-## Benchmarks
-
-Performance benchmarks are available to measure runtime, memory usage, and CPU performance of search queries.
-
-### Running Benchmarks
-
-```bash
-export SERPAPI_KEY=your_api_key_here
-cargo bench --bench search_query
-```
-
-### Benchmark Results
-
-The benchmark executes the same search query ("coffee" in Austin, TX) 10 times and measures runtime, memory usage, and JSON parsing performance.
-
-#### Search Query Performance
-
-| Metric | Time (mean) | Time (std dev) | Iterations |
-|--------|-------------|----------------|------------|
-| search_with_parsing | 263.01 ms | 5.61 ms | 10 |

-**Latest benchmark results:**
-
-**Runtime Performance:**
-- **Mean time:** 263.01 ms
-- **Standard deviation:** 5.61 ms
-- **95% Confidence interval:** 257.92 ms - 269.14 ms
-- **Samples collected:** 10
-
-**Memory Usage:**
-- **Memory Delta (mean):** 16.98 KB (0.02 MB)
-- **Memory Delta (std dev):** 264.29 KB (0.26 MB)
-- **Peak Memory:** 16.05 MB

-> - Runtime performance of the search API call
-> - Memory usage during search operations
-> - CPU performance of JSON parsing and data access
+### Changes log
+- 1.1.0: Always reuse the same client object instead of creating a new one for each search.
+  - This is a breaking change for the API because the client must be unwrapped in the main function.
+    ```rust
+    # now: 1.1
+    let client = Client::new(default).unwrap();
+    # old: 1.0
+    let client = Client::new(default);
+    ```
+- 1.0.0: Initial release
