Latest Windows release
v0.6.35 — 2026-11-04
Changes
- Reduced resident memory: the input predictor and correction worker share immutable dictionaries. Compact indexed blocks retain all 140,939 bundled words and their frequency ranks while reducing the EN/UK/RU lookup payload from approximately 3.06 MiB per copy to 0.90 MiB shared. Custom UTF-8 dictionary files, duplicate handling, frequency limits and personal dictionaries remain compatible.
- Closing clipboard history releases its duplicate row list and Windows list strings, retains selection/scroll identifiers for reopening, and rejects late search results and timers. Preview caches now have payload budgets of 1 MiB for thumbnails and 256 KiB for formatted text, plus the existing item-count limit. Visible entries are retained even if an unusually large viewport exceeds a budget.
- PNG decoding reads the existing input buffer without making another full PNG copy. DIB decoding allocates its temporary BMP buffer once at the required size.
- Idle maintenance releases diagnostic context older than 30 seconds and expired Undo text after its existing two-minute eligibility window, without interrupting an active operation. Completed sync buffers are released on success, failure and stale responses; unresolved conflicts remain available.
- No shortcut, default, on-disk history format or screenshot-editing behavior changed. The v0.6.34 four-direction movement cursors remain included.
Validation
The full build.ps1 -Stage -Test suite covers complete bundled dictionary word/rank equivalence, malformed/custom dictionary boundaries, 105 sync checks, shared wheel batching, 304 native regressions, 559 input/UI checks, screenshot editor UI and PNG saving, isolated screenshot registration, 48 updater regressions and updater progress UI checks. Cache assertions now run once outside the exception helper rather than being repeated inside it. All three executable versions and all 12 package manifest file sizes/SHA-256 hashes were verified; no personal data is packaged.
Controlled local measurements of the final dictionary step, after equal restart/wait periods with three dictionaries enabled, reduced private resident memory from 7.08 to 4.65 MiB and private committed memory from 8.34 to 5.70 MiB. These compare consecutive development builds, not the published v0.6.34 with the full cumulative change. Randomized lookup tests were approximately 20% faster. Results depend on settings, workload, Windows and allocator state; these are not fixed memory limits. The 0.90 MiB dictionary figure excludes process/allocator overhead.
Upgrade
Choose Update in the tray menu. Legacy v0.3.0–v0.4.1 clients first receive the v0.4.2 compatibility bridge, then the current full release. v0.2.3 and earlier require manual installation.
For manual installation, exit KSwitcher, close screenshot editors and extract the entire ZIP into its installation folder. Keep personal data/ and customized dictionaries.
Download KSwitcher-win-x64.zip with SHA256SUMS.txt. Keep all three executables together. The package contains no personal settings, credentials or clipboard history.
Publish stable release-vX.Y.Z tags matching the executable version. Keep v0.4.2 as the last legacy tag.
