+## Overview
+
+Pactus Blockchain [Version 1.1.5 (Cape Town)](https://github.com/pactus-project/pactus/releases/tag/v1.1.5)
+is now available for download.
+This release includes the following applications:
+
+- [Pactus GUI]({{ site.baseurl }}/user-guides/pactus-gui/):
+  The graphical user interface (GUI) for the Pactus node that is suitable
+  for both beginners and experienced users.
+
+- [Pactus Daemon]({{ site.baseurl }}/user-guides/pactus-daemon/):
+  The command-line interface (CLI) for the Pactus node that is suitable for experienced users.
+
+- [Pactus Shell]({{ site.baseurl }}/user-guides/pactus-shell/):
+  The command-line tool that allows users to interact with a Pactus node.
+
+- [Pactus Wallet]({{ site.baseurl }}/user-guides/pactus-wallet/):
+  The wallet software that allows users to manage their wallet and send transactions
+  without the need to sync the entire blockchain.
+
+## Highlights
+
+### Rate limit
+
+This version applies a rate limit to the messages in the general topics including blocks and transactions.
+This will help nodes to manage the network traffic in times of network congestion or spam attacks.
+
+### Dynamic fee
+
+To prevent attackers from sending spam transactions, a dynamic fee model is introduced in this patch.
+Each node can define a minimum fee that is defaulted to 0.000001 PAC.
+However, if the transaction pool becomes full, the transaction fee can increase up to 1 PAC.
+
+To ensure network stability and security,
+it is recommended that all validators upgrade to this version as soon as they can.
+
