Inc snapcraft version

The program generates a path for every leaf node in the
file-to-be-merged. It does not escape them if they contain a dot, as
the path-expressions document mentions is necessary.

Add in a test for this condition. Verified it fails without the fix.

-[Download latest release](https://github.com/mikefarah/yaml/releases/latest)
 
-or alternatively install using go get:
+a lightweight and portable command-line YAML processor
+
+The aim of the project is to be the [jq](https://github.com/stedolan/jq) or sed of yaml files.
+
+## New version!
+V3 is officially out - if you've been using v2 and want/need to upgrade, checkout the [upgrade guide](https://mikefarah.gitbook.io/yq/upgrading-from-v2).
+
+## Install
+
+### Download the latest binary
+
+[Here](https://github.com/mikefarah/yq/releases/latest)
+
+### On MacOS:
 ```
-go get github.com/mikefarah/yaml
+brew install yq
+```
+### On Ubuntu and other Linux distros supporting `snap` packages:
+```
+snap install yq
 ```
 
-## Read examples
+#### Snap notes
+`yq` installs with with [_strict confinement_](https://docs.snapcraft.io/snap-confinement/6233) in snap, this means it doesn't have direct access to root files. To read root files you can:
+
 ```
-yaml r <yaml file> <path>
+sudo cat /etc/myfile | yq r - a.path
 ```
 
-### Basic
-Given a sample.yaml file of:
-```yaml
-b:
-  c: 2
+And to write to a root file you can either use [sponge](https://linux.die.net/man/1/sponge):
 ```
-then
+sudo cat /etc/myfile | yq w - a.path value | sudo sponge /etc/myfile
+```
+or write to a temporary file:
+```
+sudo cat /etc/myfile | yq w - a.path value | sudo tee /etc/myfile.tmp
+sudo mv /etc/myfile.tmp /etc/myfile
+rm /etc/myfile.tmp
+```
+
+### On Ubuntu 16.04 or higher from Debian package:
+```
+sudo add-apt-repository ppa:rmescandon/yq
+sudo apt update
+sudo apt install yq -y
+```
+### Go Get:
+```
+GO111MODULE=on go get github.com/mikefarah/yq/v3
+```
+
+## Run with Docker
+
+Oneshot use:
+
 ```bash
-yaml r sample.yaml b.c
+docker run --rm -v ${PWD}:/workdir mikefarah/yq yq [flags] <command> FILE...
 ```
-will output the value of '2'.
 
-### Reading from STDIN
-Given a sample.yaml file of:
+Run commands interactively:
+
 ```bash
-cat sample.yaml | yaml r - b.c
+docker run --rm -it -v ${PWD}:/workdir mikefarah/yq sh
 ```
-will output the value of '2'.
 
-### Splat
-Given a sample.yaml file of:
-```yaml
----
-bob:
-  item1:
-    cats: bananas
-  item2:
-    cats: apples
-```
-then
+It can be useful to have a bash function to avoid typing the whole docker command:
+
 ```bash
-yaml r sample.yaml bob.*.cats
-```
-will output
-```yaml
-- bananas
-- apples
+yq() {
+  docker run --rm -i -v ${PWD}:/workdir mikefarah/yq yq $@
+}
 ```
 
-### Handling '.' in the yaml key
-Given a sample.yaml file of:
-```yaml
-b.x:
-  c: 2
-```
-then
-```bash
-yaml r sample.yaml \"b.x\".c
-```
-will output the value of '2'.

Upgrade Notes

@@ -0,0 +1,74 @@
+
+Major release! Upgraded underlying yaml parser, re-written majority of yq. This has brought on a number of features that have been in demand for a while (see below).
+
+This is in beta and needs some community feedback and testing :)
+
+# New Features
+  - Keeps yaml comments and formatting, can specify yaml tags when updating. https://github.com/mikefarah/yq/issues/19, https://github.com/mikefarah/yq/issues/169, https://github.com/mikefarah/yq/issues/107, https://github.com/mikefarah/yq/issues/171, https://github.com/mikefarah/yq/issues/245, https://github.com/mikefarah/yq/issues/303,https://github.com/mikefarah/yq/issues/308,https://github.com/mikefarah/yq/issues/314
+  - Handles anchors!  https://github.com/mikefarah/yq/issues/310, https://github.com/mikefarah/yq/issues/178
+  - Can print out matching paths and values when splatting https://github.com/mikefarah/yq/issues/20
+  - JSON output works for all commands! Yaml files with multiple documents are printed out as one JSON document per line. 
+  - Deep splat (**) to match arbitrary paths
+
+
+# Breaking changes
+
+## Update scripts file format has changed to be more powerful. 
+Comments can be added, and delete commands have been introduced.
+
+Before:
+```yaml
+b.e[+].name: Mike Farah
+```
+
+After:
+```yaml
+- command: update 
+  path: b.e[+].thing
+  value:
+    #great 
+    things: frog # wow!
+- command: delete
+  path: b.d
+```
+
+https://github.com/mikefarah/yq/issues/305
+
+## Reading and splatting, matching results are printed once per line.
+  e.g:
+
+```json
+parent:
+  childA: 
+    no: matches here
+  childB:
+    there: matches
+    hi: no match
+    there2: also matches
+```
+
+```bash
+yq r sample.yaml 'parent.*.there*'
+```
+
+old
+```yaml
+- null
+- - matches
+  - also matches
+```
+
+new
+```yaml
+matches
+also matches
+```
+
+and you can print the matching paths:
+
+yq r --printMode pv sample.yaml 'parent.*.there*'
+
+```yaml
+parent.childB.there: matches
+parent.childB.there2: also matches
+```
