thread safe, as long as `GEOIP_CHECK_CACHE` is not used. ### 1.3.0 ### The GeoIP Region database is no longer a pointer but an in-structure array so test the first byte of region == 0 rather than testing if the region pointer is `NULL`. ### 1.1.0 ### As of GeoIP 1.1.0 the GeoIP_country_xxx_by_xxx functions return NULL if a country can not be found. It previously returned `--` or `N/A`. To avoid segmentation faults, check the return value for `NULL`.
