Fixes ^^^^^ * Reverted "Improved performance of updating inverted indexes in the worst case". It had reported error when key has multibyte character. This change was included in 6.1.2. * [:ref:`token-regexp`] Fixed a bug that `\\A${ONE_CHARACTER}\\z` returns all one character values. .. _release-6-1-2: Release 6.1.2 - 2016-12-31 -------------------------- Improvements ^^^^^^^^^^^^ * windows: Supported to bundle groonga-normalizer-mysql. * [:doc:`/reference/log`] Added description about log format with ``PID`` case. * [:doc:`/install/centos`] Improved installation procedure about recent ``groonga-release`` package. * [:doc:`/reference/commands/load`] Supported to show ``{"n_loaded_records": N}`` in response for command version 3 or later. * [:doc:`/reference/commands/load`] Supported ``--output_ids yes`` parameter for command version 3 or later. If ``--output_ids yes`` is specified, loaded record IDs(``loaded_ids``) are also returned. ID is 0 for record that is failed to add. * [:doc:`/install/others`] Added installation instruction about depended packages (Zstandard, LZ4) * Changed to use Onigmo 6.0 as regular expression library. * Marked some features as stable. * :doc:`/reference/executables/grndb` command. * :doc:`/reference/commands/request_cancel` command. * :doc:`/reference/functions/highlight_html` function. * :doc:`/reference/functions/highlight_full` function. * :doc:`/reference/functions/snippet_html` function. * [httpd] Updated bundled nginx to 1.11.8. * Improved to reduce ``AND`` search response time.

[GitHub#589] [Reported by Naoya Murakami] * [debian] Changed to use nginx log reopen feature instead of Groonga's [:doc:`/reference/commands/log_reopen`] command because log_reopen command works only for one worker. On the contrast, nginx log reopen feature works for multiple workers. * [:doc:`/reference/commands/table_copy`] Added ``table_copy`` command which copies specified table. * [:doc:`/reference/commands/column_copy`] Supported to cast A table record to B table record.
