0.4.0 release

[arjunattam]

native host application

• fix blocking during message passing - we should be able to implement simple concurrency since we have callback maps already. to test: add sleep to info message and send multiple messages
• auto updating
• define location for cloning repos
• use theia language server?
• language server is running even after the tab has been closed

content script

• show not ready state in the hover; don't send native message if not ready
• show error for no auth (private repos); this seems to be working if system git has auth -> verify
• show something helpful when language is not supported
• show something when native host update is available
• test for PRs: I don't think we are initializing the base sha properly
• git clone progress
• rate limited API error

onboarding

• repo readme and change log update
• add post install page to assist native host installation

misc

• add license

for auto-update, we are unable to get $PATH inside the updater child_process. to fix this, perhaps we could avoid the pkg dependency on native host side and run a .js file like in this example:
