This time, Cline v3.15 has made so many changes. In the words of the official article: to make Cline better as your "daily driver" and make your experience smoother and more advanced. The following are all the updates of the current version:

Here are some of the main improvements:

1. No more focus stealing!: Optimize the smoothness of user interaction when editing files

It solves the pain point that users cannot perform other operations while editing files in Cline.  The effect is immediate. When editing in Cline, users can view other codes, prepare the next prompt, or update context files, thus speeding up the development cycle.

2. Task Timeline: Enhance task transparency and understanding

Visualize the complex task execution process and convert it into an easy-to-understand "storyboard". It is very similar to the visualization stage display in the CI/CD pipeline, allowing developers to clearly see the status of each step from code submission to deployment and find problems in time. In AI development, a "task" may include multiple steps such as data preprocessing, model calling, and post-processing. It is equally important to visualize it.

3. Gemini Implicit Caching: Significantly reduce the cost of using Gemini 2.5 Pro

The cost of repeated prompts is reduced through automated caching mechanisms, making powerful language models more affordable. It reminds me of the "memoization" technology in programming or various caching strategies in Web development (browser caching, CDN caching, database query caching). The core idea of ​​them is to avoid repeated expensive operations and trade space for time. In LLM applications, API calls are one of the main sources of cost and delay. Intelligent caching can greatly improve user experience and economic benefits.

4. Open-sourcing Cline's Docs: Promoting community collaboration and documentation

Manage the documents as community resources and encourage users to contribute and improve directly. As described by the official website, a large part of this major version update is the opinions and code provided by community users, which is also due to the openness of Cline. This time, the Cline documents are open source, so that the documents can be more accurate, fresher, and contain more of everyone's wisdom and experience. Now users can contribute documents by submitting pull requests, just like contributing code.

These updates from Cline indicate that AI application development is gradually moving from “handmade workshop”-style exploration to a more standardized, efficient, and engineered stage.
