-Changes in version 2.1.12-stable (05 Jul 2020) 
- 
- This release contains mostly bug fixes (I decided not to port some features 
- that can be ported even without ABI breakage, if you cannot find feature that 
- you are interested in, please give us a note!) 
- 
- Since 2.1.12 libevent will use github actions as main CI, since 
- it recommends itself better then travis/appveyor (and had been removed from 
- upstream). 
- 
- Look carefully at "slightly touches the behaviour" section. 
- 
- Below you will find some of changes (this list has been cleaned up from the 
- patches that touches only tests and similar): 
- 
- CI: 
-  o Backport github actions to 2.1 (be3acd7c Azat Khuzhin) 
-  o Merge branch 'event_rpcgen.py-cleanup' (f0ded5f3, 48e04887 Enji Cooper) 
-  o Add API/ABI checker (using LVC) (709210d4, 2af1f6cc yuangongji) 
- 
- test: 
-  o tinytest: support timeout on Windows (794e8f75 yuangongji) 
-  o Merge branch 'osx-clock' (e85afbe3 Azat Khuzhin) 
-  o test-ratelim: calculate timers bias (for slow CPUs) to avoid false-positive (8ad26d0b Azat Khuzhin) 
- 
- fixes: 
-  o buffer: do not pass NULL to memcpy() from evbuffer_pullup() (5b063049 Azat Khuzhin) 
-  o http: fix undefined-shift in EVUTIL_IS*_ helpers (6b8d02a7 Azat Khuzhin) 
-  o Check error code of evhttp_add_header_internal() in evhttp_parse_query_impl() (97e28f09 Azat Khuzhin) 
-  o http: fix EVHTTP_CON_AUTOFREE in case of timeout (and some else) (1be25938 Azat Khuzhin) 
-  o evdns: Add additional validation for values of dns options (c2972453 ayuseleznev) 
-  o There is typo in GetAdaptersAddresses windows library. It should be iphlpapi.dll (891adda9 Aleksandr-Melnikov) 
-  o Merge branch 'EV_CLOSED-and-EV_ET-fixes' (db2efdf5 Azat Khuzhin) 
-  o Fix memory corruption in EV_CLOSURE_EVENT_FINALIZE with debug enabled (8ccd8f56 Jan Kasiak) 
-  o increase segment refcnt only if evbuffer_add_file_segment() succeeds (30662a3c yuangongji) 
-  o evdns: fix a crash when evdns_base with waiting requests is freed (6f8e0e97 ayuseleznev) 
-  o event_base_once: fix potential null pointer threat (2e9ceb16 chenguolong) 
-  o http: do not assume body for CONNECT (1b42270b Azat Khuzhin) 
-  o evbuffer_add_file: fix freeing of segment in the error path (5f017bde Azat Khuzhin) 
-  o Fix checking return value of the evdns_base_resolv_conf_parse() (fc51bf2c Azat Khuzhin) 
-  o Merge branch 'fix-signal-leak' (poll/select now needs reinit) (1c9cc07b Azat Khuzhin) 
- 
- improvements: 
-  o evutil_time: improve evutil_gettimeofday on Windows (a8219143 Nick Grifka) 
-  o Support EV_CLOSED on linux for poll(2) (2530e7c6 Azat Khuzhin) 
-  o Parse IPv6 scope IDs. (f602211f Philip Homburg) 
-  o evutil_time: Implements usleep() using wait funtion on Windows (d42240d1 yuangongji) 
-  o evutil_time: detect and use _gmtime64_s()/_gmtime64() (f4a6152c yuangongji) 
- 
- slightly touches the behaviour: 
-  o bufferevent: allow setting priority on socket and openssl type (4dd3acdd Nicolas J. Bouliane) 
-  o Fix EV_CLOSED detection/reporting (epoll only) (1df324d4 Azat Khuzhin) (XXX) 
-  o Revert "Warn if forked from the event loop during event_reinit()" (71f5c0d3 Azat Khuzhin) 
- 
- samples: 
-  o https-client: load certificates from the system cert store on Windows (e9478640 yuangongji) 
- 
- build fixes: 
-  o Do not use sysctl.h on linux (it had been deprecated) (d2871a37 Azat Khuzhin)
