Arvo 420 K

Vere 1.3

This release includes a high priority fix for a bug in MacOS builds.
Other platforms are unaffected.

Additionally, it brings performance improvements to u3 (the nock runtime),
and fixes some small bugs in urbit-king (the i/o process) and vere
(the other i/o process).

- LMDB syncing on MacOS

Urbit uses the LMDB embedded database to store its event log.
LMDB is a fast, small, durable, and safe database, highly regarded
and used by many projects. However, it does not make special
accommodations for the unusual file-syncing semantics of MacOS.
In some circumstances, MacOS (and therefore LMDB) may report that
a transaction has been synced to disk, but then be missing the data
(and therefore corrupted) after a kernel crash (or maybe loss of power).
(This is the issue of `fsync()` vs `fcntl(F_FULLFSYNC)`.)
We've patched LMDB to use the more reliable mechanism on MacOS.
Both urbit and urbit-king were affected.

We've been using LMDB for a couple years, many of us on MacOS.
Until recently, we have not had (or heard of) any issues. But
a handful of pilots (3 or 4) have reported crashes on startup,
and we have found their event logs to be corrupted. We've
added a command to help diagnose this issue:

    urbit db-info path-to-pier

This prints various statics about the event log, and warns if it
discovers a mismatch between the size of the file and the size
implied by the database metadata.

- u3 changes

This release adds jets for the planet un/scrambler, accelerating
print and parsing of @p around 40x. It also includes minor
improvements to the atom comparison gates (+gth, +lth, &c).

Additionally there are fixes to the nock bytecode compilation
(opcode %9 with axis 1), and corrections to jet mismatches
with the same atom comparison gates. These were all long-tail
correctness issues -- none of them were ever encountered in practice.

- urbit-king changes

This release plugs a space leak in urbit-king, and requests more
file descriptors from the OS, fixing an issue where the http
server could hang.

It also fixes a precision bug in construction of urbit timestamps,
which false implied the existence of a "femtosecond clock" in urbit-king.

- vere changes

This release adds the ability to bind the http server to a specific
ip address (via the `-b` argument), and fixes a longstanding bug
in %clay/unix sync (wherein changes that failed to |commit were
ignored by subsequent commits).

urbit-os-v2.49

This release will be pushed to the network as an over-the-air update.

Breaking changes:
- The graph-update and metadata-update have been upgraded, with corresponding
new marks

Release notes:

- Adds the ability to link to chat messages, notes, links, and comments, and
jump to them across the interface. These permalinks can also be added to
collections and shared as links outside of Urbit (if the recipient, too, has
Landscape). Permalinks also allow people to automatically join groups and
channels if both are public, jumping straight to the content.

- Adds a protocol handler, web+urbitgraph://, on Chrome and Firefox over HTTPS,
that allows the browser to redirect permalinks to your Landscape session.

- Adds a new module, the group feed, as an option for each group. Hosts, admins
and members can be permissioned to a group feed, posting and replying in
threaded conversations.
