 Simplicity and small file size! We followed the [docs](https://libvips.github.io/libvips/install.html) for `libvips` install. But because AWS Lambda already has ImageMagick and lots of the needed dependencies, the work was very basic.
 
-We used the `lambci/lambda:build-ruby2.5` Docker image from the [docker-lambda](https://github.com/lambci/docker-lambda) project. From there we only had to install a few more dependencies to get libvips installed. The current version is `v8.7.4` and easy to configure if you need something else.
+We used the `lambci/lambda:build-ruby2.7` Docker image from the [docker-lambda](https://github.com/lambci/docker-lambda) project. From there we only had to install a few more dependencies to get libvips installed. The current version is `v8.9.2` and easy to configure if you need something else.
 
 Lastly, we were happy to find that `glib` and `gobject` were already installed and all that was needed were some simple sym links so FFI could load these libraries.
 
 
 ## Contents
 
-Because of the way we build `libvips` by using existing libraries already installed on AWS Lambda, the resulting layer is very small. Only around `10MB` in total un-compressed size.
+Current size of the layer's un-compressed contents is around `15MB` in size.
