Why these Tags: an agent read the README and quoted it
- Logging library from the description:
Apache Log4j is a versatile, feature-rich, efficient logging API and backend for Java.
An agent gave these Tags from the fixed Tag list in the AwesomeRepos source code. A code check kept each Tag only when its quote is in the text. A wrong Tag? Report an error with the form at the end of this page.
Admitted to the Repository Index on Nov 10, 2026: 3,644 stars on 2026-11-10.

The timeline comes from the creation date and the releases on the Repository Host, the Admission, the Star History, and the Observations. Star milestones show only when the Star History records the day. The list shows up to 5 stable releases from the latest 10 releases recorded. When none of them is stable, one item counts the pre-releases. On the chart of net stars each day, a solid line marks each recorded release.

Health facts
Measured facts in four separate dimensions, each with a date and a source. AwesomeRepos does not add them into one score. AwesomeRepos reads the weekly commits, the changelog, and the community files each week for the 5,000 visible repositories with the most stars and for each rising repository. How AwesomeRepos defines each check
Copies a prompt for a coding agent. It has 1 task for the maintainers of apache/logging-log4j2.
Improve the Health Facts of the GitHub repository apache/logging-log4j2. AwesomeRepos measures facts about how a repository is maintained, released, secured, and documented. Its page for this repository is https://awesomerepos.com/apache/logging-log4j2. A change to the repository can improve each of the item below. Each item gives the measured fact or score, and a task. 1. The newest release tag is a semantic version Fact: The newest release tag is rel/2.25.5. Rule: The tag of the newest release has the form 1.2.3 or v1.2.3, with an optional pre-release or build part. There is no data when the repository has no release. Task: Make the next release tag a semantic version (1.2.3 or v1.2.3). Do not change or delete a published tag. If a release tool makes the tags, configure it for semantic versions, and write the version scheme in the contributing guide. Rules for this work: - Each file must be true for this project. Do not copy text that does not apply to it. - Do not choose a licence, a contact, or a release version for me. Ask me. - Do not publish a release, change a repository setting, or push to the default branch. Make the changes on a new branch. - Keep each change small, and run the checks of this repository before you finish. - At the end, list each item as DONE, SKIPPED (with the reason), or NEEDS A DECISION (with the question). AwesomeRepos reads these facts again in its next scan. The definitions of the checks: https://awesomerepos.com/health-facts
