 #### Manager/Pool-related
 
-- Added `INTEGRESQL_TEST_MAX_POOL_SIZE`:
+- Changed `INTEGRESQL_TEST_MAX_POOL_SIZE`:
   - Maximal pool size that won't be exceeded
   - Defaults to "your number of CPU cores 4 times" [`runtime.NumCPU()*4`](https://pkg.go.dev/runtime#NumCPU)
   - Previous default was `500` (hardcoded)
   - This might be a **significant change** for some usecases, please adjust accordingly. The pooling recreation logic is now much faster, there is typically no need to have such a high limit of test-databases **per pool**!
-- Added `INTEGRESQL_TEST_INITIAL_POOL_SIZE`:
+- Changed `INTEGRESQL_TEST_INITIAL_POOL_SIZE`:
   - Initial number of ready DBs prepared in background. The pool is configured to always try to have this number of ready DBs available (it actively tries to recreate databases within the pool in a FIFO manner).
   - Defaults to [`runtime.NumCPU()`](https://pkg.go.dev/runtime#NumCPU)
   - Previous default was `10` (hardcoded)
