Prometheus 2.14.0 is now out, following on from 2.13.0 with many fixes and improvements.
The big new feature is the new UI based on React, which is still a work in progress and largely looks the same as the existing UI. The existing UI also gained head cardinality statistics and alert filtering by state.
Remote write delays after compaction have been fixed, and resharding is avoided when samples can't be sent. WAL loading at startup has been optimised a bit.
压缩后的远程写延迟已得到修复，当无法发送样本时避免了重新分片。启动时WAL加载已进行了一些优化。
