+  During cross-compilation, CARES_RANDOM_FILE may not be able to be appropriately

+  the port number is in range instead of a blind cast.

+  fix memory leak in ares_send (#511)
+  
+  When the condition channel->nservers < 1 holds, the function returns
+  prematurely, without deallocating query->tcpbuf. We rearrange the
+  check to be done prior to the allocations, avoiding the memory
+  leak. In this way, we also avoid unnecessary allocations if
+  channel->nservers < 1 holds.

+  Watcom Portability Improvements (#509)
+  
+  - Modify the Watcom Makefile for the source code reorganization (#352)
+  - Add *.map files into .gitignore
+  - Fix build errors with Watcom's builtin Windows SDK (which is rather
+    outdated). It's smart enough to understand Windows Vista, but doesn't
+    have PMIB_UNICASTIPADDRESS_TABLE or MIB_IPFORWARD_ROW2.
+  
+  It may be possible to use a different Windows SDK with the Watcom
+  compiler, such as the most recent Windows 10 SDK. Alternatively the SDK
+  in OpenWatcom 2.0 (which is in development) should fix this.
+  
+  I have no problems testing this Makefile prior to releases, just give me
+  a ping.
+  
+  Tested with Windows Vista, Windows 7, and Windows 10 using 'adig',
+  'acountry', and 'ahost'. This also seems to work on Windows XP, though
+  this is likely due to the compiler in use.

-c-ares version 1.19.0
+c-ares version 1.19.1
 
-This is a feature and bugfix release.  It addresses a couple of new feature
-requests as well as a couple of bug fixes.
+This is a security and bugfix release.
 
-Security:
- o Low. Stack overflow in ares_set_sortlist() which is used during c-ares
-   initialization and typically provided by an administrator and not an
-   end user. [24]
+A special thanks goes out to the Open Source Technology Improvement Fund
+(https://ostif.org) for sponsoring a security audit of c-ares performed by X41
+(https://x41-dsec.de).
 
-Changes:
- o Windows: Drop support for XP and derivatives which greatly cleans up
-   initialization code. [3]
- o Add ARES_OPT_HOSTS_FILE similar to ARES_OPT_RESOLVCONF for specifying a
-   custom hosts file location. [10]
- o Add vcpkg installation instructions [13]
+Security:
+ o CVE-2023-32067. High. 0-byte UDP payload causes Denial of Service [12]
+ o CVE-2023-31147. Moderate. Insufficient randomness in generation of DNS
+   query IDs [13]
+ o CVE-2023-31130. Moderate. Buffer Underwrite in ares_inet_net_pton() [14]
+ o CVE-2023-31124. Low. AutoTools does not set CARES_RANDOM_FILE during cross
+   compilation [15]
 
 Bug fixes:
- o Fix cross-compilation from Windows to Linux due to CPACK logic. [1]
- o Fix memory leak in reading /etc/hosts when using localhost fallback. [2]
- o Fix chain building c-ares when libresolv is already included by another
-   project [4]
- o File lookup should not immediately abort as there may be other tries due to
-   search criteria.
- o Asterisks should be allowed in host validation as CNAMEs may reference
-   wildcard domains [5]
- o AutoTools build system referenced bad STDC_HEADERS macro [6]
- o Even if one address class returns a failure for ares_getaddrinfo() we should
-   still return the results we have
- o CMake Windows: DLLs did not include resource file to include versions [7] [8]
- o CMake: Guard target creation in exported config [9]
- o Fix ares_getaddrinfo() numerical address resolution with AF_UNSPEC [11]
- o Apple: fix libresolv configured query times. [12]
- o Fix tools and help information [14] [15]
- o Various documentation fixes and cleanups [16] [22] [25]
- o Add include guards to ares_data.h [17]
- o c-ares could try to exceed maximum number of iovec entries supported by
-   system [18]
- o CMake package config generation allow for absolute install paths [19]
- o Intel compiler fixes [20]
- o ares_strsplit bugs [21] [23]
- o The RFC6761 6.3 states localhost subdomains must be offline too. [26]
+ o Fix uninitialized memory warning in test [1]
+ o Turn off IPV6_V6ONLY on Windows to allow IPv4-mapped IPv6 addresses [2]
+ o ares_getaddrinfo() should allow a port of 0 [3]
+ o Fix memory leak in ares_send() on error [4]
+ o Fix comment style in ares_data.h [5]
+ o Remove unneeded ifdef for Windows [6]
+ o Fix typo in ares_init_options.3 [7]
+ o Re-add support for Watcom compiler [8]
+ o Sync ax_pthread.m4 with upstream [9]
+ o Windows: Invalid stack variable used out of scope for HOSTS path [10]
+ o Sync ax_cxx_compile_stdcxx_11.m4 with upstream to fix uclibc support [11]
