The server now automatically checks buffer boundaries before accessing the next character, preventing potential parsing errors + +[`Bug#37602657`](https://github.com/mysql/mysql-server/commit/f97c71a): In certain scenarios, secondary indexes on virtual columns can become misaligned with the clustered index data. The fix is when creating update vectors for secondary index updates involving virtual columns, use the field number (field_no) instead of the virtual column position. + +[`Bug#37994397`](https://github.com/mysql/mysql-server/commit/2c6e56c3bd4): MySQL's InnoDB buffer pool, which can be configured across multiple instances and chunks, previously risked silent allocation failures when creating chunk lists for very large buffer pools. The server now explicitly checks and handles allocation failures for the chunk list, ensuring robust memory management during buffer pool initialization. + +[`Bug#37792010`](https://github.com/mysql/mysql-server/commit/e12a310892d): In MySQL 5.7, full-text search (FTS) configuration table columns lacked proper type initialization, which could potentially cause a server crash when concurrent queries accessed the INFORMATION_SCHEMA.INNODB_LOCKS table under specific rare conditions. The fix ensures these internal VARCHAR columns are initialized with valid type information, preventing potential crashes during concurrent table access. + +## Additional Resources + +- [Install Percona Server for MySQL](../installation/install-eol.md) +- [Percona Server for MySQL GitHub Repository](https://github.com/percona/percona-server) +- [Contribute to the Documentation](https://docs.percona.com) +- [Percona Training – Start Learning Now](https://www.percona.com/training) diff --git a/docs/release-notes/release-notes_index.md b/docs/release-notes/release-notes_index.md index 7440cdf9899..2fbb25eace2 100644 --- a/docs/release-notes/release-notes_index.md +++ b/docs/release-notes/release-notes_index.md @@ -1,5 +1,7 @@ # Percona Server for MySQL 5.7 release notes index +* [Percona Server for MySQL 5.7.44-56 (2025-11-27)](5.7.44-56.md) + * [Percona Server for MySQL 5.7.44-55 (2025-09-25)](5.7.44-55.md) * [Percona Server for MySQL 5.7.44-54 (2025-05-26)](5.7.44-54.md) diff --git a/mkdocs-base.yml b/mkdocs-base.yml index 00a777ef2c4..10ba2d5af88 100644 --- a/mkdocs-base.yml +++ b/mkdocs-base.yml @@ -102,7 +102,7 @@ plugins: with-pdf: # https://github.com/orzih/mkdocs-with-pdf output_path: "_pdf/PerconaServer-5.7.pdf" cover_title: "Percona Server Documentation" - cover_subtitle: 5.7.44-54 (2025-05-26) + cover_subtitle: 5.7.44-56 (2025-11-27) author: "Percona Technical Documentation Team" cover_logo: docs/_static/Percona_Logo_Color.png debug_html: false @@ -240,6 +240,7 @@ nav: - tokudb/removing_tokudb.md - Release notes: - Release notes index: release-notes/release-notes_index.md + - release-notes/5.7.44-56.md - release-notes/5.7.44-55.md - release-notes/5.7.44-54.md - release-notes/5.7.44-53.md diff --git a/variables.yml b/variables.yml index ad870873479..eaacaf86233 100644 --- a/variables.yml +++ b/variables.yml @@ -1,8 +1,8 @@ # variables for HTML output -release: '5.7.44-55' +release: '5.7.44-56' version: '5.7' -release-date: August 20, 2025 +release-date: November 27, 2025 post: 'MySQL 5.7 Post-EOL Support from Percona' repo-post: 'ps-post-eol' eol: 'Post-EOL'
