Hacktoberfest 2025, a global celebration of open-source collaboration organized by DigitalOcean, is set to begin on October 1, inviting participants to contribute by creating six accepted pull or merge requests to receive a Hacktoberfest t-shirt and have a tree planted in their name. This year, the event features changes in awards and the introduction of the Hackstronaut mascot, with participants earning digital pins as they complete contributions. Major League Hacking (MLH) returns as a sponsor, hosting Global Hack Week: Open Source from October 10 to 16, a virtual festival designed to enhance participants' open-source skills. The event encourages contributions in various forms, including technical coding, non-technical skills, mentoring, and organizing events, while urging participants to share their experiences on social media using the #hacktoberfest hashtag. The initiative underscores the importance of sponsors such as DigitalOcean, MLH, Auth0, and AMD, and emphasizes the community spirit in open-source projects.
