It is the largest tree frog in Taiwan; females can reach 7 cm (2.8 in) in snout-vent length. It is known from Taipei, Yilan, and Taoyuan. > \- Wikipedia [Zhangixalus prasinatus](https://en.wikipedia.org/wiki/Zhangixalus_prasinatus) During this hard time of COVID-19, it's a pleasure to help people collaborate better with CodiMD. We hope the world will recover from this situation soon. :sunrise: Good news, we have some goodies for CodiMD including: - [Support Prometheus metrics](https://hackmd.io/@codimd/v2_1_0#Support-Prometheus-metrics) - [Cut docker image size by 57%](https://hackmd.io/@codimd/v2_1_0#Cut-docker-image-size-by-57) - [Drop Node 8 Support](https://hackmd.io/@codimd/v2_1_0#Drop-Node-8-Support) ## Highlights ### Support Prometheus metrics CodiMD supports Prometheus metrics from this release. You can even display server metrics and realtime statistics on [Grafana Dashboard](https://grafana.com/grafana/dashboards/12214). See [PR #1507](https://github.com/hackmdio/codimd/pull/1507) for the implementation. Big thanks to [@tarlety](https://github.com/tarlety)!

Some of the improvements are: - [Module size optimization #1484](https://github.com/hackmdio/codimd/pull/1484): All frontend dependencies are moved to `devDependencies` section in package.json, which will be removed during `npm prune` phase. Some dependencies like `aws-sdk` are also replaced with a more specific package `@aws-sdk/client-s3-node`, because we only use s3 for image uploading by far. - [New docker buildpack #1518](https://github.com/hackmdio/codimd/pull/1518): CJK fonts are now optional. ### Drop Node 8 Support Node.JS version 8 has reached its end of life starting from 2020. We now upgraded CodiMD's minimum Node.JS version to 10. The main blocker of this upgrade is the package [`scrypt`](https://www.npmjs.com/package/scrypt) we used for hashing the password. Now it's been replaced with the new package [`scrypt-kdf`](https://www.npmjs.com/package/scrypt-kdf).
