## Highlights

SSH:

* The cipher 'chacha20-poly1305@openssh.com' is now  supported if OpenSSL 1.1.1 or higher is used as cryptolib.

* The key exchange methods 'curve25519-sha256@libssh.org', 'curve25519-sha256' and 'curve448-sha512' are implemented. 
They all depends on that OpenSSL 1.1.1 or higher used as cryptolib.

Crypto:

* Typing in crypto and public_key applications are reworked and corrected.
* New chapter on Algorithm details in the User's guide

ERTS, Kernel:

* The socket options recvtos, recvttl, recvtclass and pktoptions have been implemented in the socket modules. Se documentation in gen_tcp, gen_udp and inet modules for more info!

# OTP 24 Release Candidate 2

This is the second of three planned release candidates before the OTP 24 release.
The intention with this release is to get feedback from our users. All feedback is welcome, even if it is only to say that it works for you.

We encourage users to try it out and give us feedback either by creating an issue here https://github.com/erlang/otp/issues
 or by posting to the mailing list erlang-questions@erlang.org.

Erlang/OTP 24 is a new major release with new features, improvements as well as a few incompatibilities. Some of the new
features are highlighted below.

## Highlights rc2

### compiler
- The compiler will now inline funs that are used only once immediately after their definition.

### erts, kernel, stdlib
- hex encoding and decoding functions added in the binary module

#### There is as usual a number of bug fixes and improvements detailed in the readme.

## Highlights rc1
### erts, kernel, stdlib

- The BeamAsm JIT-compiler has been added to Erlang/OTP and will give a significant performance boost for many applications.
  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)`.

- A compatibility adaptor for `gen_tcp` to use the new socket API has been implemented (`gen_tcp_socket`).
- Extended error information for failing BIF calls as proposed in EEP 54 has been implemented.
- Process aliases as outlined by EEP 53 has been introduced.

### compiler

- Compiler warnings and errors now include column numbers in addition to line numbers.
- Variables bound between the keywords `'try'` and `'of'` can now be used in the clauses following the `'of'` keyword
  (that is, in the success case when no exception was raised).

### ftp

- Add support for FTPES (explicit FTP over TLS).

### ssl

- Support for the "early data" feature for TLS 1.3 servers and clients.
- Make TLS handshakes in Erlang distribution concurrent.


### wx

- The application has been completely rewritten in order
  to use wxWidgets version 3 as its base.
- Added support for wxWebView.

### edoc

- 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.

               When using the DNS resolver option
               servfail_retry_timeout it did not honour the overall
               call time-out in e.g inet_res:getbyname/3. This
               misbehaviour has now been fixed. Also, the
               servfail_retry_timeout behaviour has been improved to
               only be enforced for servers that gives a servfail
               answer.

               execution on scheduler threads to be delayed until
               other similar work appeared. Beside delaying various
               cleanup of internal data structures also the following
               could be delayed:

               -- Termination of a distribution controller process

               -- Gathering of memory allocator information using the

               allocator_sizes, _})

               -- A call to erlang:trace_delivered()

               The bug existed on runtime systems running on all types
               of hardware except for x86/x86_64.

               Related Id(s): ERL-1458, OTP-16239

               Avoid that upgrade (from TCP to TLS) servers starts
               multiple session cache handlers for the same server.
               This applies to Erlang distribution over TLS servers.


  OTP-17174    Application(s): ssl
               Related Id(s): ERIERL-597

               Legacy cipher suites defined before TLS-1.2 (but still
               supported) should be possible to use in TLS-1.2. They
               where accidentally excluded for available cipher suites
               for TLS-1.2 in OTP-23.2.2.

               although TLS-1.2 will still be default.

               Integers outside of the range [-(1 bsl 32) - 1, (1 bsl
               32) -1] were previously intended to be printed in an
               internal bignum format by ei_print_term() and
               ei_s_print_term(). Unfortunately the implementation has
               been buggy since OTP R13B02 and since then produced
               results with random content which also could crash the
               calling program.

               This fix replaces the printing of the internal format
               with printing in hexadecimal form and extend the range
               for printing in decimal form. Currently integers in the
               range [-(1 bsl 64), (1 bsl 64)] are printed in decimal
               form and integers outside of this range in Erlang
               hexadecimal form.

Erlang/OTP 23.2 is the second maintenance patch release for OTP 23, with mostly bug fixes as well as a few improvements.

A few of the changes and highlights are:

### SSL

Handle extraneous certs in certificate chains as well as chains that are incomplete but can be reconstructed or unordered chains. The cert and certfile options will now accept a list of certificates so that the user may specify the chain explicitly.

### Potential incompatibility 
#### stdlib

Improved the API and documentation of the uri_string module. Added a new chapter to the Users Guide about Uniform Resource Identifiers and their handling with the new API. Added two new API functions: uri_string:allowed_characters/0 and uri_string:percent_decode/1.

This change has been marked as potentially incompatible as uri_string:normalize/2 used to decode percent-encoded character triplets that corresponded to characters not in the reserved set. After this change, uri_string:normalize/2 will only decode those percent-encoded triplets that correspond to characters in the unreserved set (ALPHA / DIGIT / "-" / "." / "_" / "~").


A full list of bug fixes and improvements in the [readme](https://erlang.org/download/OTP-23.2.README).

               inet:setopts([{active,once}]) wakes up IO polling
               thread unnecessarily, leading to lock contention and
               visibly higher CPU utilization.


  OTP-16870    Application(s): erts

               Two bugs in the ERTS internal thread wakeup
               functionality have been fixed. These bugs mainly hit
               when all threads in the system tried to go to sleep.
               When the bugs were triggered, certain operations were
               delayed until a thread woke up due to some other
               reason. Most important operations effected were code
               loading, persistent term updates, and memory
               deallocation.


  OTP-16874    Application(s): erts
               Related Id(s): ERL-1356, PR-2763

               Fixed bug in ets:select_replace/2 on compressed tables

  OTP-16892    Application(s): erts

               When compiling Erlang/OTP on macOS using Xcode 12, the
               performance of the BEAM interpreter would be degraded.


 --- Improvements and New Features ---

  OTP-16856    Application(s): erts

               As of OTP 22, the allocator specific memory carrier
               pools were replaced by a node global carrier pool. This
               unfortunately caused substantial memory fragmentation
               in some cases due to long lived data being spread into
               carriers used by allocators mainly handling short lived
               data.

               A new command line argument +M<S>cp has been introduced
               with which one can enable the old behavior as well as
               configuring other behaviors for the carrier pools. In
               order to configure the old behavior, with allocator
               specific carrier pools for all allocators, pass +Mucp :
               (including the colon character) as a command line
               argument to erl when starting the Erlang system.

               The default configuration for carrier pools will be
               changed to +Mucp : some time in the future, but not in
               this patch.

               The configuration parameter
               memsup_improved_system_memory_data has been introduced.
               It can be used to modify the result returned by
               memsup:get_system_memory_data(). For more information
               see the memsup documentation.

               Note that the configuration parameter is intended to be
               removed in OTP 24 and the modified result is intended
               to be used as of OTP 24.

Erlang/OTP 23.1 is the first maintenance patch release for OTP 23, with mostly bug fixes as well as a few improvements.

### Vulnerability fix

A vulnerability in the httpd module (inets application) regarding directory traversal that was introduced in OTP 22.3.1 and corrected in OTP 22.3.4.6. It was also introduced in OTP 23.0 and corrected in OTP 23.1 The vulnerability is registered as CVE-2020-25623.
The vulnerability is only exposed if the http server (httpd) in the inets application is used. The vulnerability makes it possible to read arbitrary files which the Erlang system has read access to with for example a specially prepared http request.

### General build issues

* Adjust /bin/sh to /system/bin/sh in scripts when installing on Android.
* Changes in build system to make it build for macOS 11.0 with Apple Silicon. Also corrected execution of match specs to work on Apple Silicon.

A full list of bug fixes and improvements in the [readme](http://erlang.org/download/OTP-23.1.README).

               When a temporary child of a simple_one_for_one
               supervisor died, the internal state of the supervisor
               would be corrupted in a way that would cause the

OTP 23.0.1

OTP-23.0.0-bundle.tar.gz

OTP-23.0.0-bundle.txt

## OTP 23

Erlang/OTP 23 is a new major release with new features, improvements as well as a few incompatibilities.


### Potential Incompatibilities
- **SSL**:
    - Support for SSL 3.0 is completely removed.
    - TLS 1.3 is added to the list of default supported versions.   
- `erl_interface`: Removed the deprecated parts of `erl_interface` (`erl_interface.h` and essentially all C functions with prefix `erl_`).
- The deprecated `erlang:get_stacktrace/0` BIF now returns an empty list instead of a stacktrace. `erlang:get_stacktrace/0` is scheduled for removal in OTP 24.

### Improvements and new features
- **ssh**: 
    - OpenSSH 6.5 introduced a new file representation of keys called `openssh-key-v1`. This is now supported with the exception of handling encrypted keys.
    - Algorithm configuration could now be done in a .config file. This is useful for example to enable an algorithm that is disabled by default without need to change the code.  
- **SSL**:
    - Support for the middlebox compatibility mode makes the TLS 1.3 handshake look more like a TLS 1.2 handshake and increases the chance of successfully establishing TLS 1.3 connections through legacy middleboxes.
    - Add support for key exchange with Edward curves and PSS-RSA padding in signature verification

- The possibility to run Erlang distribution without relying on EPMD has been extended. To achieve this a couple of new options to the inet distribution has been added.
    - `-dist_listen false` Setup the distribution channel, but do not listen for incoming connection.
    - `-erl_epmd_port Port`  Configure a default port that the built-in EPMD client should return.
- A first EXPERIMENTAL `socket` backend to
 `gen_tcp` and `inet` has been implemented. `gen_udp` and `gen_sctp` will follow. 
  Putting `{inet_backend, socket}` as first option to `listen()` or `connect()` makes it easy to try this for  existing code

- A new module `erpc` in kernel which implements an enhanced subset of the operations provided by the `rpc` module. Enhanced in the sense that it makes it possible to distinguish between returned value, raised exceptions and other errors. `erpc` also has better performance and scalability than the original `rpc` implementation. This by utilizing the newly introduced `spawn_request()` BIF. Also the `rpc` module benefits from these improvements by utilizing `erpc` when possible.
- Scalability and performance Improvements plus new functionality regarding distributed spawn operations. 
- In binary matching, the size of the segment to be matched is now allowed to be a guard expression (EEP-52)
- When matching with maps the keys can now be guard expressions (EEP-52).
- ssh: support for TCP/IP port forwarding, a.k.a tunnelling a.k.a as tcp-forward/direct-tcp is implemented. In the OpenSSH client, this corresponds to the options -L and -R.
- Allow underscores in numeric literals to improve readability. Examples: `123_456_789`, `16#1234_ABCD`.
- New functions in the shell for displaying documentation for Erlang modules, functions and types. The
  functions are:
    - `h/1,2,3` -- Print the documentation for a `Module:Function/Arity`.
    - `ht/1,2,3` -- Print the type documentation for a `Module:Type/Arity`.
  The embedded documentation is created as docchunks (EEP 48) when building the Erlang/OTP documentation.
- **kernel**: The module `pg` with a new implementation of distributed named process groups is introduced. The old module `pg2` is deprecated and scheduled for removal in OTP 24.
- Our tool chain for building the Windows packages is upgraded with new C++ compiler, Java compiler, OpenSSL libraries and wxWidgets versions. We are now using WSL (the Linux Subsystem for Windows when building) which makes it easier to handle the build environment.
