on GitHub

CHANGES:

• Update JS reserved keywords
  (#1338)
• Remove errors for bs.* and non-namespaced attributes
  (#1348)
  • These attributes haven't been supported since Melange v4, and deprecated
    before that
  • erroring on e.g. attributes like @as prevents e.g. universal libraries
    that want to use PPXes supporting @as with native semantics.
• remove @mel.splice error
  (#1350)
  • @mel.splice has been removed in earlier Melange versions and it has
    been producing errors for the last 2 versions. Since ecosystem libraries
    have been keeping up to date with Melange versions, after this change, it
    will be silently ignored.
• allow @mel.as "constant" and @mel.this to coexist -- marking the constant
  argument as the instance / self argument
  (#1353)
• JS generation: improve indentation of new blocks
  (#1360)
• JS generation: improve indentation of blocks with array/string/char accesses
  (#1361)
• runtime: improve the runtime for exceptions / extensible variants to account
  for sharing extensions across contexts
  (#1326)
  • This change moves the exception runtime from a global counter to a
    counter per module. This impacts calls to Printexc.exn_slot_id and
    Printexc.exn_slot_name, which would previously return the global
    identifier at exception creation, and will now return the module-local
    runtime identifier.
• build: fix Melange build on dune profiles other than dev / release
  (#1365)
• core, runtime: optimize throwing errors in Melange, fix re-throwing
  regression and throwing JS values
  (#1362)
• runtime: add Js.Fetch module with types for fetch in JS
  (#1343)
• runtime: add Js.ReadableStream module to unify around its type in community
  libraries (#1344)
• runtime: add Js.WritableStream
  (#1367)
