installation using the 'otp_patch_apply' tool. For information on install
requirements, see descriptions for each application version below.
# erts-15.2.7
The erts-15.2.7 application can be applied independently of other applications
on a full OTP 27 installation.
## Fixed Bugs and Malfunctions

>
> kernel-9.0, sasl-3.3, stdlib-4.1
# kernel-10.2.7
Note! The kernel-10.2.7 application _cannot_ be applied independently of other
applications on an arbitrary OTP 27 installation.
On a full OTP 27 installation, also the following runtime
dependency has to be satisfied:
-- erts-15.2.5 (first satisfied in OTP 27.3.2)
## Fixed Bugs and Malfunctions
- With this change, disk_log will not crash when using chunk_step/3 after log
size was decreased.
Own Id: OTP-19605
Related Id(s): GH-9720, PR-9765
- With this change, disk_log will not run into infinite loop when using
chunk/2,3 after log size was decreased.

> crypto-5.0, erts-15.2.5, sasl-3.0, stdlib-6.0
# ssh-5.2.11
The ssh-5.2.11 application can be applied independently of other applications on
a full OTP 27 installation.
## Fixed Bugs and Malfunctions
- Fix KEX strict implementation according to draft-miller-sshm-strict-kex-01
document.
Own Id: OTP-19625
Related Id(s): CVE-2025-46712

> stdlib-5.0, stdlib-6.0
# xmerl-2.1.3
The xmerl-2.1.3 application can be applied independently of other applications
on a full OTP 27 installation.
## Improvements and New Features
- A new option to discard whitespace before the `xml` tag when reading from a
stream has been added to the Xmerl SAX parser.
- **`{discard_ws_before_xml_document, Boolean}`** - Discard whitespace before
`xml` tag instead of returning a fatal error if set to `true` (`false` is
default)
