+  ## Changes Since Last Alpha Release
+
+  ### `Stdlib` Changes
+
+  + [#11309](https://github.com/ocaml/ocaml/issues/11309), [#11424](https://github.com/ocaml/ocaml/issues/11424), [#11427](https://github.com/ocaml/ocaml/issues/11427), +[#11545](https://github.com/ocaml/ocaml/issues/11545): Add Domain.recommended_domain_count.
+    (Christiano Haesbaert, Konstantin Belousov, review by David Allsopp,
+    KC Sivaramakrishnan, Gabriel Scherer, Nicolas Ojeda Bar)
+
+  - [#11423](https://github.com/ocaml/ocaml/issues/11423): Move the effect exceptions to the Effect module
+    (KC Sivaramakrishnan, Xavier Leroy, Florian Angeletti, review by
+    Florian Angeletti, Xavier Leroy, and KC Sivaramakrishnan)
+
+  - [#11593](https://github.com/ocaml/ocaml/issues/11593): Remove Domain.at_each_spawn
+    (Florian Angeletti, review by Guillaume Munch-Maccagnoni
+    and KC Sivaramakrishnan)
+
+  ### Bug Fixes
+
+  - [#11303](https://github.com/ocaml/ocaml/issues/11303): Ensure that GC is not invoked from bounds check failures
+    (Stephen Dolan, review by Sadiq Jaffer and Xavier Leroy)
+
+  - [#5299](https://github.com/ocaml/ocaml/issues/5299), [#4787](https://github.com/ocaml/ocaml/issues/4787), [#11138](https://github.com/ocaml/ocaml/issues/11138), [#11272](https://github.com/ocaml/ocaml/issues/11272), [#11506](https://github.com/ocaml/ocaml/issues/11506): To help debugging, `Caml_state`
+    now dynamically checks that the domain lock is held and fails
+    otherwise (with a fatal error at most entry points of the C API, or
+    systematically in debug mode). A new variable `Caml_state_opt` is
+    introduced and is `NULL` when the domain lock is not held. This
+    allows to test from C code if the current thread holds its domain lock.
+    (Guillaume Munch-Maccagnoni, review by Florian Angeletti, Damien
+    Doligez, Sadiq Jaffer, Xavier Leroy, and Gabriel Scherer)
+
+  - [#11223](https://github.com/ocaml/ocaml/issues/11223): The serialisation format of custom blocks changed in 4.08,
+    but the deserialiser would still support the pre-4.08 format.  OCaml
+    5.x removed support for this old format and provided a clear error message
+    in this case.
+    (Hugo Heuzard, review by Gabriel Scherer)
+
+  - [#11504](https://github.com/ocaml/ocaml/issues/11504), [#11522](https://github.com/ocaml/ocaml/issues/11522): Use static allocation for `caml_make_float_vect` in
+    no-flat-float-array mode, it's more efficient and avoids a race condition
+    (Xavier Leroy, report by Guillaume Munch-Maccagnoni, review by David Allsopp)
+
+  - [#11461](https://github.com/ocaml/ocaml/issues/11461), [#11466](https://github.com/ocaml/ocaml/issues/11466): Fix `gethostbyaddr` for IPv6 arguments and make it domain-safe
+    (Olivier Nicole, Nicolás Ojeda Bär, David Allsopp and Xavier Leroy,
+    review by the same)
+
+  - [#11479](https://github.com/ocaml/ocaml/issues/11479): Make Unix.symlink domain-safe on Windows

+---
+
+The release of OCaml 5.0.0 is drawing near.
+The standard library has been stabilized and many opam packages already
+work with this release.
+After two alpha releases,  we have released the first beta version to help you update your software and libraries ahead of the release (see below for the installation instructions).
+
+If you find any bugs, please report them [on GitHub issues](https://github.com/ocaml/ocaml/issues).
+
+Compared to the last alpha release, this beta contains many small, internal
+runtime fixes (in particular in the `systhreads` library).
+
+At the user level, the interface of the Domain and Effect module has been tweaked to be (hopefully) more forward-compatible:
+
+- Exceptions related to effects are now defined in the Effecŧ module.
+- The value `Domain.recommended_domain_count` is no longer a constant and the function `Domain.at_each_spawn` has been removed.
+
+With those changes, the standard library should be stable now.
+
+If you are interested in the ongoing list of bug fixes, the
+updated change log for OCaml 5.0.0 is available [on GitHub](https://github.com/ocaml/ocaml/blob/5.0/Changes).
+
+You can also follow the state of the opam ecosystem on [this `opam-repository` issues](https://github.com/ocaml/opam-repository/issues/21526), and at [check.ocamllabs.io](http://check.ocamllabs.io/)
+
+A short summary of the changes since the last alpha release is also available
+below.
+
+
+Installation Instructions
+-------------------------
+
+The base compiler can be installed as an opam switch with the following commands
+on opam 2.1:
+```bash
+opam update
+opam switch create 5.0.0~beta1
+```
+
+For previous versions of opam, the switch creation command line is slightly more verbose:
+```bash
+opam update
+opam switch create 5.0.0~beta1 --repositories=default,beta=git+https://github.com/ocaml/ocaml-beta-repository.git
+```
+
+It might also be interesting to check the new support for parallelism by installing
+the `domainslib` library with
+
+```bash
+opam install domainslib
+```
+
+The source code for the beta release is also available at these addresses:
+
+* [https://github.com/ocaml/ocaml/archive/5.0.0-beta1.tar.gz](https://github.com/ocaml/ocaml/archive/5.0.0-beta1.tar.gz)
+* [https://caml.inria.fr/pub/distrib/ocaml-5.0/ocaml-5.0.0~beta1.tar.gz](https://caml.inria.fr/pub/distrib/ocaml-5.0/ocaml-5.0.0~beta1.tar.gz)
+
+## Fine-Tuned Compiler Configuration
+
+If you want to tweak the configuration of the compiler, you can switch to the option variant with:
+```bash
+opam update
+opam switch create <switch_name> ocaml-variants.5.0.0~beta1+options <option_list>
+```
+where `option_list` is a comma-separated list of `ocaml-option-*` packages. For instance, for a `flambda` and `no-flat-float-array` switch:
+```bash
+opam switch create 5.0.0~beta1+flambda+nffa ocaml-variants.5.0.0~beta1+options ocaml-option-flambda ocaml-option-no-flat-float-array
+```
+The command line above is slightly more complicated for opam versions before 2.1:
+```bash
+opam update
+opam switch create <switch_name> --packages=ocaml-variants.5.0.0~beta1+options,<option_list> --repositories=default,beta=git+https://github.com/ocaml/ocaml-beta-repository.git
+```
+
+In both cases, all available options can be listed with `opam search ocaml-option`.
+
+## Optional opam Alpha Repository
+
+During the beta release, if your dependencies are not yet compatible with OCaml 5.0.0, 
+you might want to check the alpha opam repository: [https://github.com/kit-ty-kate/opam-alpha-repository](https://github.com/kit-ty-kate/opam-alpha-repository).
+
+Which can be installed with
+```bash
+opam repo add alpha git+https://github.com/kit-ty-kate/opam-alpha-repository.git
+```
+You can check that the alpha repository has been correctly installed with
+```bash
+$ opam repo
+<><> Repository configuration for switch 5.0.0~beta1 <><><><><><><><><><><><><>
+ 1 alpha   git+https://github.com/kit-ty-kate/opam-alpha-repository.git
+ 2 default https://opam.ocaml.org
+```
+This alpha repository contains various fixes that are in the process of being upstreamed,
+but it should be less and less required with the progress of the beta release.

+
+The release of OCaml 5.0.0 is drawing close.
+
+In order to test the most recent bug fixes and to help you update your software
+and libraries ahead of the release, we have released a second beta version of
+OCaml 5.0.0, (see below for the installation instructions).
+
+If you find any bugs, please report them on [OCaml's issue tracker](https://github.com/ocaml/ocaml/issues).
+
+Compared to the first beta release, this second beta contains many small
+internal standard library fixes, one configuration fix and many small bug fixes.
+
+We also have few updates of the documentation, which introduce two new alerts:
+one for the unstable modules Domain and Effect, and another for functions doing
+unsynchronized_access to mutable state in the standard library. Those two alerts
+are disabled by default, but are available for interested users.
+
+The first release candidate for OCaml 5.0.0 is expected to follow closely this
+second beta release.
+
+If you are interested in the ongoing list of bug fixes, the updated change log
+for OCaml 5.0.0 is available [on GitHub](https://github.com/ocaml/ocaml/blob/5.0/Changes).

+
+For previous versions of opam, the switch creation command line is slightly more verbose:
+```bash
