maps:put with existing key and identical value was not
41+
optimized as a no-op correctly if having the same 32-bit
42+
hash as another key in the map. In practice very rare and
43+
harmless.</p>

A process optimized for parallel signal delivery could
62+
under some circumstances lose wakeup information. That
63+
is, the processes was not woken up to take care of the
64+
signal, so the signal would not be taken care of until
65+
the process was woken by another signal. Only processes
66+
configured with <seeerl
67+
marker="erlang#process_flag_message_queue_data"><c>message_queue_data</c></seeerl>
68+
set to <c>off_heap</c> utilize this optimization.</p>

Delivery time of message signals to a process not
113+
executing any <c>receive</c> expressions could become
114+
very long, potentially infinite. For example, a process
115+
checking for messages using <c>process_info(self(),
116+
message_queue_len)</c> or <c>process_info(self(),
117+
messages)</c> and avoiding to execute a <c>receive</c>
118+
expression matching on messages could be very slow in
119+
detecting new messages. Note that you are still
120+
discouraged from using <c>process_info()</c> this way. A
121+
process that wants to check if there are messages
122+
available to handle should execute a <c>receive</c>
123+
expression matching on messages.</p>

<p>On AArch64 (ARM64), when calculating both the quotient
129+
and remainder with a divisor begin a power two, the
130+
remainder could be incorrectly calculated.</p>

Fix bug causing "magic" references in a <c>compressed</c>
137+
ETS table to not keep the referred object alive. The
138+
symptom would be the referred object being garbage
139+
collected prematurely and the reference appearing stale,
140+
not referring to anything. Examples of such magically
141+
referred objects are <c>atomics</c> and NIF resources.</p>

<p>A BEAM file usually contains a chunk with the tag
161+
"Type" containing type information that can be used by
162+
the JIT. The <c>beam_lib:strip/1</c> takes care to
163+
preserve that chunk, but a build/release tool that does
164+
customized stripping could accidentally remove the chunk.
165+
Loading a BEAM file without the "Type" chunk could cause
166+
incorrect behavior of the loaded code.</p>

<p>In Erlang/OTP 27, by default escripts will be compiled
213+
before being executed. That means that the

<c>compiler</c> application must be installed. It is

the directive <c>-mode(interpret).</c> to the escript
