Patch Changes

• #1942 c8fe1d4 - For minified class fields on classes in lit libraries, added prefix to stable properties to avoid collisions with user properties.

• #1959 6938995 - Changed prefix used for minifying class field names on lit libraries to stay within ASCII subset, to avoid needing to explicitly set the charset for scripts in some browsers.

• #1964 f43b811 - Don't publish src/ to npm.

• Updated dependencies [ff0d1556, 5768cc60, 69389958, 5fabe2b5, 52a47c7e, 5fabe2b5, 5fabe2b5, 5fabe2b5, f05be301, 5fabe2b5, 56e8efd3, 662209c3, a791514b, 5fabe2b5]:

Major Changes

• #1959 69389958 - Changed all prefixes used for minifying object and class properties from greek
  characters to ASCII, to avoid requiring an explicit script charset on some
  browser/webview environments.

Patch Changes

• #2002 ff0d1556 - Fixes polyfill-support styling issues: styling should be fully applied by firstUpdated/update time; late added styles are now retained (matching Lit1 behavior)

• #2034 5768cc60 - Reverts the change in Lit 2 to pause ReactiveElement's update cycle while the element is disconnected. The update cycle for elements will now run while disconnected as in Lit 1, however AsyncDirectives must now check the this.isConnected flag during update to ensure that e.g. subscriptions that could lead to memory leaks are not made when AsyncDirectives update while disconnected.

• #1942 c8fe1d4 - For minified class fields on classes in lit libraries, added prefix to stable properties to avoid collisions with user properties.

• #2041 52a47c7e - Remove some unnecessary internal type declarations.

• #1959 6938995 - Changed prefix used for minifying class field names on lit libraries to stay within ASCII subset, to avoid needing to explicitly set the charset for scripts in some browsers.

• #1937 3663f09 - Re-export PropertyPart from 'directive.ts'

• #1964 f43b811 - Don't publish src/ to npm.

• #1991 f05be301 - Fixed bug where Template.createElement was not patchable by polyfill-support when compiled using closure compiler, leading to incorrect style scoping.

• #2016 e6dc6a7 - Clean up internal TypeScript types

• #1990 56e8efd3 - Fixed an error thrown when an empty <style></style> tag is rendered while using the @apply shim under native Shadow DOM.

• #2044 662209c3 - Improves disconnection handling for first-party AsyncDirectives (until, asyncAppend, asyncReplace) so that the directive (and any DOM associated with it) can be garbage collected before any promises they are awaiting resolve.

• #1972 a791514b - Properties that must remain unminified are now compatible with build tools other than rollup/terser.

• #2050 8758e06 - Fix syntax highlighting in some documentation examples
