Check out the git tag OTP-27.0.1, and build a full OTP system including documentation. Apply one or more applications from this build as patches to your installation using the 'otp_patch_apply' tool. For information on install requirements, see descriptions for each application version below.

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.

Own Id: OTP-19142
Related Id(s): GH-8579, PR-8585

crypto-5.1, erts-13.0, kernel-8.4, stdlib-6.0

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.

Own Id: OTP-19116

erts-11.0, inets-5.10, kernel-7.0, stdlib-4.0, syntax_tools-2.0, xmerl-1.3.7

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.

Own Id: OTP-19108
Related Id(s): PR-8539

• 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.

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.

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.
