For embedded applications that can call the 'main()' function multiple
times, they need to have any statically (globally) defined variables
reset to their default values.
./autogen.sh and ./configure no longer need to be run prior to running
make for Contiki, LwIP or RIOT from the appropriate examples sub-directory.
scripts/fix_version.sh now handles updating coap.h for the different
LIBCOAP_ and PACKAGE_ definitions.
Tidy up the general proxy logic by moving common functionality
into libcoap.
New functions coap_proxy_forward_request(), coap_proxy_forward_response()
and coap_proxy_is_supported() added.
New --enable-proxy-code support added to configure.
New ENABLE_PROXY_CODE support added to CMakeLists.txt.
Support for common shared connection to next hop.
Support for round-robin balancing across multiple next hops.
Create new options coap_uri_into_optlist(), coap_path_into_optlist() and
coap_query_into_optlist() to be used instead of coap_uri_into_options(),
coap_split_path() and coap_split_query() functions so the requirement
for a scratch buffer is not needed.
Getting the minimum size for a scratch buffer is not straight forward and
potential for unexpected boundary condition errors to occurif too small.
Correct parsing and stripping out of "%2E%2E" ("..") and "%2E" (".")
path segments. ".." now removes the previous segment (if it exists).
Update documentation and unit testcases.
Update examples to use new options.
Move requirements for client to determine how to set up the SNI for
PSK/PKI encrypted communications down into libcoap. The client just
needs to indicate the host to connect to in the client_sni field of
coap_dtls_cpsk_t or coap_dtls_pki_t.
New internal function coap_sanitize_client_sni() makes sure that
the SNI sent follows RFC 6066. As per
https://datatracker.ietf.org/doc/html/rfc6066#section-3
Literal IPv4 and IPv6 addresses are not permitted in "HostName".
all IPv4 and IPv6 addresses are dropped for the SNI, and so no SNI is
sent. DNS hostnames will get transmitted as the SNI.
Optional compile time thread safe code supported.
Locking is done at the coap_context_t level, and if enabled is primarily
done coap_threadsafe.c and coap_threadsafe_internal.h.
coap_threadsafe_internal.h causes coap_X() to get mapped to coap_X_locked()
throughout the libcoap library code with the exception of coap_threadsafe.c
if thread safe is enabled.
coap_debug.h: Support logging level set to _COAP_LOG_EMERG
coap_pdu.h: handle small ints
coap_pdu_internal.h: handle small ints
coap_session_internal.h: handle small ints
coap_uthash_internal.h: handle small ints
coap_block.c: Handle small ints
coap_debug.c: Fix use of vsnprintf() and vfprintf()
coap_pdu.c: Handle small ints
coap_tinydtls.c: Handle small ints
coap_uri.c: Fix alignment issue in coap_new_uri()
uncrustify run on RIOT examples to conform to RIOT's coding standards/
This then makes sure that all things libcoap are properly initialized
before use, and coders realize they need to do this.
Note: coap_new_context() continues to make sure that coap_startup()
is invoked if not done previously, but this may be too late.

Move some existing header inline code into source files.
Update coap_resolve_address_info() to remove need for client based app
code to have to understand IPv4/IPv6 code.
Remove IPv4/IPv6 specific code from examples code.
This means that apps need to have no knowledge of what IP support is available.
Updates coap_uri_into_options() and coap_resolve_address_info()
which have only been recently added to develop branch and are not in any
previous release.
