v4.45.2 v5.0.7 is released. (Security Release)
This release includes security enhancement for all users.

## !!! Important SECURITY enhancement !!!
* Fix DoS attack vulnerability in VMess Option Processing. (Thanks @nekohasekai )

## Security Advisory
This update fixes a DoS vulnerability in V2Ray. This vulnerability allows a VMess Client with authentication information controlled by an attacker to crash a VMess Server by sending a specially crafted VMess handshake message with an invalid option or encryption type. This vulnerability does NOT allow the attacker to retrieve any information(other than it used an unpatched version of the software) and does NOT allow an attacker to control the unpatched software or system. It is strongly recommended for all users to apply this security update at the earliest possible opportunity. We would like to thank @nekohasekai for the discovery of this vulnerability.

此更新修复了在 V2Ray 中的一个拒绝服务攻击漏洞。这个漏洞允许攻击者控制的拥有认证信息的 VMess 客户端迫使 VMess 服务器端崩溃。这个漏洞可以通过在 VMess 握手阶段由客户端发送一个恶意的数据包被触发,触发漏洞数据包拥有无效的选项或加密方式。 攻击者 无法 通过这个漏洞获取任何信息(除客户端尚未应用此安全更新以外),也 不会 允许攻击者控制客户端软件或系统。强烈推荐所有用户在第一时间应用本安全更新。我们在此感谢 @nekohasekai 发现此漏洞。

Edit: Fixed a typo. Last version of this document withdrawn.

Telegram Auto-Delete Messages in Any Chat

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
