 ## Release History
 
-### In Development:
-
-**Breaking Changes:**
-
-TBD
+### 0.12.1 (2024-12-18)
 
 **New Features:**
 
-* When auto-flushing is enabled, metrics are now also flushed before the process exits. In previous versions, you needed to do this manually by calling `metrics.flush()` at the every end of your program.
-
-    You will still need to flush manually if you set `flushIntervalSeconds` to `0` or you are quitting your program by calling `process.exit()` [(which interrupts a variety of operations)](https://nodejs.org/docs/latest/api/process.html#processexitcode).

-**Deprecations:**

+* When auto-flushing is enabled, metrics are now also flushed before the process exits. In previous versions, you needed to do this manually by calling `metrics.flush()` at the every end of your program. (#141)
 
-**Maintenance:**
+    You will still need to flush manually if you set `flushIntervalSeconds` to `0` or `stop()` (see below) if you are quitting your program by calling `process.exit()` [(which interrupts a variety of operations)](https://nodejs.org/docs/latest/api/process.html#processexitcode).
 
-TBD
+* A new `stop()` method disables auto-flushing and flushes any currently buffered metrics (you can leave metrics in the buffer instead with the `flush` option: `stop({flush: false})`). (#141)
