+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at mikefarah@gmail.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,

Upgrade Notes

@@ -1,74 +0,0 @@
-
-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
-```
