System: OTP
Release: 28
Application: compiler-9.0.3, erts-16.1.2, kernel-10.4.2,
public_key-1.19, ssh-5.3.4, ssl-11.4.2,
syntax_tools-4.0.2
Predecessor: OTP 28.1.1
Check out the git tag OTP-28.2, 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.
# compiler-9.0.3
The compiler-9.0.3 application can be applied independently of other
applications on a full OTP 28 installation.
## Fixed Bugs and Malfunctions
- Fixed broken type inference for lists:mapfoldl/r.
Own Id: OTP-19845
Related Id(s): GH-10354, PR-10358
> #### Full runtime dependencies of compiler-9.0.3
>
> crypto-5.1, erts-13.0, kernel-8.4, stdlib-6.0
# erts-16.1.2
The erts-16.1.2 application can be applied independently of other applications
on a full OTP 28 installation.
## Fixed Bugs and Malfunctions
- Fixed a JIT bug that could miscompile equality tests on empty bitstrings.
Own Id: OTP-19846
Related Id(s): PR-10359
- The documentation building code produced warnings during the build, if none of
the applications were skipped. The warnings were resolved.
Own Id: OTP-19865
Related Id(s): ERIERL-1251, PR-10396
> #### Full runtime dependencies of erts-16.1.2
>
> kernel-9.0, sasl-3.3, stdlib-4.1
# kernel-10.4.2
The kernel-10.4.2 application can be applied independently of other applications
on a full OTP 28 installation.
## Fixed Bugs and Malfunctions
- Fixed a race condition when registering the standard error process.
Own Id: OTP-19832
Related Id(s): PR-10290
> #### Full runtime dependencies of kernel-10.4.2
>
> crypto-5.0, erts-15.2.5, sasl-3.0, stdlib-6.0
# public_key-1.19
Note! The public_key-1.19 application _cannot_ be applied independently of other
applications on an arbitrary OTP 28 installation.
On a full OTP 28 installation, also the following runtime
dependency has to be satisfied:
-- crypto-5.7 (first satisfied in OTP 28.1)
## Improvements and New Features
- Added support for the Public-Key Infrastructure Certificate Management
Protocol (PKICMP) ASN.1 specification.

> #### Full runtime dependencies of public_key-1.19
>
> asn1-5.0, crypto-5.7, erts-13.0, kernel-8.0, stdlib-4.0
# ssh-5.3.4
The ssh-5.3.4 application can be applied independently of other applications on
a full OTP 28 installation.
## Fixed Bugs and Malfunctions
- With this change user space buffers are used to limit ssh hello message size
instead of kernel buffers
Own Id: OTP-19839

# ssl-11.4.2
Note! The ssl-11.4.2 application _cannot_ be applied independently of other
applications on an arbitrary OTP 28 installation.
On a full OTP 28 installation, also the following runtime
dependencies have to be satisfied:
-- crypto-5.7 (first satisfied in OTP 28.1)
-- public_key-1.18.3 (first satisfied in OTP 28.1)
## Fixed Bugs and Malfunctions
- Graceful error handling added in negative test scenario.
Own Id: OTP-19813
Related Id(s): PR-10284
- Handle duplicate change_cipher_spec message with an unexpected message alert
instead of failing later in corrupted state.
Own Id: OTP-19818
Related Id(s): PR-10296
- Make sure TLS-1.3 protocol spec is followed, that is psk-hello extension is
guaranteed to be included as the last extension in the list of client hello
extensions and internal hello message truncation in handshake history is
handled correctly, the previous handling could cause interoperability issues.
Own Id: OTP-19825
Related Id(s): PR-10296
- If two certificate massages are sent to the server generate an unexpected
message alert for the second one.

# syntax_tools-4.0.2
The syntax_tools-4.0.2 application can be applied independently of other
applications on a full OTP 28 installation.
## Fixed Bugs and Malfunctions
- Annotate map comprehensions and generators
