+
+In v5.0.1, minor bug and security related issue was fixed.
+
+* deb: cleanup /var/run correctly when removing `fluent-package`.
+* Update bundled protocol-http1 to 0.15.1 to reduce attack vector (HTTP
+  Request/Response smuggling vulnerability). See [CVE-2023-38697](https://nvd.nist.gov/vuln/detail/CVE-2023-38697).
+  GitHub advisory was also published as [GHSA-6jwc-qr2q-7xwj](https://github.com/advisories/GHSA-6jwc-qr2q-7xwj).
+
+## Release v5.0.0 - 2023/07/28
+
+### News
+
+**fluent-package v5.0.0 is a RC (Release Candidate) version of fluent-package v5 series. We are planning to publish GA (General Availability) version of v5 series at the end of Aug 2023.**
+
+* `td-agent` is renamed to `fluent-package`. (#448,#449,#463,#518)
+  * This represents current community-oriented development styles well.
+* Debian 12 (bookworm) has been supported. (#462,#509)
+* Removed Ubuntu 16.04 (xenial), Ubuntu 18.04 (bionic) support. (#457,#509)
+* Amazon Linux 2023 has been supported. (#459)
+* Introduced new package signing key. The new key will be used in the future
+  release. we still use using old signing key for a while. (#507)
+
+Not only changing package name, but also there are some notable changes.
+Basically, for `td-agent` v4 users, it aims to keep compatibility as far as possible
+by executing the migration process with copying old files or providing
+symbolic links for it.
+
+If you created custom service units, you must manually modify the old file to the new path.
+For example, you must update such as: `D_PRELOAD`, `GEM_HOME`, `GEM_PATH`, path of `fluentd` and so on.
+
+#### For all platform:
+
+* The content of `fluent-package` changed to install under `/opt/fluent`. (e.g. `c:/opt/fluent` for windows) (#464)
+* During upgrade install process from v4, it respects the old content
+  and path of log files as far as possible. (#489,#500,#505)
+* `/usr/sbin/td-agent` and `/usr/sbin/td-agent-gem` was changed to
+  `/usr/sbin/fluentd` and `/usr/sbin/fluent-gem`. For backward
+  compatibility, the symbolic link is provided for upgrade users. (#531)
+* Changed the path of example default configuration file to `/opt/fluent/share/fluentd.conf`. (#525,#528)
+
+#### For Debian/Ubuntu user:
+
+* Debian 12 (bookworm) has been supported. (#462,#509)
+* Removed Ubuntu 16.04 (xenial), Ubuntu 18.04 (bionic) support. (#457,#509)
+* deb: the service file is changed to `fluentd.service`.
+  It provides `td-agent` as an alias. Note that if you
+  want to keep using `td-agent` as a service name, you must
+  explicitly execute the following commands: (#461,#516)
+  
+  ```
+  $ sudo systemctl stop td-agent
+  $ (upgrade to fluent-package...)
+  $ sudo systemctl unmask td-agent
+  $ sudo systemctl enable --now fluentd
+  ```
+  
+* deb: user/group name was changed to `_fluentd`. This change is
+  introduced to follow Debian policy. For backward compatibility, if 
+  you upgraded from v4, `td-agent` user/group remains as same
+  `UID`/`GID` of `_fluentd`. This change makes easy to
+  keep using `/etc/logrotate.d/td-agent` as is.  (#475,#519)
+  * Note that process or file owner of `fluent-package` is displayed
+    as `td-agent` instead of `fluentd`.
+* deb: the path of service configuration file is changed to
+  `/etc/default/fluentd`. (#461)
+* deb: `fluentd-apt-source` was renamed to `fluent-apt-source`.
+  * You can remove transitional `fluentd-apt-source` after upgrading
+    to `fluent-apt-source`. (#507,#514,#515)
+* deb: for LTS users, added `fluent-lts-apt-source` package (#541)
+
+#### For RHEL user:
+
+* rpm: the service file is changed to `fluentd.service`.
+  It provides `td-agent` as an alias. Note that if you
+  want to keep using `td-agent` as a service name, you must
+  explicitly execute the following commands: (#461,#516)
+  
+  ```
+  $ sudo systemctl enable fluentd
+  ```
+
+* rpm: user/group name was changed to fluentd. For backward
+  compatibility, if you upgraded from v4, `td-agent` user/group
+  remains as same `UID`/`GID` of `fluentd`. This change makes easy to
+  keep using `/etc/logrotate.d/td-agent` as is. (#475,#519)
+  * Note that process or file owner of `fluent-package` is displayed
+    as `td-agent` instead of `fluentd`.
+* rpm: the path of service configuration file is changed to
+  `/etc/sysconfig/fluentd`. (#461)
+* rpm: prelink configuration was removed. (#472,#529)
+  * In recent days, it is common to disable prelink configuration. If
+  you upgrade from v4, that configuration file
+  (`/etc/sysconfig/prelink.conf.d/td-agent-ruby.conf`) itself will be
+  removed or the entry about `td-agent` will be removed from
+  `/etc/sysconfig/prelink.conf`.
+* rpm: added support for Amazon Linux 2023. (#459)
+* rpm: fixed build failure on CentOS 7 aarch64 (#545)
+
+#### For Windows user:
+
+* msi: renamed to "Fluent Package" (#463,#466,#471)
+* msi: the default install path of `fluent-package` was changed to `c:/opt/fluent`.
+  Note that old log files are kept as is. The following files are migrated to the
+  new path: (#466,#469,#487)
+  
+  * `c:/opt/td-agent/etc/td-agent/td-agent.conf`
+  * `c:/opt/td-agent/etc/plugins/*`
+* msi: the prefix of batch files were renamed to `fluent*`.
+  Thus `td-agent-prompt.bat` was renamed to `fluent-package-prompt.bat`. (#484)
+* msi: disable auto starting service after install. (#521)
+
+  * If you want to start `fluentd` as a service, execute the following command with administrator privileges.
+  
+  ```
+  > net start fluentdwinsvc
+  ```
+
+* msi: stop customizing icons for file browser (#469)
+* msi: update resources for `fluent-package` (#470)
+* msi: changed the default path of buffer/failed_records (#527)
+
+#### For macOS user:
+
+WARNING: Currently we have no plan to release dmg version of `fluent-package` yet.
+It is just modified to be a minimally buildable state, it is for testing purpose only.
+
+* dmg: renamed to `fluent-package` (#474,#478,#479,#480,#481,#482,#483)
+  * Note that the .dmg package support will be dropped in the future
+  release. We plans to migrate for `homebrew` ecosystem.
+* dms: update resources for `fluent-package` (#473)

-  GitHub advisory was also published as [GHSA-6jwc-qr2q-7xwj](https://github.com/advisories/GHSA-6jwc-qr2q-7xwj).
-
-## Release v5.0.0 - 2023/07/28
-
-### News
-
-**fluent-package v5.0.0 is a RC (Release Candidate) version of fluent-package v5 series. We are planning to publish GA (General Availability) version of v5 series at the end of Aug 2023.**
-
-* `td-agent` is renamed to `fluent-package`. (#448,#449,#463,#518)
-  * This represents current community-oriented development styles well.
-* Debian 12 (bookworm) has been supported. (#462,#509)
-* Removed Ubuntu 16.04 (xenial), Ubuntu 18.04 (bionic) support. (#457,#509)
-* Amazon Linux 2023 has been supported. (#459)
-* Introduced new package signing key. The new key will be used in the future
-  release. we still use using old signing key for a while. (#507)
-
-Not only changing package name, but also there are some notable changes.
-Basically, for `td-agent` v4 users, it aims to keep compatibility as far as possible
-by executing the migration process with copying old files or providing
-symbolic links for it.
-
-If you created custom service units, you must manually modify the old file to the new path.
-For example, you must update such as: `D_PRELOAD`, `GEM_HOME`, `GEM_PATH`, path of `fluentd` and so on.
-
-#### For all platform:
-
-* The content of `fluent-package` changed to install under `/opt/fluent`. (e.g. `c:/opt/fluent` for windows) (#464)
-* During upgrade install process from v4, it respects the old content
-  and path of log files as far as possible. (#489,#500,#505)
-* `/usr/sbin/td-agent` and `/usr/sbin/td-agent-gem` was changed to
-  `/usr/sbin/fluentd` and `/usr/sbin/fluent-gem`. For backward
-  compatibility, the symbolic link is provided for upgrade users. (#531)
-* Changed the path of example default configuration file to `/opt/fluent/share/fluentd.conf`. (#525,#528)
-
-#### For Debian/Ubuntu user:
-
-* Debian 12 (bookworm) has been supported. (#462,#509)
-* Removed Ubuntu 16.04 (xenial), Ubuntu 18.04 (bionic) support. (#457,#509)
-* deb: the service file is changed to `fluentd.service`.
-  It provides `td-agent` as an alias. Note that if you
-  want to keep using `td-agent` as a service name, you must
-  explicitly execute the following commands: (#461,#516)
-  
-  ```
-  $ sudo systemctl stop td-agent
-  $ (upgrade to fluent-package...)
-  $ sudo systemctl unmask td-agent
-  $ sudo systemctl enable --now fluentd
-  ```
-  
-* deb: user/group name was changed to `_fluentd`. This change is
-  introduced to follow Debian policy. For backward compatibility, if 
-  you upgraded from v4, `td-agent` user/group remains as same
-  `UID`/`GID` of `_fluentd`. This change makes easy to
-  keep using `/etc/logrotate.d/td-agent` as is.  (#475,#519)
-  * Note that process or file owner of `fluent-package` is displayed
-    as `td-agent` instead of `fluentd`.
-* deb: the path of service configuration file is changed to
-  `/etc/default/fluentd`. (#461)
-* deb: `fluentd-apt-source` was renamed to `fluent-apt-source`.
-  * You can remove transitional `fluentd-apt-source` after upgrading
-    to `fluent-apt-source`. (#507,#514,#515)
-* deb: for LTS users, added `fluent-lts-apt-source` package (#541)
-
-#### For RHEL user:
-
-* rpm: the service file is changed to `fluentd.service`.
-  It provides `td-agent` as an alias. Note that if you
-  want to keep using `td-agent` as a service name, you must
-  explicitly execute the following commands: (#461,#516)
-  
-  ```
-  $ sudo systemctl enable fluentd
-  ```
-
-* rpm: user/group name was changed to fluentd. For backward
-  compatibility, if you upgraded from v4, `td-agent` user/group
-  remains as same `UID`/`GID` of `fluentd`. This change makes easy to
-  keep using `/etc/logrotate.d/td-agent` as is. (#475,#519)
-  * Note that process or file owner of `fluent-package` is displayed
-    as `td-agent` instead of `fluentd`.
-* rpm: the path of service configuration file is changed to
-  `/etc/sysconfig/fluentd`. (#461)
-* rpm: prelink configuration was removed. (#472,#529)
-  * In recent days, it is common to disable prelink configuration. If
-  you upgrade from v4, that configuration file
-  (`/etc/sysconfig/prelink.conf.d/td-agent-ruby.conf`) itself will be
-  removed or the entry about `td-agent` will be removed from
-  `/etc/sysconfig/prelink.conf`.
-* rpm: added support for Amazon Linux 2023. (#459)
-* rpm: fixed build failure on CentOS 7 aarch64 (#545)
-
-#### For Windows user:
-
-* msi: renamed to "Fluent Package" (#463,#466,#471)
-* msi: the default install path of `fluent-package` was changed to `c:/opt/fluent`.
-  Note that old log files are kept as is. The following files are migrated to the
-  new path: (#466,#469,#487)
-  
-  * `c:/opt/td-agent/etc/td-agent/td-agent.conf`
-  * `c:/opt/td-agent/etc/plugins/*`
-* msi: the prefix of batch files were renamed to `fluent*`.
-  Thus `td-agent-prompt.bat` was renamed to `fluent-package-prompt.bat`. (#484)
-* msi: disable auto starting service after install. (#521)
-
-  * If you want to start `fluentd` as a service, execute the following command with administrator privileges.
-  
-  ```
-  > net start fluentdwinsvc
-  ```
-
-* msi: stop customizing icons for file browser (#469)
-* msi: update resources for `fluent-package` (#470)
-* msi: changed the default path of buffer/failed_records (#527)
-
-#### For macOS user:
-
-WARNING: Currently we have no plan to release dmg version of `fluent-package` yet.
-It is just modified to be a minimally buildable state, it is for testing purpose only.
-
-* dmg: renamed to `fluent-package` (#474,#478,#479,#480,#481,#482,#483)
-  * Note that the .dmg package support will be dropped in the future
-  release. We plans to migrate for `homebrew` ecosystem.
-* dms: update resources for `fluent-package` (#473)
