- When the `line_coverage` option was used, exceptions could show the wrong line
for where the exception was raised.

- The `line_coverage` option would be ignored if given in a `compile()`
attribute within a module.

Related Id(s): GH-8942, PR-8970
- A segment matching a float in a binary generator will now skip any invalid
float (such as a NaN) and continue matching the rest of the binary. Before
this correction, the comprehension would stop as soon as an invalid float was
encountered.
Example:
1> BadFloat = <<-1:64>>.
<<"ÿÿÿÿÿÿÿÿ">>
2> [X || <<X:64/float>> <= <<0.0/float,BadFloat/binary,42.0/float>>].
[0.0,42.0]

# debugger-5.5
The debugger-5.5 application can be applied independently of other applications
on a full OTP 27 installation.
## Fixed Bugs and Malfunctions
- Defining a fun in the shell using the syntax `fun Name/Arity` would fail. This
has been corrected so that the following now works:
1> F = fun is_atom/1.
#Fun.erl.42.18682967>
> F(a).
true
3> Id = fun id/1.
#Fun.erl.42.18682967>
4> Id(42).
** exception error: undefined shell command id/1
5> id(I) -> I.
ok
6> Id(42).
42
The Debugger has also been corrected to correctly handle this syntax for a
BIF.

# eldap-1.2.14
The eldap-1.2.14 application can be applied independently of other applications
on a full OTP 27 installation.

options in `eldap` could cause dialyzer warnings in user code referring to
`eldap` specs.

# erts-15.2
The erts-15.2 application can be applied independently of other applications on
a full OTP 27 installation.
## Fixed Bugs and Malfunctions
- gen_sctp:peeloff/2 has been fixed to inherit socket options to the peeled
off socket more like gen_tcp:accept/1, for example the options `tos` or
`tclass`.
When setting SCTP options that are unsupported on the platform, some should be
silently ignored, but a bug caused the option parsing to derail so the options
after could bail out and cause an error instead. This has been fixed.
Own Id: OTP-19225
Related Id(s): PR-8789
- Fixed a bug where Erlang would corrupt the terminal settings if stdin was a
TTY but stdout was not.
Own Id: OTP-19232
Related Id(s): GH-8487, PR-8794
- Fixed a bug in the non-JIT VM when loading a NIF over a function that is

existed since OTP-27.0, where multiple trace sessions were introduced.
Own Id: OTP-19248

construction instructions crashed the emulator on AArch64.

and perf.
Own Id: OTP-19362
Related Id(s): PR-9003
## Improvements and New Features
- Improved documentation of timers.
Own Id: OTP-19360
Related Id(s): ERIERL-1149, PR-9062
- The label for a process can now be retrieved also using
`process_info(Pid, label)` in addition to proc_lib:get_label/1.
This new option is useful when one wants to retrieve more than one process
info item. For example:
process_info(Pid, [label,registered_name])

`HttpOption {timeout, Timeout}`.
Own Id: OTP-19221
Related Id(s): ERIERL-1091, PR-8788, PR-8801
- Fixed a bug where calling httpc:set_options/2 when one of keys: _ipfamily_ or
_unix_socket_, was not present, would cause the other value to get overriden
by the default value. The validation of these options was also improved.
Own Id: OTP-19379
Related Id(s): GH-8829, PR-8878
## Improvements and New Features

- Fixed deadlock on `code_server`. Multiple calls loading the same module with
an `on_load` function loading call would create a deadlock.
