-# Synapse 1.112.0 (2024-07-30)
-
-This security release is to update our locked dependency on Twisted to 24.7.0rc1, which includes a security fix for [CVE-2024-41671 / GHSA-c8m8-j448-xjx7: Disordered HTTP pipeline response in twisted.web, again](https://github.com/twisted/twisted/security/advisories/GHSA-c8m8-j448-xjx7).
-
-Note that this security fix is also available as **Synapse 1.111.1**, which does not include the rest of the changes in Synapse 1.112.0.
-
-This issue means that, if multiple HTTP requests are pipelined in the same TCP connection, Synapse can send responses to the wrong HTTP request.
-If a reverse proxy was configured to use HTTP pipelining, this could result in responses being sent to the wrong user, severely harming confidentiality.
-
-With that said, despite being a high severity issue, **we consider it unlikely that Synapse installations will be affected**.
-The use of HTTP pipelining in this fashion would cause worse performance for clients (request-response latencies would be increased as users' responses would be artificially blocked behind other users' slow requests). Further, Nginx and Haproxy, two common reverse proxies, do not appear to support configuring their upstreams to use HTTP pipelining and thus would not be affected. For both of these reasons, we consider it unlikely that a Synapse deployment would be set up in such a configuration.
-
-Despite that, we cannot rule out that some installations may exist with this unusual setup and so we are releasing this security update today.
-
-**pip users:** Note that by default, upgrading Synapse using pip will not automatically upgrade Twisted. **Please manually install the new version of Twisted** using `pip install Twisted==24.7.0rc1`. Note also that even the `--upgrade-strategy=eager` flag to `pip install -U matrix-synapse` will not upgrade Twisted to a patched version because it is only a release candidate at this time.
-
-### Internal Changes
-
-- Upgrade locked dependency on Twisted to 24.7.0rc1. ([\#17502](https://github.com/element-hq/synapse/issues/17502))
-
-
-# Synapse 1.112.0rc1 (2024-07-23)
-
-Please note that this release candidate does not include the security dependency update
-included in version 1.111.1 as this version was released before 1.111.1.
-The same security fix can be found in the full release of 1.112.0.

-##### Red Hat Enterprise Linux / Rocky Linux
-
-*Note: The term "RHEL" below refers to both Red Hat Enterprise Linux and Rocky Linux. The distributions are 1:1 binary compatible.*
-
-It's recommended to use the latest Python versions. 
-
-RHEL 8 in particular ships with Python 3.6 by default which is EOL and therefore no longer supported by Synapse. RHEL 9 ship with Python 3.9 which is still supported by the Python core team as of this writing. However, newer Python versions provide significant performance improvements and they're available in official distributions' repositories. Therefore it's recommended to use them.
-
-Python 3.11 and 3.12 are available for both RHEL 8 and 9.
-
-These commands should be run as root user.
-
-RHEL 8
-```bash
-# Enable PowerTools repository
-dnf config-manager --set-enabled powertools
-```
-RHEL 9
-```bash
-# Enable CodeReady Linux Builder repository
-crb enable
-```
-
-Install new version of Python. You only need one of these:
-```bash
-# Python 3.11
-dnf install python3.11 python3.11-devel
-```
-```bash
-# Python 3.12
-dnf install python3.12 python3.12-devel
-```
-Finally, install common prerequisites
-```bash
-dnf install libicu libicu-devel libpq5 libpq5-devel lz4 pkgconf 
-dnf group install "Development Tools"
-```
-###### Using venv module instead of virtualenv command
-
-It's recommended to use Python venv module directly rather than the virtualenv command.
-* On RHEL 9, virtualenv is only available on [EPEL](https://docs.fedoraproject.org/en-US/epel/).
-* On RHEL 8, virtualenv is based on Python 3.6. It does not support creating 3.11/3.12 virtual environments.
-
-Here's an example of creating Python 3.12 virtual environment and installing Synapse from PyPI. 
-
-```bash
-mkdir -p ~/synapse
-# To use Python 3.11, simply use the command "python3.11" instead.
-python3.12 -m venv ~/synapse/env
-source ~/synapse/env/bin/activate
