 ### Features:
 - Create Layer 2 (CDP/LLDP) topology data 
-- Create Layer 3 (IPv4) topology data -> CMK2.3.0 only
+- Create Layer 3 (IPv4) topology data
 - Highlight conetion issues (Speed, Duplex/Half duplex, Native VLAN)
 - Read connection data from the checkmk HW/SW inventory.
 - Works in standalone and distributed monitoring environments
 - Add custom connections (STATIC) for connections that are not in the inventory
 - Optimized for my [CDP](https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/inventory/inv_cdp_cache/), [LLDP](https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/inventory/inv_lldp_cache/) and [IPv4](https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/inventory/inv_ipv4_addresses) inventory plugins
-- Merge CDP, LLDP, STATIC topologies (CMK 2.2.0 only)
-- Can also be used with custom inventory plugins
+- Can also be used with custom inventory plugins (deprecated)
 
 The necessary HW/SW inventory data can be created with my CDP/LLDP/IPv4 inventory plugins.

 ### Requirements
 
 To use this tool:
-- your Checkmk Site must be running at least CMK version 2.2.0p1
+- your Checkmk Site must be running at least CMK version 2.3.0p1
 - the HW/SW inventory must be enabled
 - you need to install/enable an inventory plugin to collect the connection data I.e. my [CDP cache](https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/inventory/inv_cdp_cache/) or [LLDP cache](https://thl-cmk.hopto.org/gitlab/checkmk/vendor-independent/inventory/inv_lldp_cache/) plugins
 - check if the Checkmk HW/SW inventory finds the required data (CDP/LLDP neighbors)
-- the [Network visualization plugin](https://exchange.checkmk.com/p/network-visualization) must be installed (CMK 2.2.0 only, for CMK2.3.0 this is bildin)
 
 **Note**: if you are using my CDP/LLDP/IPv4 plugins update at least to version
