Extended error information for failing BIF calls as proposed in EEP 54 has been implemented.
When a BIF call from the Erlang shell fails, more information about which argument or arguments that were in error will be printed. The same extended error information will by proc_lib, common_test, and qlc when BIF calls fail.
For applications that wish to provide the same extended error information, there are new functions erl_error:format_exception/3 and erl_error:format_exception/4.
There is a new error/3 BIF that allows applications or libraries to provide extended error information in the same way for their own exceptions.

The process alias feature as outlined by EEP 53 has been introduced. It is introduced in order to provide a lightweight mechanism that can prevent late replies after timeout or connection loss. For more information, see EEP 53 and the documentation of the new alias/1 BIF and the new options to the monitor/3 BIF.
The call operation in the framework used by gen_server, gen_statem, and gen_event has been updated to utilize alias in order to prevent late responses. The gen_statem behavior still use a proxy process in the distributed case, since it has always prevented late replies and aliases wont work against pre OTP 24 nodes. The proxy process can be removed in OTP 26.
The alias feature also made it possible to introduce new functions similar to the erpc:receive_response() function in the gen behaviors, so the new functions gen_server:receive_response(), gen_statem:receive_response(), gen_event:receive_response() have also been introduced.

*** POTENTIAL INCOMPATIBILITY ***
Compiler warnings and errors now include column numbers in addition to line numbers.
When a compiler message is emitted, the source line is printed along with a marker (a ^ character) that indicates the column position of the issue. The option 'brief' removes the printout of the source line.
The compiler option {error_location, line | column} has been added. The default value is column. Besides adding column numbers to compilation warnings and errors, the option also determines whether column numbers are included in abstract code. If tools stop working, setting the environment variable ERL_COMPILER_OPTIONS can help (include {error_location, line}).
The compiler will now call the function PT:parse_transform_info/0 in parse transforms (if it exists). It can be used by parse transforms to signal that they can only handle line numbers in abstract code.

The BeamAsm JIT-compiler has been added to Erlang/OTP. The JIT-compiler is enabled by default on most x86 64-bit platforms that have a C++ compiler that can compile C++17. To verify that a JIT enabled emulator is running you can use erlang:system_info(emu_flavor).
For more information see the internal documentation of BeamAsm in erts.

*** POTENTIAL INCOMPATIBILITY ***
EDoc, the Erlang documentation engine, hits version 1.0 with this release, which means a few changes.
EDoc is now capable of emitting EEP-48 doc chunks. This means that, with some configuration, community projects can now provide documentation for shell_docs the same way that OTP libraries did since OTP 23.0.
The @spec and @type EDoc tags have been deprecated. These are not supported with the new chunk-generating doclet and layout. Moreover, previously when there was a redundant @spec tag and -spec attribute defined for the same function, the @spec tag would take precedence. Now, the -spec attribute takes precedence and is more important. The same is true for redundant @type tags and -type attributes. Warnings are now emitted when such redundant entries are found.
The ?NO_APP macro in edoc_doclet.hrl has been deprecated. Use the atom no_app instead.
See the Doc chunks chapter in the Edoc User's Guide for more details.

Generators in list and binary comprehensions will now raise a {bad_generator,Generator} exception if the generator has an incorrect type (instead of raising an ad-hoc badarg or badarih exception). Similarly, when a filter does not evaluate to a boolean, a {bad_filter,Filter} exception will be raised. Some minor bugs in the compilation of binary comprehensions have also been fixed.

Some compiler warnings, such as the warning for an expression whose result is ignored, could not be suppressed by assigning to a variable beginning with '_', but only by assigning to the anonymous variable ('_'). This has now been changed so that any warning that can be suppressed by assigning to the anonymous variable can also be suppressed by assigning to a variable beginning with '_'.

Potential Incompatibilities #
- OTP-15107
-
Time-outs in gen_statem with relative time 0 did not behave quite according to the intended model. This has now been corrected.
The correction introduces a small potential incompatibility e.g when combining a state time-out with inserted events, and the inserted event does a state change in the state with the time-out. Before this correction the state time-out could be delivered even after the second state change, but now it is guaranteed that a state time-out is only delivered in the state it was started for, even in this corner case.

The experimental new socket API has been further developed. Some backwards incompatible changes with respect to OTP 23 have been made.
The control message format has been changed so a decoded value is now in the 'value' field instead of in the 'data' field. The 'data' field now always contains binary data.
Some type names have been changed regarding message headers and control message headers.
socket:bind/2 now returns plain ok instead of {ok, Port} which was only relevant for the inet and inet6 address families and often not interesting. To find out which port was chosen use socket:sockname/1.

- Related Id(s):
- PR-2989
The behaviour for gen_tcp:connect/3,4 has been changed to not per default bind to an address, which allows the network stack to delay the address and port selection to when the remote address is known. This allows better port re-use, and thus enables far more outgoing connections, since the ephemeral port range no longer has to be a hard limit.
There is a theoretical possibility that this behaviour change can affect the set of possible error values, or have other small implications on some platforms.

The RSA SHA1 sign/verify variants are disabled by default. That is, ssh-rsa is disabled by default as well as the SHA1 sign/verify with RSA keys from id_rsa and ssh_host_rsa_key. All SHA2 sign/verify are enabled by default.
The reason is that SHA1 is now considered easy to break.

Large parts of the configure script of crypto have been rewritten with various improvements and bug fixes. It is now better at finding usable OpenSSL libraries, but will in the following cases fail to detect OpenSSL libraries where it previously sometimes detected the libraries by chance:
-- OpenSSL installations with include directory and lib directory parts installed in different base directories. In order to detect such installations after this change, the user must explicitly specify the locations using the --with-ssl=<path> and the --with-ssl-incl=<path> configure command line arguments.
-- When building with old gcc compilers or other compilers on Debian derivatives with multiarch directories under the lib directory.

EDoc, the Erlang documentation engine, hits version 1.0 with this release, which means a few changes.
EDoc is now capable of emitting EEP-48 doc chunks. This means that, with some configuration, community projects can now provide documentation for shell_docs the same way that OTP libraries did since OTP 23.0.
The @spec and @type EDoc tags have been deprecated. These are not supported with the new chunk-generating doclet and layout. Moreover, previously when there was a redundant @spec tag and -spec attribute defined for the same function, the @spec tag would take precedence. Now, the -spec attribute takes precedence and is more important. The same is true for redundant @type tags and -type attributes. Warnings are now emitted when such redundant entries are found.
The ?NO_APP macro in edoc_doclet.hrl has been deprecated. Use the atom no_app instead.
See the Doc chunks chapter in the Edoc User's Guide for more details.

Remove warning text about the -- operation from documentation

Therefore, the warning in the documentation saying that the time complexity is proportional to length(A)*length(B) is incorrect and is no longer needed. Notice that Erlang/OTP 21 will no longer be supported when Erlang/OTP 24 gets released.

The configure scripts in crypto and erts now fail if a requested feature cannot be enabled.
Large parts of the configure script of crypto have been rewritten with various improvements and bug fixes. It is now better at finding usable OpenSSL libraries, but will in the following cases fail to detect OpenSSL libraries where it previously sometimes detected the libraries by chance:
-- OpenSSL installations with include directory and lib directory parts installed in different base directories. In order to detect such installations after this change, the user must explicitly specify the locations using the --with-ssl=<path> and the --with-ssl-incl=<path> configure command line arguments.
-- When building with old gcc compilers or other compilers on Debian derivatives with multiarch directories under the lib directory. In order to detect such installations after this change, the user must explicitly specify the multiarch directory name using the --with-ssl-lib-subdir=lib/<multiarch-dir> configure command line argument.

When a BIF call from the Erlang shell fails, more information about which argument or arguments that were in error will be printed. The same extended error information will by proc_lib, common_test, and qlc when BIF calls fail.
For applications that wish to provide the same extended error information, there are new functions erl_error:format_exception/3 and erl_error:format_exception/4.
There is a new error/3 BIF that allows applications or libraries to provide extended error information in the same way for their own exceptions.

*** HIGHLIGHT ***
The process alias feature as outlined by EEP 53 has been introduced. It is introduced in order to provide a lightweight mechanism that can prevent late replies after timeout or connection loss. For more information, see EEP 53 and the documentation of the new alias/1 BIF and the new options to the monitor/3 BIF.
The call operation in the framework used by gen_server, gen_statem, and gen_event has been updated to utilize alias in order to prevent late responses. The gen_statem behavior still use a proxy process in the distributed case, since it has always prevented late replies and aliases wont work against pre OTP 24 nodes. The proxy process can be removed in OTP 26.
The alias feature also made it possible to introduce new functions similar to the erpc:receive_response() function in the gen behaviors, so the new functions gen_server:receive_response(), gen_statem:receive_response(), gen_event:receive_response() have also been introduced.

The experimental new socket API has been further developed. Some backwards incompatible changes with respect to OTP 23 have been made.
The control message format has been changed so a decoded value is now in the 'value' field instead of in the 'data' field. The 'data' field now always contains binary data.
Some type names have been changed regarding message headers and control message headers.
socket:bind/2 now returns plain ok instead of {ok, Port} which was only relevant for the inet and inet6 address families and often not interesting. To find out which port was chosen use socket:sockname/1.

By default all ERTS internal memory allocators based on alloc_util will now use their own separate carrier pool for migration of carriers instead of using a node global carrier pool. This was the default behavior between OTP 17 and OTP 21, but changed to use a node global carrier pool as of OTP 22.0. Usage of the node global carrier pool proved troublesome since it had a tendency to spread long lived blocks into allocators with normally short lived blocks causing increased memory fragmentation. The node global carrier pool behavior as well as other behaviors can be configured using the +M<S>cp command line argument.

Extended error information for failing BIF calls as proposed in EEP 54 has been implemented.
When a BIF call from the Erlang shell fails, more information about which argument or arguments that were in error will be printed. The same extended error information will by proc_lib, common_test, and qlc when BIF calls fail.
For applications that wish to provide the same extended error information, there are new functions erl_error:format_exception/3 and erl_error:format_exception/4.
There is a new error/3 BIF that allows applications or libraries to provide extended error information in the same way for their own exceptions.

The process alias feature as outlined by EEP 53 has been introduced. It is introduced in order to provide a lightweight mechanism that can prevent late replies after timeout or connection loss. For more information, see EEP 53 and the documentation of the new alias/1 BIF and the new options to the monitor/3 BIF.
The call operation in the framework used by gen_server, gen_statem, and gen_event has been updated to utilize alias in order to prevent late responses. The gen_statem behavior still use a proxy process in the distributed case, since it has always prevented late replies and aliases wont work against pre OTP 24 nodes. The proxy process can be removed in OTP 26.
The alias feature also made it possible to introduce new functions similar to the erpc:receive_response() function in the gen behaviors, so the new functions gen_server:receive_response(), gen_statem:receive_response(), gen_event:receive_response() have also been introduced.

The experimental new socket API has been further developed. Some backwards incompatible changes with respect to OTP 23 have been made.
The control message format has been changed so a decoded value is now in the 'value' field instead of in the 'data' field. The 'data' field now always contains binary data.
Some type names have been changed regarding message headers and control message headers.
socket:bind/2 now returns plain ok instead of {ok, Port} which was only relevant for the inet and inet6 address families and often not interesting. To find out which port was chosen use socket:sockname/1.

The behaviour for gen_tcp:connect/3,4 has been changed to not per default bind to an address, which allows the network stack to delay the address and port selection to when the remote address is known.

Before this correction the state time-out could be delivered even after the second state change, but now it is guaranteed that a state time-out is only delivered in the state it was started for, even in this corner case.

The standard floating point printing algorithm used by the io and io_lib modules has been changed from the algorithm described in [1] to the Ryu algorithm [2]. This gives a significant speed improvement for the printing of most floating point numbers and a small memory consumption improvement.

For cover-compiled code, the error behaviour of list and binary comprehensions that used andalso/orelse in guards could be changed so that a filter that was supposed be evaluated in guard context was evaluated in body context. That is, there was a possibility that comprehensions that did not raise exceptions could raise exceptions when being run using cover.
