+## Update (March 31st, 2025)
+
+To improve inference efficiency and streamline data collation, we’ve decided to drop a small number of exceptionally long samples from the dataset.
+
+We’re using the `meta-llama/Llama-3.2-1B-instruct` tokenizer, and the filtering criteria are as follows:
+- Github_easy: Samples longer than 1024 tokens — 5 out of 582 removed
+- Github_medium: Samples longer than 2048 tokens — 7 out of 593 removed
+- Github_hard: Samples longer than 8192 tokens — 4 out of 372 removed
+- Other subsets are not touched
+
+Since the number of discarded samples is minimal, this change is expected to have at most a 1% impact on results.

 ## ⚠️ Important Update (March 10th, 2025)
 
 We have restructured the dataset to include train/val/test splits. If you downloaded the dataset before this date, you might encounter errors like `KeyError: 'Github_easy'`.
