2021/7/30 Workers Runtime Release Notes

Changes this week:

  • Fixed a hang in Durable Objects when reading more than 16MB of data at once (for example, with a large list() operation).
  • Added a new compatibility flag html_rewriter_treats_esi_include_as_void_tag which causes HTMLRewriter to treat <esi:include> and <esi:comment> as void tags, such that they are considered to have neither an end tag nor nested content. To opt a worker into the new behavior, you must use wrangler 1.19.0 or newer and specify the flag in wrangler.toml. See the wrangler compatibility flag notes for details.
