Own Id: OTP-19747 Application(s): erts Related Id(s): PR-10126 - In the documentation for the `compile` module, a section has been added with recommendations for implementors of languages running on the BEAM. Documentation has also been added for the `to_abstr`, `to_exp`, and `from_abstr` options. The documentation for erlc now lists `.abstr` as one of the supported options. When compiling with the `to_abstr` option, the resulting `.abstr` file now retains any `-doc` attributes present in the source code. Own Id: OTP-19784 Application(s): compiler, erts Related Id(s): PR-10230, PR-10234 - Native records as described in EEP-79 has been implemented. A native record is a data structure similar to the traditional tuple-based records, except that is a true data type. Native records are considered experimental in Erlang/OTP 29 and possibly also in Erlang/OTP 30, meaning that their behavior may change, potentially requiring updates to applications that use them. Own Id: OTP-19785 Application(s): compiler, dialyzer, erts, stdlib Related Id(s): PR-10617 - The guard BIF `is_integer/3` has been added. It follows the design of the original EEP-16, only changing the name from `is_between` to `is_integer`. This BIF takes in 3 parameters, `Term`, `LowerBound`, and `UpperBound`. It returns `true` if `Term`, `LowerBound`, and `UpperBound` are all integers, and `LowerBound =< Term =< UpperBound`; otherwise, it returns false. Example: 1> I = 42. 2> is_integer(I, 0, 100). true Own Id: OTP-19809 Application(s): compiler, dialyzer, erts Related Id(s): PR-10276 - There are new functions for random permutation of a list: rand:shuffle/1 and rand:shuffle_s/2.

Own Id: OTP-19842 Application(s): erts, kernel *** POTENTIAL INCOMPATIBILITY *** - Function application is now left associative. That means one can now write: f(X)(Y) instead of: (f(X))(Y) Own Id: OTP-19866 Application(s): compiler Related Id(s): PR-9223 - There will now be a warning when exporting variables out of a subexpression. For example: case file:open(File, AllOpts = [write,{encoding,utf8}]) of {ok,Fd} -> {Fd,AllOpts} end To avoid the warning, this can be rewritten to: AllOpts = [write,{encoding,utf8}], case file:open(File, AllOpts) of {ok,Fd} -> {Fd,AllOpts} end The warning can be suppressed by giving option `nowarn_export_var_subexpr` to the compiler. Own Id: OTP-19898 Application(s): compiler, stdlib Related Id(s): PR-9134 - By default, the compiler will now warn for uses of the `and` and `or` operators. This warning can be suppressed using the `nowarn_obsolete_bool_op` compiler option. Own Id: OTP-19918 Application(s): compiler Related Id(s): PR-9115 - Before Erlang/OTP 29, attempting to bind variables in a comprehension would compile successfully but fail at runtime.

Own Id: OTP-19927 Application(s): compiler, stdlib Related Id(s): PR-9153 *** POTENTIAL INCOMPATIBILITY *** - There will now be a warning when using the `catch` operator, which has been deprecated for a long time.

Own Id: OTP-19968 Application(s): compiler Related Id(s): PR-10646 # POTENTIAL INCOMPATIBILITIES - Fixed (`inet`) module selection when calling (`gen_tcp`) listen and connect and (`gen_udp`) open. Depending on the order of the options, the module option (`tcp_module` or `udp_module`) was sometimes ignored. Own Id: OTP-19695 Application(s): kernel Related Id(s): GH-9822, PR-10013 - `ssh:stop_deamon` now uses `supervisor:stop` for shutting down daemons. With this change, the scenario when `ssh:stop_daemon` is called for a non-existing process results in calling process exiting. Previously an error tuple was returned (which was not documented).

Own Id: OTP-19652 Related Id(s): PR-9790 - Automated vendor vulnerability handling has been added. 1. Verifies that OTP reported Github Securities exists in the published OpenVEX statements. 2.

This issue only happened for pull requests that modified vendor files. Scheduled vendor vulnerability scans were correct. The behavior has not been corrected and pull requests on `maint` and `maint-`XX will work as expected, analyzing their vendor dependencies. To create issues when vendor vulnerabilities are detected, use permissions from the Erlang Vendor Scanner Bot. Own Id: OTP-19775 Related Id(s): PR-10206, PR-10213, PR-10218, PR-10220, PR-10223 - Create OpenVEX statement in Erlang/OTP to state that the wxWindows vendor vulnerability CVE-2024-58249 does not affect OTP-28. Own Id: OTP-19778 Related Id(s): PR-10209 - `.github/scripts/otp-compliance.es vex run` was ignoring certain OpenVEX statements if the CVE name existed. That meant an OpenVEX statement could say "under_investigation" and the CVE reported a vulnerability, and simply based on the CVE Id, the script would ignore it as the CVE Id exists in OpenVEX. The script has been updated to filter CVE results that already exist in OpenVEX statements. Own Id: OTP-19779 Related Id(s): PR-10209 - The old-style type tests in guards (`integer`, `atom` and so on) have been scheduled for removal in Erlang/OTP 30.

This has been corrected so that the compiler will never emit code that uses the `set_tuple_element` instruction. In a future release, support for the `set_tuple_element` will be removed from the runtime system. Own Id: OTP-19751 Related Id(s): GH-10125, PR-10144 ## Improvements and New Features - In comprehensions, a generator that builds a list with a single element will now be optimized to avoid building and matching the list.
