2d78bff120 feat: pass vector column name to remote backend (#710)
pass vector column name to remote as well.

`vector_column` is already part of `Query` just declearing it as part to
`remote.VectorQuery` as well

144b3b5d83 ci: fix broken npm publication (#704)
Most recent release failed because `release` depends on `node-macos`,
but we renamed `node-macos` to `node-macos-{x86,arm64}`. This fixes that
by consolidating them back to a single `node-macos` job, which also has
the side effect of making the file shorter.

d087e7891d feat(python): add update query support for Python (#654)
Closes #69

Will not pass until https://github.com/lancedb/lance/pull/1585 is
released

Chang She
098e397cf0 feat: LocalTable for vectordb now supports filters without vector search (#693)
Note this currently the filter/where is only implemented for LocalTable
so that it requires an explicit cast to "enable" (see new unit test).
The alternative is to add it to the Table interface, but since it's not
available on RemoteTable this may cause some user experience issues.

693091db29 chore(python): Reduce posthog event count (#661)
- Register open_table as event 
- Because we're dropping 'seach' event currently, changed the name to
'search_table' and introduced throttling
- Throttled events will be counted once per time batch so that the user
is registered but event count doesn't go up by a lot

244b6919cc chore: Use m1 runner for npm publish (#687)
We had some build issues with npm publish for cross-compiling arm64
macos on an x86 macos runner. Switching to m1 runner for now until
someone has time to deal with the feature flags.

follow-up tracked here: #688

EXPERIMENTAL: Update rows in the table (not threadsafe).
This can be used to update zero to all rows depending on how many
rows match the where clause.
Parameters
----------
where: str
where: str, optional
The SQL where clause to use when updating rows. For example, 'x = 2'
or 'x IN (1, 2, 3)'. The filter must not be empty, or it will error.
values: dict
values: dict, optional
The values to update. The keys are the column names and the values
are the values to set.
values_sql: dict, optional
The values to update, expressed as SQL expression strings. These can
reference existing columns. For example, {"x": "x + 1"} will increment
the x column by 1.
Examples
--------
>>> import lancedb
