Send & Remove PHI on Every Selected Message

fixed Various bug fixes and stability improvements

v1.0.69 October 23, 2026

Text Size & a More Responsive App

added Text size: choose Standard, Larger or Largest in Edit > Settings. Every window grows as a whole (text, buttons and spacing together), so everything stays lined up, and the change shows live in every open window.

improved HL7 Pulse keeps responding while a large file is prepared for search. Advanced Search, HL7 Statistics, the HL7 Event Timeline, Send and the other windows open straight away.

improved Long messages are shown whole in the HL7 Message panel, every row and with syntax colors.

improved A value too long for its column ends in "…" and shows in full when you point at it, instead of being cut off mid-word.

v1.0.68 October 6, 2026

HL7 Lookup, Event Timeline & HL7 Statistics Selection

added HL7 Lookup (Tools menu) is a built-in HL7 v2 reference for versions 2.1 to 2.8.1: segments, fields, data types, tables and trigger events, searchable across all versions. Right-click a segment, field or component in HL7 Elements to jump straight to it.

added In HL7 Statistics you can click a message type to narrow the whole window to it. Filter Messages then filters the message list to your selection.

added The HL7 Event Timeline can be filtered by sending facility, and hours with no messages are marked on the chart.

added Right-click an entry in the Activity Timeline and choose Replay.

added Help > About has a Third-party notices link.

improved The HL7 Event Timeline opens on an All messages line over your feed's own time span. Save Image and Copy include the chart's title and legend.

improved HL7 Statistics' volume chart matches the timeline's, and Open in HL7 Event Timeline opens it on the same hours and facilities.

improved Components are labelled with HL7's own names everywhere. HL7 Elements uses the data types from the message's own HL7 version, and Add field repetition shows a single box for simple fields.

improved Replaying from the Activity Timeline checks whether the data is already open, and tells you when steps could not be replayed.

improved Reopening a saved tab no longer shows a Cancel button, and its status line shows the message count.

improved The installer shows its progress by stage and keeps a setup log. No count in the app says "(s)" any more.

improved HL7 Statistics' CSV export is named after the folder.

changed View > Graph is now HL7 Event Timeline.

v1.0.67 September 29, 2026

HL7 Statistics, Feed Definitions & Faster Large Files

added HL7 Statistics (View > HL7 Statistics) gives you an overview of a feed: its message types, sending facilities, which segments appear and how often they repeat, and message volume by hour. You can pick one or more sending facilities to see their figures on their own, and export everything to CSV.

added Feed Definitions let you save a feed's structure and check a later feed against it. The check reports message types, segments and fields that are missing or new, and fields that are filled in noticeably less often. You manage saved definitions under Tools > Feed Definitions and can create a PDF report of any structure or comparison.

added HL7 Elements shows the data type of every field, for every HL7 version from 2.1 to 2.8.1.

added You can export the message list and Unique Values to CSV, and copy selected rows straight into a spreadsheet.

added You can type a page number to jump straight to that page. Unique Values has a filter box for finding one value among thousands.

improved Large files open much faster. Messages appear as soon as they are read while search gets ready in the background, and if you close the app first, it picks up where it left off.

improved Remove PHI covers more fields, including an MRN in PID-2, merge messages, guarantors, next of kin and employers. Each patient keeps one replacement name and set of identifiers across every message, so an anonymized feed can still be followed. Known names and identifiers are also removed from notes, comments and Z-segments. Replacement identifiers keep their original format, and removal is much faster on large files.

improved Cancel now stops every long operation, including Remove PHI, changing a field in every message and bulk deletes, and leaves your messages exactly as they were. Long operations also show their speed and time remaining.

improved You can switch to another saved server in one click. The remote folder is shown once and in full, and Save Profile remembers the folder you're in.

improved Hovering over a tab always shows where its messages came from, even after a restart.

improved Help has been checked against the app. It now has screenshots and links between topics, and search looks inside topics, not just their titles.

improved From this version on, installing an update closes HL7 Pulse by itself and reopens your tabs, unsaved changes included.

changed Delete all above, below, or all except this one now works within your search and filters, in the order the list shows. Messages the filters hide are kept.

changed Jumping back on the Activity Timeline restores the list exactly as it was: searches, message type, filters and sort.

changed Text that doesn't begin with MSH, such as a logging line, is no longer imported as a message.

v1.0.66 August 24, 2026

Bi-directional (Synchronous) Exchange

added Bi-directional (Synchronous) exchange under File > Transmission — send a query (for example a QRY) and receive the application response (for example an ADR) on the same connection. The response appears in the window as it arrives, with its acknowledgment code and control ID checked, and every captured response can be opened in a new tab.

added An optional setting, Acknowledge the response, sends an ACK back for each response received, for interfaces that expect one.

improved Send now reports a receiver that never acknowledges as a timeout instead of showing it as cancelled, and Retry on connection failure also covers connection timeouts.

fixed Various bug fixes and stability improvements

v1.0.65 August 21, 2026

Easier Send Profiles & Custom Delimiter Import

added Send window profiles are easier to manage — type a name in the Profile box and click Save (or press Enter) to create one, and use the clear button to start fresh while keeping your connection settings.

changed The Send window no longer preselects a saved profile when it opens — your last-used host and port are restored instead.

improved Files that use custom HL7 delimiters now import correctly and are handled consistently throughout the app.

Repeating Fields, Custom Delimiters & Session Reliability

fixed Various bug fixes and stability improvements

v1.0.63 July 29, 2026

Connection Status, HL7 Delimiters & Reliable Session Restore

added Remote Files and Remote Save As now always show which server you're connected to, with a status light for connected, connecting, failed, or not connected.

added MSH-2 now expands to show the message's delimiters and what each one means — read from the actual message, so unusual encodings show their real characters.

added The installer now has a What's New page highlighting each release's changes.

changed The Connect button is now disabled while you're connected. To switch to a different server, disconnect first.

fixed Various bug fixes and stability improvements

v1.0.62 July 23, 2026

Performance, Polish & Reliability

added Files opened together are now remembered as a group in Recent Files — reopen the whole set in one tab, or pick an individual file from the submenu.

changed File → Add HL7 Files now adds into the current tab when it already has messages, instead of opening a separate tab.

improved Large files are noticeably faster: adding files to a tab, removing PHI from all messages, deleting large ranges of messages, and editing a field across all messages all complete much more quickly.

improved Paging through advanced-search results is now instant, even on very large files.

improved Import progress no longer looks frozen on files with large embedded PDFs or images — the counter updates smoothly from start to finish.

improved Receiving a fast burst of HL7 messages no longer makes the Receive window stutter, and saving or sending a filtered file no longer briefly freezes the app.

improved A visual refresh across the entire app: consistent buttons and dialogs, a fully polished dark mode (calendars, progress bars, tooltips, and the update and license windows included), and clearer disabled states.

improved Better keyboard support: visible focus outlines when tabbing, Enter and Esc shortcuts in common dialogs, and Ctrl+Plus/Minus or Ctrl+Mouse Wheel zoom in the PDF and image viewers.

improved Embedded PDFs open instantly and show pages as they render instead of freezing on large documents; embedded documents now save with the correct file type (HTML, XML, and text are no longer always saved as RTF).

added Press Enter in the Remote Files browser to download the selected files or step into a folder; drag files onto the welcome screen to see a clear "Drop files to open" target.

v1.0.61 July 13, 2026

Paste Messages, Custom Columns & Fixes

added Paste an HL7 message straight into the current file — right-click the message list and choose "Paste message" to add a message without opening a new tab.

added Remote (SFTP) connections can now verify the server's host key and warn you if it changes, guarding against a silently intercepted connection.

improved Remove a custom field column by right-clicking its header or any of its cells.

improved Installing an update is more reliable — the app stays open if the installer can't start, offers to save unsaved changes first, and reopens the files you had open.
