Cursor has officially released version 0.46 on its official website. It has many features. Today, let’s talk about some of the issues that everyone is most concerned about.
1. Do you want to update to version 0.46?
On demand, according to the official forum posts, the Windows version still has some minor issues, so if there is no strong demand, it is not recommended to update. For example, version 0.45 can also use the Claude 3.7 model normally, so there is no need to upgrade to a new version just for this function.
2. Can I use Claude 3.7?
Cursor Pro users can use version 3.7, including the basic 3.7-sonnet and 3.7-sonnet-thinking with reasoning function. Free users can no longer use version 3.7. The official reason given is that too many people are using it.
You can try Windsurf or Trae, but as of now, using Claude 3.7 in Trae requires waiting in line, and it takes a long time to get in line. The official explanation is that there are too many users, so wait for the follow-up.
4. How does Claude 3.7 perform in practice?
The actual test shows that the programming ability is very strong. Basically, the functions that used to require multiple communications to implement using 3.5 can now be completed in one or two times. Of course, in the actual test, it was found that Sonnet-thinking in 3.7 would complicate simple problems and may require you to modify a lot of content. If a similar situation occurs, you can use the 3.5 version or the model without thinking.
5. Why does MCP installation fail?
The reason is simple. The nv and npx methods in Windows cannot find the command. You can refer to my tutorial to operate it. Cursor Master Advanced | Cline and MCP Integration Guide to Make Your AI More Powerful
For more information about MCP, see the Cursor and Claude MCP Learning Guide.
6. Why is the 0.46 version of Composer gone?
This is caused by the new version of UI, Chat and Composer are combined into one. In simple terms, Agent mode corresponds to the agent mode of the original version of Composer; Ask mode corresponds to the original Chat function; Edit mode corresponds to the normal mode of this Composer.
If you are not used to this UI, the official also provides versions before 0.45 for download.
