If a match on 0.0 specifically is desired (distinct from -0.0), the warning can be suppressed by writing +0.0 instead. The arithmetic comparison operators are unaffected, including arithmetic equality (==).

The call is_record(A, a, 0) would crash the compiler when used in a function body. When used in a guard the compiler would emit incorrect code that would accept {a> as a record.

OTP-18647 Application(s): erts Related Id(s): PR-7595 A process optimized for parallel signal delivery could under some circumstances lose wakeup information. That is, the processes was not woken up to take care of the signal, so the signal would not be taken care of until the process was woken by another signal. Only processes configured with message_queue_data set to off_heap utilize this optimization.

OTP-18706 Application(s): erts Related Id(s): ERIERL-979, GH-7413, PR-7595 Delivery time of message signals to a process not executing any receive expressions could become very long, potentially infinite. For example, a process checking for messages using process_info(self(), message_queue_len) or process_info(self(), messages) and avoiding to execute a receive expression matching on messages could be very slow in detecting new messages. Note that you are still discouraged from using process_info() this way. A process that wants to check if there are messages available to handle should execute a receive expression matching on messages. OTP-18724 Application(s): erts Related Id(s): GH-7566, PR-7567 On AArch64 (ARM64), when calculating both the quotient and remainder with a divisor begin a power two, the remainder could be incorrectly calculated.

The symptom would be the referred object being garbage collected prematurely and the reference appearing stale, not referring to anything. Examples of such magically referred objects are atomics and NIF resources. OTP-18733 Application(s): erts Related Id(s): GH-7292 Matching out short bitstrings with a fixed size not divisible by 8 could could lead to the runtime system terminating with an "Overrun heap and stack" error. OTP-18737 Application(s): erts Related Id(s): PR-7595 A constant flow of incoming non-message signals could prevent a process needing to execute dirty from doing so. OTP-18745 Application(s): erts Related Id(s): GH-7492, PR-7616 A BEAM file usually contains a chunk with the tag "Type" containing type information that can be used by the JIT. The beam_lib:strip/1 takes care to preserve that chunk, but a build/release tool that does customized stripping could accidentally remove the chunk. Loading a BEAM file without the "Type" chunk could cause incorrect behavior of the loaded code. OTP-18747 Application(s): erts, kernel Related Id(s): GH-7605 gen_udp:recv/* for Unix Domain Socket in binary mode and passive mode has been fixed to not crash. OTP-18752 Application(s): erts Related Id(s): PR-7633 The cleanup operation of not yet delivered signals to a terminated process yielded excessively.

OTP-18638 Application(s): erts In Erlang/OTP 27, by default escripts will be compiled before being executed. That means that the compiler application must be installed. It is possible to force the escript to be interpreted by adding the directive -mode(interpret). to the escript file. In Erlang/OTP 28, support for interpreting an escript will be removed. OTP-18660 Application(s): erts, kernel Add basic support for socket ioctl on Windows. OTP-18661 Application(s): erts Related Id(s): PR-6112 Removed erts/etc/darwin/Info.plist, as it is no longer necessary after macos 10.12 OTP-18686 Application(s): erts, kernel Add support for (Windows) socket option exclusiveaddruse.

OTP-18704 Application(s): inets Related Id(s): ERIERL-962, OTP-18688, PR-7513 With this change, error report generated by httpd during connection setup contains socket type information. OTP-18708 Application(s): inets Related Id(s): ERIERL-962, OTP-18688 Stop and restart of the httpd server in the Inets application has been refactored to a more synchronous and OTP supervisor friendly approach.

OTP-18700 Application(s): ssl Related Id(s): GH-7507 The API function `ssl:recv/3` has been tightened to disallow negative length, which has never been documented to work, but was passed through and caused strange errors. OTP-18712 Application(s): ssl Related Id(s): GH-7431 When a client initiated renegotiation was rejected and the client socket was in active mode the expected error message to the controlling process was not sent. --- Improvements and New Features --- OTP-18631 Application(s): ssl Add some guidance for signature algorithms configuration in ssl applications users guide.

The call is_record(A, a, 0) would crash the compiler when used in a function body. When used in a guard the compiler would emit incorrect code that would accept {a> as a record. OTP-18614 Application(s): stdlib Related Id(s): GH-7162, PR-7237 Fix bug in ets:tab2file that could make it fail if another Erlang process created the same file at the same time. OTP-18616 Application(s): stdlib Related Id(s): GH-7258 An {else_clause,Value} exception will now be reported nicely in the shell. OTP-18627 Application(s): stdlib Related Id(s): PR-7072 Correct return value for error case, so that it matches the documented and intended return value {error, {already_started, pid()} when local registered names are used. OTP-18633 Application(s): stdlib sys:get_state/1,2 and sys:replace_state/2,3 has been corrected to handle a state named error as a state name, not as a failed system callback. For the standard server behaviours this was an issue only for gen_statem (and gen_fsm) when the state name was error, and for gen_server if the complete state was {error,_}. OTP-18655 Application(s): stdlib Related Id(s): GH-6460, PR-7208 Multiple problems were fixed in filelib:safe_relative_path/2. If its second argument was a path that contained symbolic links, an incorrect result patch could be returned. Also, paths were sometimes falsely considered unsafe. OTP-18675 Application(s): kernel, stdlib Related Id(s): GH-7459, PR-7473 Fix deadlock when erl.exe is used as part of a pipe on Windows and trying to set the encoding of the standard_io device. OTP-18676 Application(s): common_test, erl_docgen, erts, kernel, stdlib Related Id(s): GH-7459, PR-7473 Expanded the documentation about how to use the standard_io, standard_error and user I/O devices. Added the types io:standard_io/0, io:standard:error/0 and io:user/0. OTP-18683 Application(s): stdlib Related Id(s): PR-7502 Fix h/2,3 to properly render multi-clause documentation. OTP-18759 Application(s): stdlib Related Id(s): GH-7606 Timers created by timer:apply_after/4, apply_interval/4, and apply_repeatedly/4 would silently fail to do the apply if it was not possible to spawn a process when the timer expired. This has now been corrected, and if the spawn fails, the system will be taken down producing a crash dump. OTP-18763 Application(s): stdlib Related Id(s): GH-7655 When an Erlang source file lacked a module definition, there would be a spurious "module name must not be empty" diagnostic for each spec in the file. --- Improvements and New Features --- OTP-18679 Application(s): stdlib Related Id(s): ERIERL-965 The argument descriptions for option types in argparse have been made less ambiguous. OTP-18690 Application(s): stdlib Related Id(s): GH-7510, PR-7511 Clarified the documentation of normal shutdown reason on gen_server:call/2,3 OTP-18696 Application(s): stdlib *** POTENTIAL INCOMPATIBILITY *** Pattern matching and equivalence (=:=, =/=) comparisons on 0.0 will now raise a warning, as it will no longer be considered equivalent to -0.0 in OTP 27. If a match on 0.0 specifically is desired (distinct from -0.0), the warning can be suppressed by writing +0.0 instead. The arithmetic comparison operators are unaffected, including arithmetic equality (==). OTP-18705 Application(s): stdlib Related Id(s): GH-6339, GH-7524, OTP-18471, PR-6843 The semantics of the gen_{server,statem,event} behaviour's synchronous start behaviour introduced in OTP-26.0 with OTP-18471, has been clarified in the documentation. OTP-18736 Application(s): stdlib Related Id(s): PR-7564 Added functionality to set a custom multiline prompt. OTP-18746 Application(s): stdlib Related Id(s): PR-7313, PR-7456 *** HIGHLIGHT *** *** POTENTIAL INCOMPATIBILITY *** A warning for (accidental use of) Triple-Quoted Strings has been implemented as per EEP 64.
