In the HTML version of the doc those spaces are necessary to separate
those words.

The module is not added in a function call inside a macro.

Currently, the external fun syntax "fun M:F/A" only supports
literals. That is, "fun lists:reverse/1" is allowed but not
"fun M:F/A".
In many real-life situations, some or all of M, F, A are
not known until run-time, and one is forced to either use
the undocumented erlang:make_fun/3 BIF or to use a
"tuple fun" (which is deprecated).
EEP-23 suggests that the parser (erl_parse) should immediately
transform "fun M:F/A" to "erlang:make_fun(M, F, A)". We have
not followed that approach in this implementation, because we
want the abstract code to mirror the source code as closely
as possible, and we also consider erlang:make_fun/3 to
be an implementation detail that we might want to remove in
the future.
Instead, we will change the abstract format for "fun M:F/A" (in a way
that is not backwards compatible), and while we are at it, we will
move the translation from "fun M:F/A" to "erlang:make_fun(M, F, A)"
from sys_pre_expand down to the v3_core pass. We will also update
the debugger and xref to use the new format.
We did consider making the abstract format backward compatible if
no variables were used in the fun, but decided against it. Keeping
it backward compatible would mean that there would be different
abstract formats for the no-variable and variable case, and tools
would have to handle both formats, probably forever.

These dependency files was once used when building the documentation,
but are no longer needed.

The two noncharacter code points 16#FFFE and 16#FFFF were not
allowed to be encoded or decoded using the unicode module or
bit syntax. That causes an inconsistency, since the noncharacters
16#FDD0 to 16#FDEF could be encoded/decoded.
There is two ways to fix that inconsistency.
We have chosen to allow 16#FFFE and 16#FFFF to be encoded and
decoded, because the noncharacters could be useful internally
within an application and it will make encoding and decoding
slightly faster.

"Its" is a possessive pronoun, "it's" is a contraction of
"it is".

The latest additions to the extension of Erlang used for describing
types and specifications have been documented. There are new compiler
attributes such as -opaque and -export_all as well as an alternative
syntax for subtype constraints ('::' instead of is_subtype/2).

Wrote and changed some tests in stdlib:erl_lint_SUITE
nowarn_bif_clash is obsoleted but will remove warnings and errors about bif
clashes. The recommended way is to use no_auto_import directives instead.
Hopefully erlang.erl is the only user in the world of nowarn_bif_clash.

* ta/nested-records:
Document R14 paren-less record access/update
Support nested record field access without parentheses
OTP-8597 ta/nested-records
Nested records can now be accessed without parenthesis. See the Reference
Manual for examples. (Thanks to YAMASHINA Hio and Tuncer Ayaz.)
|
|
Add a section to the reference manual describing the R14
change to not require parentheses when accessing or updating
fields in nested records.

is_boolean/1 was introduced in R10B, so this is a little
bit late...

An on_load function is supposed to return 'true' to indicate
that the module should be loaded, and 'false' if it should be
unloaded. But returning any other term, as well as causing an
exception, will also unload the module.
Since we don't like boolean values mixed with other values,
change the expected return value as follows:
* If 'ok' is returned, the module will remain loaded and become
callable.
* If any other value is returned (or an exception is generated),
the module will be unloaded. Also, if the returned value is
not an atom, send a warning message to the error_logger
(using error_logger:warning_msg/2).
The new interpretation of the return value means that an on_load
function can now directly return the return value from
erlang:load_nif/2.

NIF function prototypes in order to allow more than 3 function
arguments. Also an incompatible change in the return value of
erlang:load_nif/2. Added support for references, floats and term
comparison in NIFs. Read more in the documentation of erl_nif and
erlang:load_nif/2.

In the transition from SGML to XML (several releases ago),
bugs were introduced in the documentation, for instance
"\n" replaced by newlines. Correct those bugs.
Also correct double backslashes. They seem to have been introduced very
early in the development of OTP. According to Lars they "solved" a bug
in the generation of HTML &c. Now that standard tools are used instead
of docbuilder, the bug has become visible.
