Make a new release

[skx]

There have been a whole bunch of changes, albeit at reduced speed, so time for a release.

I could look at other lisps forever, so I will continue doing that in the background and leave #115 open for a while longer.

• e.g. Looked at "Ale" and saw this:
  • Equality in Ale ≠ Equality in Go - https://www.ale-lang.org/ffi/
  • Which lead to me fixing my implementation in When converting hashes to strings, sort their keys first. #127.

• Updated the LSP support to only calculate possible completions once.
  • Since we only complete on the standard library this can't change.
  • Reported in Improve LSP #111, resolved in Cache LSP completions. #112.
• Updated our CI process to run the lisp-specific test-cases on PRs
  • Implemented in More thorough CI testing. #113
• Added string<, string=, and similar methods.
  • Implemented in Added sort-by, string=, and string< #116.
• Added flexible sort-by method
  • Also implemented in Added sort-by, string=, and string< #116.
• Implemented cos, sin, and tan, as well as variants along with pi.
  • Implemented in Implement trig. functions. #117.
• Added extra argument testing to (random) and (base)
  • With test-cases and fuzz-testing for more fixes.
  • Implemented in More fixes. #118.
• Fixed crashes with empty special forms, e.g. "(print (do))" and (print (let*())).
  • Fuzzing now looks good, though of course it is impossible to say:
    • fuzz: elapsed: 19h4m10s, execs: 5319853 (303/sec), new interesting: 492 (total: 4095)
    • fuzz: elapsed: 19h4m12s, execs: 5319918 (40/sec), new interesting: 492 (total: 4095)
• Allow loading a file with "(require 'foo)"
  • This will load foo.yal, and return nil if that file is not present.
  • Reported in Allow "require" or "import" #114, and implemented in Allow loading a file with (require 'foo) #119.
• Added stack:push, stack:pop, etc.
  • Implemented in Add a set of stack primitives. #120.
• Added a config-package, holding helpers for STDIN/STDOUT.
  • These are used by (read) and (print)
  • Implemented in Allow I/O operations to have a level of indirection. #123, after a broken attempt in Renamed the builtin-signature, again. #121.
  • Added STDERR and a -debug flag in Added -debug flag, writing to STDERR. #125.
• Added (version).
  • Reported in Add (version) #122, implemented in Added (version) primitive to REPL #124.
• Added hash/digest functions in Add md5/sha1/sha256 digest functions. #126
  • (md5), (sha1), and (sha256).
• Hashes are converted to strings with their keys sorted.
  • Implemented in When converting hashes to strings, sort their keys first. #127
  • This allows the following code to return "true", as expected:
    • (eq { :name "Steve" :surname "Kemp" } { :surname "Kemp" :name "Steve" })
