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..94fe6001677 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 5.7.44-55 (2025-11-25)](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..5933a2d4dc1 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 (2025-11-25) 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..b451b58d5ed 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 25, 2025 post: 'MySQL 5.7 Post-EOL Support from Percona' repo-post: 'ps-post-eol' eol: 'Post-EOL' From d864f0cafb39b59bac648fdd984df6e0227a3363 Mon Sep 17 00:00:00 2001 From: Alina Derkach Date: Wed, 26 Nov 2025 15:24:52 +0100 Subject: [PATCH 2/5] Update 5.7.44-56.md --- docs/release-notes/5.7.44-56.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/docs/release-notes/5.7.44-56.md b/docs/release-notes/5.7.44-56.md index 8c8312d132e..dad66dc3a2b 100644 --- a/docs/release-notes/5.7.44-56.md +++ b/docs/release-notes/5.7.44-56.md @@ -1,4 +1,4 @@ -# Percona Server for MySQL 5.7.44-56 (2025-11-25) +# Percona Server for MySQL 5.7.44-56 (2025-11-27) --8<--- "eol.release.md" From 7380db0e6d2e28b32cdeb0619273e86a71b67772 Mon Sep 17 00:00:00 2001 From: Alina Derkach Date: Wed, 26 Nov 2025 15:25:27 +0100 Subject: [PATCH 3/5] Update release-notes_index.md --- docs/release-notes/release-notes_index.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/docs/release-notes/release-notes_index.md b/docs/release-notes/release-notes_index.md index 94fe6001677..2fbb25eace2 100644 --- a/docs/release-notes/release-notes_index.md +++ b/docs/release-notes/release-notes_index.md @@ -1,6 +1,6 @@ # Percona Server for MySQL 5.7 release notes index -* [Percona Server for MySQL 5.7.44-55 (2025-11-25)](5.7.44-56.md) +* [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) From c81f47ee38fa2e2cc49e9ffec483dd9809762da5 Mon Sep 17 00:00:00 2001 From: Alina Derkach Date: Wed, 26 Nov 2025 15:26:19 +0100 Subject: [PATCH 4/5] Update mkdocs-base.yml --- mkdocs-base.yml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mkdocs-base.yml b/mkdocs-base.yml index 5933a2d4dc1..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: 5.7.44-56 (2025-11-25) + 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 From ed8f784376a9b793588ea3e0df95aeb56ae07053 Mon Sep 17 00:00:00 2001 From: Alina Derkach Date: Wed, 26 Nov 2025 15:26:39 +0100 Subject: [PATCH 5/5] Update variables.yml --- variables.yml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/variables.yml b/variables.yml index b451b58d5ed..eaacaf86233 100644 --- a/variables.yml +++ b/variables.yml @@ -2,7 +2,7 @@ release: '5.7.44-56' version: '5.7' -release-date: November 25, 2025 +release-date: November 27, 2025 post: 'MySQL 5.7 Post-EOL Support from Percona' repo-post: 'ps-post-eol' eol: 'Post-EOL'
