# roadmap | ||
|
||
etcd uses GitHub milestones to track all tasks in each major or minor release. The roadmap.md file only records the | ||
most important tasks for each release. The list is based on current maintainers capacity that may shift over time. | ||
Proposed milestones is what we think we can deliver with people we have. If we have more support on the important | ||
stuff, we could pick up more items from backlog. Note that etcd will continue to mainly focus on technical debt over | ||
the next few major or minor releases. | ||
|
||
Each item has an assigned priority: | ||
- P0 - Critical for the current milestone, and blocks the release. | ||
- P1 - Important for the current milestone, and critical for the next milestone. | ||
- P2 - Nice to have, can be always skipped and should not block anything. | ||
|
||
