Erlang/OTP 28.0-rc2 is the second release candidate of three before the OTP 28.0 release.
The intention with this release is to get feedback from our users. All feedback is welcome, even if it is only to say that it works for you.
We encourage users to try it out and give us feedback either by creating an issue at https://github.com/erlang/otp/issues or by posting to Erlang Forums.
Erlang/OTP 28 is a new major release with new features, improvements as well as a few incompatibilities. Some of the new features are highlighted below.
Many thanks to all contributors!
Highlights for RC2
Functionality making it possible for processes to enable reception of priority messages has been introduced in accordance with EEP 76.
Highlights for RC1
New language features
Comprehensions have been extended with “zip generators” allowing multiple generators to be run in parallel. For example, [A+B || A <- [1,2,3] && B <- [4,5,6]] will produce [5,7,9].
Generators in comprehensions can now be strict, meaning that if the generator pattern does not match, an exception will be raised instead of silently ignore the value that didn’t match.
For certain types of errors, the compiler can now suggest corrections. For example, when attempting to use variable A that is not defined but A0 is, the compiler could emit the following message: variable 'A' is unbound, did you mean 'A0'?
The size of an atom in the Erlang source code was limited to 255 bytes in previous releases, meaning that an atom containing only emojis could contain only 63 emojis. While atoms are still only allowed to contain 255 characters, the number of bytes is no longer limited.
The warn_deprecated_catch option enables warnings for use of old-style catch expressions on the form catch Expr instead of the modern try … catch … end.
Provided that the map argument for a maps:put/3 call is known to the compiler to be a map, the compiler will replace such calls with the corresponding update using the map syntax.
Some BIFs with side-effects (such as binary_to_atom/1) are optimized in try … catch in the same way as guard BIFs in order to gain performance.
The compiler’s alias analysis pass is now both faster and less conservative, allowing optimizations of records and binary construction to be applied in more cases.
ERTS
The trace:system/3 function has been added. It has a similar interface as erlang:system_monitor/2 but it also supports trace sessions.
os:set_signal/2 now supports setting handlers for the SIGWINCH, SIGCONT, and SIGINFO signals.
The two new BIFs erlang:processes_iterator/0 and erlang:process_next/1 make it possible to iterate over the process table in a way that scales better than erlang:processes/0.
Shell and terminal
The erl -noshell mode has been updated to have two sub modes called raw and cooked, where cooked is the old default behaviour and raw can be used to bypass the line-editing support of the native terminal. Using raw mode it is possible to read keystrokes as they occur without the user having to press Enter. Also, the raw mode does not echo the typed characters to stdout.
The shell now prints a help message explaining how to interrupt a running command when stuck executing a command for longer than 5 seconds.
STDLIB
The join(Binaries, Separator) function that joins a list of binaries has been added to the binary module.
By default, sets created by module sets will now be represented as maps.
Module re has been updated to use the newer PCRE2 library instead of the PCRE library.
There is a new zstd module that does Zstandard compression.
I don’t know much about the SBOM generation tooling, but is there a way to make it formatted with line breaks? The advantage of a human readable format such as JSON is that it is supposed to be human readable.
Call me obtuse, I’d quite like be able to browse it on the website without having to download it and run a command on it :).
I’d also expect that the official OTP site will/should be held up as a paragon of best practice, so whatever it does will likely be mimicked by others. Is there any reason not to have it human readable in the repo?
I’m not sure a 3.5 MB json file will be more or less human readable if it is formatted nicely
As the tool we use to generate the sbom generates a formatted json document, I think that we also should do that after we have processed it. What do you think @kiko ?
Sure, we can generate a nicely formatted json. The nicely formatted json is 5.3 MB.
I doubt anyone reads this as a raw text file (187,000+ lines), but we can deliver a formatted json so that our users do not need to run the one liner script.
Hello everyone.

error installing version: failed to run install callback: exit status 1
The build of release 28.0-rc2 with kerl configuration options kco1 is successful (without wx).
Releases 27.3 and 28.0-rc1 were build without setting kerl options (without errors) .
The tooling has not changed.
There is a problem with asdf (this is due to the upgrade to 0.16.0) uninstall is not working #331.
There was the workaround for this: rm -rf .asdf/installs/erlang/<version>
The asdf uninstall erlang <version> command is currently working.
There is this printout in the logs. It means that you cannot use webview which you enable to configure. So you need to check your wx installation to see why webview is not there.
If you build Erlang 28-rc2 directly without asdf and without enabling webview, does it work then?
