• agno-agi/agno: Fixed silent CSV row loss during asynchronous pagination by applying header skipping only to the first page. (PR #9995) Identified silent text loss in grouped PowerPoint shapes, traced the cause to missing traversal of nested shapes, and provided a minimal reproduction used to verify the upstream fix. (Issue #9999)
• edwardkim/rhwp: Fixed keyboard activation failures in text and highlight color controls by separating selection-preserving mousedown handling from standard click activation. (PR #6786)
• google/adk-docs: Clarified that Python session-history filters limit the loaded event view while preserving stored history when new events are appended. (PR #2244)
• google/adk-python: Fixed empty-text artifacts being treated as missing by removing an incorrect rejection in the shared in-memory load path. (PR #7072) Fixed file artifact creation timestamps changing on every metadata read by preserving persisted timestamps in the shared conversion helper. (PR #7113) Prevented artifact paths from colliding with internal version storage by rejecting reserved filenames before writing. (PR #7122) Restored oldest-first Redis session lists by sorting on update time with deterministic user and session ID tie-breakers. (PR #7124) Fixed Redis session history loss after filtered reads by reloading stored events in a retryable transaction before appending. (PR #7140)
• i-am-bee/beeai-framework: Fixed incorrect GrepTool search results for leading-hyphen patterns by separating ripgrep options from search arguments. (PR #1660) Prevented GrepTool from consuming or waiting on host input by isolating ripgrep's stdin with DEVNULL. (PR #1661) Fixed default file, shell and console I/O failures in new execution contexts by providing local fallbacks when reading ContextVars. (PR #1662) Fixed mutations leaking between SlidingCache clones by isolating cache state while preserving cached value references. (PR #1683) Fixed lost middleware callbacks and shared cache state when cloning file and shell tools by preserving callbacks and cloning each tool's cache. (PR #1706)
• pandas-dev/pandas: Fixed empty cells left by hidden indexes and columns in Typst table output by filtering hidden cells while preserving sparse MultiIndex labels. (PR #68991)
• PrefectHQ/fastmcp: Fixed stale tool schemas in cached BM25 searches by resolving ranked tool names against the current catalog. (PR #5153)
• ratatui/ratatui: Fixed a BufferDiff rendering bug that left stale background and underline styles on wide Unicode glyphs by clearing trailing cells before repainting. (PR #2743)
