Red bars overlap a burst. ### Bursts - **Jun 1, 2021 to Jun 1, 2021**: about 12 more stars than usual, peak 12 in one day, a spike that tapers off. Outside explanation: a jump in issues and pull requests. - **Jun 25, 2021 to Jun 30, 2021**: about 45 more stars than usual, peak 12 in one day, a shape we can't classify. Outside explanation: a jump in forks. - **Mar 8, 2022 to Mar 8, 2022**: about 19 more stars than usual, peak 19 in one day, a spike that tapers off. Outside explanation: a jump in forks. - **Apr 12, 2024 to Apr 17, 2024**: about 65 more stars than usual, peak 18 in one day, a spike that tapers off. Outside explanation: a jump in forks. - **Sep 11, 2024 to Sep 13, 2024**: about 61 more stars than usual, peak 31 in one day, a spike that tapers off. No outside explanation found, so this burst is unexplained. - **Oct 17, 2026 to Oct 24, 2026**: about 344 more stars than usual, peak 89 in one day, a shape we can't classify. Outside explanation: a Hacker News post, a jump in forks.
