# OTP-27.0.1

## Improvements and New Features

- Bump ex_doc version to v0.34.1 and fix copyright in published docs to have
  correct year.

  Own Id: OTP-19095
  Related Id(s): PR-8507

# compiler-8.5.1

The compiler-8.5.1 application can be applied independently of other
applications on a full OTP 27 installation.

## Fixed Bugs and Malfunctions

- One of the compiler's optimization passes would get very slow when compiling
  certain modules. The compiler will now automatically disable that pass for
  input that would trigger the slowdown.

  Own Id: OTP-19131
  Related Id(s): PR-8567

- Fix `+deterministic` to work properly with documentation attributes.

# edoc-1.3.1

The edoc-1.3.1 application can be applied independently of other applications on
a full OTP 27 installation.

## Fixed Bugs and Malfunctions

- Fix broken makefile dependency when building HTML documentation.

# erts-15.0.1

The erts-15.0.1 application can be applied independently of other applications
on a full OTP 27 installation.

## Fixed Bugs and Malfunctions

- In rare circumstances the JIT could do an unsafe in-place update of a tuple.

- When a port command crashed in the inet driver during gen_tcp:send/2, a
  monitor `'DOWN'` message could be left lingering in the caller's mailbox. This
  has now been fixed.

  Own Id: OTP-19121
  Related Id(s): GH-8484

- `'DOWN'` messages originating from a monitored port, contained the atom
  `process` instead of the atom `port` as the third element when the exit reason
  was not an immediate term.

  Own Id: OTP-19123
  Related Id(s): GH-8484, PR-8546

- Fix so that the options to enable Transparent Huge Page alignment of the
  Erlang VM executable are only applied to the Erlang VM and not other native
  programs such as `erlc` and `dialyzer`. This bug was introduced in Erlang/OTP
  27.0.

  Own Id: OTP-19137
  Related Id(s): GH-8574

- When *no time warp mode* was enabled, a smaller Erlang monotonic time could
  be read than a previously read time, i.e., breaking the monotonic property.
  The runtime system will abort when detecting an issue like this since OTP
  24.3.4.17 and OTP 25.0.

  Up until OTP 25 _no time warp mode_ is the default. As of OTP 26 [*multi time
  warp mode*] is the default.

- When calling `trace:function(Session, _, true, meta)` the meta tracer was
  incorrectly set to be the calling process. Now it's set to the session tracer
  as expected.

# kernel-10.0.1

The kernel-10.0.1 application can be applied independently of other applications
on a full OTP 27 installation.

## Improvements and New Features

- Polish the `logger` documentation.

# public_key-1.16.1

The public_key-1.16.1 application can be applied independently of other
applications on a full OTP 27 installation.

## Fixed Bugs and Malfunctions

- Fix bug in dnsName constraint check, could cause valid cert to be considered
  bad during path validation.

# ssh-5.2.1

The ssh-5.2.1 application can be applied independently of other applications on
a full OTP 27 installation.

## Fixed Bugs and Malfunctions

- With this change, race condition between connection closing and automatic
  window adjustment is fixed.

# ssl-11.2.1

The ssl-11.2.1 application can be applied independently of other applications on
a full OTP 27 installation.

## Fixed Bugs and Malfunctions

- Check for TLS-1.3 support should check minimum requirements.

  Own Id: OTP-19094
  Related Id(s): GH-8489

- If both TLS-1.3 and TLS-1.2 is supported and TLS-1.2 negotiated convert
  TLS-1.3 ECDSA schemes to TLS-1.2 hash and signature pairs for increased
  interoperability.

  Own Id: OTP-19107
  Related Id(s): GH-8376

- TLS-1.3 negotiation now uses SNI based options correctly instead of ignoring
  them.

  Own Id: OTP-19140

## Improvements and New Features

- Make it easier to distinguish between a invalid signature and unsupported
  signature.

  Own Id: OTP-19091

- Enhance ALERT logs to help understand what causes the alert.

  Own Id: OTP-19092
  Related Id(s): GH-8482

- When the default value for signature_algs is used, default the
  signature_algs_cert to the default value + rsa_pkcs1_sha1 to allow this
  algorithms for certificates but not for the TLS protocol. This is for better
  interoperability. If signature_algs is set explicitly signature_algs_cert must
  also be set explicitly if they should be different.

# stdlib-6.0.1

The stdlib-6.0.1 application can be applied independently of other applications
on a full OTP 27 installation.

## Fixed Bugs and Malfunctions

- Fix so that missing `-doc({file, File})` files only result in a warning and
  not an error.

  Own Id: OTP-19099
  Related Id(s): PR-8542

- Fixed `json` bugs, json:encode_key_value_list/2 did not generate arrays
  and json:decode/3 did not invoke the user callback for `0`.
