SPRING BATCH GAINS LEGACY EXCEL STREAMING, SECURITY PATCHES ROLL ACROSS STACK

By RepoJournal · Filed · About Spring

Spring Batch Extensions shipped a low-memory streaming reader for legacy .xls files, while PostgreSQL security update lands across session management.

Spring Batch Extensions added `StreamingXlsItemReader<T>` [1] to handle binary BIFF8/HSSF files with the same memory efficiency as its existing XLSX counterpart, inheriting all configuration, mapping, and restart behavior from the proven `AbstractExcelItemReader` abstraction. The new reader plugs a gap for teams still dealing with legacy Excel workbooks in production batch jobs. Meanwhile, PostgreSQL 42.7.12 shipped a security fix [2] addressing CVE-2024-54291, a silent channel-binding downgrade vulnerability in SCRAM-SHA-256-PLUS authentication that Spring Session deployments should patch immediately. Spring Security bumped Hibernate ORM to 7.4.3.Final [3] and HttpClient to 5.6.2 [4], both maintenance releases bringing stability improvements. Spring Boot cleaned up unnecessary nullable annotations on local array variables [5], a small but signal change indicating tighter null-safety discipline across the framework.
