Recordings made with asciinema CLI 3.0 or later may embed original terminal theme, which is used by the player when available.

Before this release the only way to let the player use the embedded theme automatically was not specifying the theme option when initializing the player. When the theme option was not used, the player favored the embedded theme, falling back to asciinema theme. There was no way to specify "use the original theme when available, fall back to monokai".

This release adds the ability to specify the above wish as { theme: "auto/monokai" }. You can use any built-in theme, e.g. { theme: "auto/dracula" }, and the player will use Dracula theme if the original theme was not captured at the time of recording.

To always use a specific theme regardless of the presence of the original theme in a recording file, use { theme: "<theme-name>" }, e.g. { theme: "dracula" }.

Default value of the theme option (when one not specified) is now auto/asciinema.

Notable changes:

greatly improved rendering (position, alignment, accuracy) of ascii drawing, block elements, braille patterns and Powerline triangle symbols
fixed alignment of double-width chars (such as CJK, emoji)
new adaptive algorithm for buffering in live (websocket) driver, ensuring smooth playback on high-latency or high-jitter network connections
minor rendering performance improvement via UI updates batching
improved visibility of play button's drop shadow for themes with light background
code refactorings and cleanup
