The kerberos5 library Heimdal is one of three GSS libraries curl support.
It has a memory leak triggered by the new test in #18917 and the project
seems mostly abandoned.
Drop support and steer users to the MIT krb5 or GNU GSS libraries.

The implementation was incomplete and lesser than the other backends. No
one ever reported a bug or requested enhancements for this, indicating
that this backend was never used.
Closes#18700
These libraries do not support TLS 1.3 and have been marked for removal
for over a year. We want to help users select a TLS dependency that is
future-proof and reliable, and not supporting TLS 1.3 in 2025 does not
infer confidence. Users who build libcurl are likely to be served better
and get something more future-proof with a TLS library that supports
1.3.
Closes#16677
- replace ß (scharfes S) with links.
- replace § (section sign) with links.
- replace 🙏 emoji with `🙏`.
Supported by GitHub, Forgejo/Gitea and most likely GitLab.
- docs/libcurl/curl_mprintf.md: replace Unicode ± with `{+|-}`.
- docs/CIPHERS.md: URL encode Unicode in URLs.
- lib1560: use hex encoding in `räksmörgås.se`.
- unit1307: use hex encoding in `Lindmätarv`.
- drop LATIN SMALL LETTER A WITH ACUTE exception.
No longer appears in tests.
This leaves the single character exception: `ö`
And file exceptions holding contributor names.

With this change, the argument passed to the CURLOPT_FOLLOWLOCATION
option is now instead a "mode" instead of just a boolean. Documentation
is extended to describe the two new modes.
Test 1571 to 1581 verify.
Closes#16473
mbedtls is picky when a mbedtls_ssl_write) was previously blocked. It
requires to be called with the same amount of bytes again, or it will
lose bytes, e.g. reporting all was sent but they were not. Remember the
blocked length and use that when set.

- Move all Windows unicode issues into the single "bug", as they are all
at least semi-related
- Removed ancient issues that are not relevant anymore
Closes#14775
Use these words and casing more consistently across text, comments and
one curl tool output:
AIX, ALPN, ANSI, BSD, Cygwin, Darwin, FreeBSD, GitHub, HP-UX, Linux,
macOS, MS-DOS, MSYS, MinGW, NTLM, POSIX, Solaris, UNIX, Unix, Unicode,
WINE, WebDAV, Win32, winbind, WinIDN, Windows, Windows CE, Winsock.
Mostly OS names and a few more.
Also a couple of other minor text fixups.
Closes#14360
These have lingered in the issue tracker for a long time without action.
We don't expect any fixes in the near term either. Move them to the
KNOWN_BUGS document.

- cmake: populate for dependencies.
- autotools: populate for dependencies.
(including mbedtls, though the script does not detect
mbedtls through pkgconfig. mbedtls 3.6.0 now supports it.)
Skip dealing with gssapi in this patch.

This adds connection shutdown infrastructure and first use for FTP. FTP
data connections, when not encountering an error, are now shut down in a
blocking way with a 2sec timeout.
- add cfilter `Curl_cft_shutdown` callback
- keep a shutdown start timestamp and timeout at connectdata
- provide shutdown timeout default and member in
`data->set.shutdowntimeout`.
- provide methods for starting, interrogating and clearing
shutdown timers
- provide `Curl_conn_shutdown_blocking()` to shutdown the
`sockindex` filter chain in a blocking way. Use that in FTP.
- add `Curl_conn_cf_poll()` to wait for socket events during
shutdown of a connection filter chain.
This gets the monitoring sockets and events via the filters
"adjust_pollset()" methods. This gives correct behaviour when
shutting down a TLS connection through a HTTP/2 proxy.
- Implement shutdown for all socket filters
- for HTTP/2 and h2 proxying to send GOAWAY
- for TLS backends to the best of their capabilities
- for tcp socket filter to make a final, nonblocking
receive to avoid unwanted RST states
- add shutdown forwarding to happy eyeballers and
https connect ballers when applicable.
Closes#13904
Letting CMake figure out where libraries are located gives you full
paths. When generating libcurl.pc and curl-config, getting libraries as
full paths is unusual when one expects to get a list of -l<libname>.
To meet expectations, an effort is made to convert the full paths into
-l<libname>, possibly with -L<libdir> before it.
