Pi-Bolt 0.8.3 fixes updating in place on macOS and restores 0.8.1's speed on Linux and Windows. Everything else is
0.8.2.

macOS

  • A session started before an update keeps working. Updating with the installer or pi-bolt update replaces the build's
    files, and a session of 0.8.1 that was still running stopped at the end of its next command (a tool's command, or the version
    check that ends pi-bolt update, which installed 0.8.2 and then did not return). Such a session now goes on; only the
    resource usage of its commands is not reported until it is restarted.
  • If a session or a pi-bolt update stopped like that on 0.8.2: end it (Ctrl+C), and start Pi-Bolt again. 0.8.2 was installed.

Performance

  • Linux and Windows: 0.8.2's engine read some properties of the compiled code the generic way on x86-64, which made the TUI
    start and respond a few percent slower than 0.8.1. 0.8.3 reads them as 0.8.1 did.
  • The built-in Herdr extension is set up only in a Herdr pane.
  • Measured against 0.8.0 and 0.8.1 as released (interleaved runs on the same cores): startup, a headless prompt and the TUI
    (time to interactive, five turns) are the same within 1% on Linux x86-64 and macOS, with a little less memory.

Plugins

  • scripts/build-pi.sh: when the compiler stops the build (a plugin's module over the size limit, say), the build shows the end
    of what the compiler printed and where all of it is, rather than nothing (#8).

Engine

  • Typed fields (useAOTTypedFields, off in every build) are off on CPUs other than ARM64, whose compiled accesses do not check
    them; the table of types is as in 0.8.1.

The runtimes
