### Time / configuration / data interchange

- "application" for declaring application metadata (notably for SBOMs)
- "character_sets" for converting between character codes and bytes plus =
charset metadata =20

SHA256, CRC32, and others)
- "toml" for parsing and generating TOML v1.0.0 files =20
- "tzif" for parsing TZif files, persisting parsed snapshots, and =
querying UTC offsets, DST, and abbreviations =20
- "dates_tz" for linking "dates" and "tzif" to support zone-aware =
date-time conversions =20
- "mime_types" for mapping file extensions, file names, and URL-like =
resources to MIME types and content encodings =20

### Data structures / collections

- "dictionaries": added a 2-3 tree implementation contributed by Michael =
T. Richter =20

## Changed libraries by category/area

- "iso8601" contribution: added "time_string/3" and =
"date_time_string/3", extended "interval_string/2", and added support =
for comma as a fractional separator =20

### Coordination / networking

- "linda": reorganized around "linda_server" and "linda_client" =
categories, while keeping a backward-compatible default object =20
- "linda": clients can now connect to multiple servers and define =
aliases for server connections =20
- "linda": improved connection error reporting plus fixes for shutdown, =
tuple handling, synchronization, and matching behavior =20
- "sockets": added "server_open/4" for starting a server on a specific =
interface=20

### Validation / web / identifiers / types

## Non-library notable changes

- Compiler/runtime: added a new "force" target to "logtalk_make/1", =
added the "term_position(Term)" load-context key, fixed entity operator =
leakage from included files, improved handling of multifile/dynamic =
predicates on some backends, and protected key load/compile/runtime =
update operations with mutexes on multi-threaded backends =20
- Documentation: added notes on limitations when using conditional =
compilation directives in included files and fixed missing documentation =
for the "info/1" entity property =20
