3.6.4

This is a minor release, which improves keyboard shortcut handling.

3.6.3

This is a minor release that features a major performance bump for the embedded terminal emulator—up to 70% faster emulation in sequence parsing and virtual buffer manipulation. This leaves more CPU cycles available for smoother rendering ✨

• terminal emulation improvements (RI, VPR)
• better text reflow upon terminal resize
• fixed big play button centering
• removed redundant CSS styles

3.6.1

• implemented terminal resizing via resize events in asciicast file and SIGWINCH entries in typescript files
• added rudimentary screen-reader support (thanks @bmmcginty!)
• added Dracula theme
• changed handling of user-specified markers - they're not subject to idle time limiter anymore
• upgraded asciinema virtual terminal to latest version

The work on resize feature has been sponsored by ITLook. Thanks @boris-42 !

3.5.0

• added experimental websocket-based live streaming protocol (ALiS)
• more efficient parsing of typescript and ttyrec recordings
• improved logging
