* fix: byte-order handling for structured dtypes in the bytes codec The bytes codec neither byte-swapped structured-dtype fields to its configured endian on encode (numpy reports byteorder '|' for void dtypes, so the top-level byteorder comparison never detected a mismatch) nor honored its endian when decoding, silently corrupting any structured data whose field byte order differed from the stored one (e.g. virtual references to external big-endian data). Encode now detects byte-order mismatches by comparing full dtypes via newbyteorder, and decode reinterprets raw bytes in the stored byte order before converting to the data type's declared byte order, so the stored layout (codec state) and the in-memory layout (array data type) are independent. Closes zarr-developers#4141 Assisted-by: ClaudeCode:claude-fable-5 * test: fold structured byte-order cases into existing bytes codec tests Extend test_endian's parametrization with structured dtypes and test_bytes_codec_sync_roundtrip with endian/dtype parametrization plus stored-layout and decoded-dtype assertions, instead of adding parallel test functions for the same properties. Assisted-by: ClaudeCode:claude-fable-5 * refactor: rename stored_dtype to view_dtype in BytesCodec decode The variable is the dtype used to view the raw chunk bytes (byte order from the codec's endian configuration), not a property of the stored data or of the returned buffer, which always carries the array's declared dtype. Assisted-by: ClaudeCode:claude-fable-5 * docs: note that the decode-side byte-order conversion copies the chunk Assisted-by: ClaudeCode:claude-fable-5

Add missing changelog fragments for zarr-developers#3955 (datetime64/timedelta64 V3 metadata types), zarr-developers#3966 (writes to 0-dimensional sharded arrays), and the public alias renames that accompanied the zarr-developers#3963/zarr-developers#3968 enum deprecations, then build the 3.3.0 release notes with towncrier, consuming all fragments accumulated since v3.2.1.

Adds a development blog to the documentation site with a 3.3.0 release post covering the FusedCodecPipeline and sharded partial-read coalescing, plus two runnable examples referenced by the post (examples/codec_pipeline_performance, examples/sharding_coalescing). Compiles every pending changelog fragment into a single 3.3.0 release notes section dated 2026-07-30, merging it with the section compiled earlier in zarr-developers#4148, and empties changes/ — making this commit suitable to tag as v3.3.0.

This PR prepares the release notes for our next release. Claude's text is below

Prepares the release notes for 3.3.0, superseding #3992 (which was built on May 20 as "3.2.2" and predates most of the changes in this release).
Versioning rationale: per the versioning policy in the contributing guide, patch releases must contain no breaking or behavior changes. This release includes new features (Store.get_ranges, FusedCodecPipeline, subchunk_write_order, sharding read-coalescing config), deprecations that emit warnings (Blosc/Endian/index-location enums), intentional behavior changes (strict chunk validation from #3899, BytesCodec.from_dict endian handling from #3417), and a raised typing_extensions floor — so a minor bump to 3.3.0.
