Here’s a summary of what this software update contains:

Daedalus 0.11 has a couple of user interface tweaks to improve the user experience, and includes some fixes in preparation for the upcoming release of Daedalus for Linux. Cardano SL 1.3 includes significant improvements to the speed of syncing the blockchain. Tests have shown wallet syncing occurring between 1.5 and 4 times faster, depending on network environment. The network relays can also support more users syncing at once which will reduce congestion at busy times. The release includes improvements to the on-disk storage of the blockchain to use fewer files and use less disk space. The release includes a fix for a problem where a node would sometimes fail to reconnect to the network after an interruption in the internet connection.

For exchanges and other third party integrations, the new wallet V1 API is now available and supported, and the old V0 API is now deprecated. A performance problem for exchanges seeing high disk I/O has been resolved.

Daedalus 0.11 uses significantly less memory, which is a benefit for users with older or less powerful computers, while other tweaks improve the user experience. Improvements to Cardano SL 1.3 mean that network performance will be enhanced. Exchanges will also see better performance.
