Released on 2026-05-29.

• Replaced the core interpreter with a brand-new rewrite that has been
  designed, from the ground up, to target efficient bytecode compilation.
  In some ad-hoc compute-heavy benchmarks, this shows a 7x performance
  improvement.

• Added support for DECLARE FUNCTION and DECLARE SUB, which are now
  needed by the compiler in client code to forward-declare user-defined
  functions and subroutines.

• Running RUN in a multi-statement line no longer executes trailing
  statements if the program aborts with END and a non-zero exit code.
  This can be seen as a regression from the core rewrite, but it should
  impact so few scenarios that it'll be fixed later.

• Calling CLEAR from within a SUB or GOSUB currently terminates
  execution of the whole program instead of continuing after the clear.
  This can be seen as a regression from the core rewrite, but it should
  impact so few scenarios that it'll be fixed later and the behavior of
  this scenario is to be determined.

• CTRL+C cannot be caught as a key anymore during INPUT or INKEY calls.
  This is a side-effect of the core changes but I think is the more
  appropriate behavior.

• Changed ON ERROR GOTO semantics so that a handler is single-use until
  another ON ERROR statement re-arms it. This prevents recursive error
  handling loops after failures such as call stack overflows.

• Fixed handling of Ctrl-based keybindings in the SDL console so that
  CTRL+<key> work even when extra modifier flags are active.

• Fixed EOF handling in the terminal console so that pressing CTRL+D
  during INPUT aborts the running command but does not immediately exit
  the REPL.

• Improved responsiveness and scheduling in the web interface by aligning
  paint-related yields with browser frame rendering and by using
  a MessageChannel for fairness-only host yields.

• Because the new core has been AGPLv3+ licensed, the rest of the project
  has switched to this license as well.
