What changed on the site

2026.11.4 — the organisation's menu leads back to your captures and switches organisation; the list's Action sits above the list

Reports are as before: this release carries BacCat 0.9.111, as the last one did. On the site itself:

• The organisation's menu at the top of the page now has Captures too, so it leads back to the list from Projects, Archives and Data held, and it marks the page you are on.
• The capture list's Action has moved out of the filters into the bar above the list, just after the count of captures. The button for the ticked captures appears beside it, and nothing on the bar moves when you choose an action.
• Once you are signed in, "Get the app!" is a button beside "Upload a capture" rather than at the top of the page.
• If you belong to more than one organisation, you switch between them from the organisation's menu at the top of the page ("Switch to", at its foot) rather than from a separate box.

2026.10.63 — download BacCat Desktop from the site; signed updates for BacCat Desktop

Reports are as before: this release carries BacCat 0.9.111, as the last one did. On the site itself:

• BacCat Desktop can be downloaded from the site: "Get the app!" at the top of every page. Taking captures with it needs no account.
• The site now gives BacCat Desktop a second Strong Technology signature for each installer, which the Desktop checks before it updates itself.

2026.10.58 — act on many captures at once; the Terms' "What is whose"; copyright notices and a Notices page

This release carries BacCat 0.9.111, whose only change is the copyright and trademark notice at the foot of each report; the detail is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.111; the new report differs from the old one only at its foot. On the site itself:

• The list of captures can act on several at once: choose Archive, Restore, Rerun, Remove or Assign to project in the new Action box, and the list shows the captures that action applies to, with a box to tick beside each. Reruns wait while new uploads are analysed first.
• Every page's footer carries the copyright and trademark notices, and a link to a new Notices page, which lists the third-party software in BacCat Desktop and on this site, with each one's licence.
• The Terms of service have a new section, "What is whose": your captures remain yours; the reports made for your organisation you may keep, copy and share without limit; BacCat, BacCat Desktop and this website are licensed, not sold.

2026.10.56 — a 30-day trial; a Settings page, where the email about a finished capture can be turned off; Loytec captures

Reports are as before: this release carries BacCat 0.9.110, as the last one did. On the site itself:

• A new organisation's trial is 30 days, not 7. The Terms of service change with it: "Your organisation's first upload starts a free trial; the upload page says how long it lasts. The length is subject to change, but was 30 days as of this writing."
• A Settings page, the first entry in the menu under your name. On it you can turn off the email we send when a capture you uploaded or reran has been analysed; the email says where to find it.
• The Upload page says what to do with a capture from a Loytec router, which comes as a .zip: unzip it, name each capture file inside so you will recognise it, and upload each one.

2026.10.52 — BacCat 0.9.110; BacCat Desktop can check an update before it runs it

This release carries BacCat 0.9.110: on an MS/TP trunk, a device that sends frames with a broken network header is named, and a router's refusal names the device it refused; the detail is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.110 to get a report from it. On the site itself:

• BacCat Desktop is told the fingerprint (SHA-256) of each new installer, and a line on what changed, so that it can offer its own update and check the download before it runs it.

2026.10.49 — a 7-day trial for a new organisation; BacCat Desktop and the Devices page; email addresses confirmed by a code; BacCat 0.9.108, in about half the time

This release carries BacCat 0.9.108: damaged MS/TP frames that Wireshark misses are caught, names and values from long answers are shown, each device's firmware is listed, the Phoenix hoods section names the controllers' Who-Has fault, and a capture with an hour or more of nothing in it is analysed in parts; the detail is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.108 to get a report from it. On the site itself:

• A report is made in about half the time it took, and a small capture's in a few seconds.
• A new organisation no longer waits for review: its first upload starts a 7-day trial, and the front page and the upload page say so.
• A new account confirms its email address with a code from the email, typed on the page that asks for it, instead of a link. If you signed up before this release and have not confirmed your address, sign in: a code is sent.
• BacCat Desktop can create an account, sign in, send captures and fetch their reports. A Devices page, in your name's menu, lists the computers signed in with it and the version each runs, and signs one out.
• The Terms of service changed. "Access" says that an organisation's first upload starts a 7-day trial. "What we keep" says what we keep about each computer signed in with BacCat Desktop, until it is signed out, and, for a capture sent by BacCat Desktop, what it recorded about how the capture was taken; "Deleting your data" says that Delete erases that too.

2026.10.32 — BacCat 0.9.99

This release carries BacCat 0.9.99: corrupt MS/TP frames are counted as Wireshark shows them and each says what it shows, devices that transmitted while off the token ring and a device sending too fast are named, a trunk's baud rate is the one the capture states, devices stopping after a broadcast are reported only on a consistent pattern, poll periods are measured point by point, and three kinds of capture that made an analysis fail now get their report; the detail is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.99 to get a report from it. Nothing on the site itself changes.

2026.10.13 — BacCat 0.9.80

This release carries BacCat 0.9.80: the Phoenix hoods section shows the valve's flow reading beside the hood display's dropouts and each controller's firmware, long replies through a router are read as each device sent them, a router capture's tabs count their times from their own split-out file, a report saved from the browser keeps its tabs working in the saved file, and several findings are said more plainly; the detail is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.80 to get a report from it. Nothing on the site itself changes.

2026.09.55 — BacCat 0.9.67

This release carries BacCat 0.9.67: on an MS/TP trunk, three faults the report did not name before are each an error (a second token on the ring, a stretch of the bus the capture point cannot hear, the router off the trunk's ring), any dropout is an error, and several findings now say only what the capture shows; the detail is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.67 to get a report from it. Nothing on the site itself changes.

2026.09.50 — BacCat 0.9.62

This release carries BacCat 0.9.62: every point read or notified, listed by network and device with its name and what it reported, on the Polling and Change-of-value sections; the detail is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.62 to get a report from it. Nothing on the site itself changes.

2026.09.43 — BacCat 0.9.55; two small things on the site

This release carries BacCat 0.9.55; what is new in reports (a timeline of the discovery broadcasts on every tab, the capture length at the top of every LAN and trunk overview, a correction for routers on BACnet/Ethernet, and several findings reworded or made notes) is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.55 to get a report from it. On the site itself:

• On the Projects page the capture count reads "5 captures" and the whole phrase is the link.
• On a capture's page, while a new report is being made the "Open the report" button turns yellow, because until the new one is ready it opens the previous report; it turns blue again when the new report is in.

2026.09.38 — BacCat 0.9.50

This release carries BacCat 0.9.50 and changes nothing else on the site. What is new in reports (frames that arrived corrupt excluded and counted as their own finding, unanswered requests counted on short captures, a LAN overview opening every BACnet/IP and Ethernet tab, two new figures on every tab showing how each device's requests ended and the device numbers in use on each network, captures from an ARCNET network, and two corrections to MS/TP trunk reports) is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.50 to get a report from it; the first rerun of a capture after this release takes a little longer than usual, because BacCat reads the file again.

2026.09.31 — BacCat 0.9.43

This release carries BacCat 0.9.43 and changes nothing else on the site. What is new in reports (a Topology section on every tab, IP, Ethernet and MS/TP, saying what is on the link and where the capture was taken; the maker of each device's network card; a network number reached through two routers at once as an error; Who-Has in Discovery; folded long tables) is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.43 to get a report from it.

2026.09.25 — BacCat 0.9.37

This release carries BacCat 0.9.37 and changes nothing else on the site. What is new in reports (a tab per BACnet link on one wire and a tab for the router between them, readdressed devices called out up front, IP subnets without a BBMD between them called out as an error, COV objects on BACnet/Ethernet) is in BacCat's own notes. Every existing capture offers Rerun with BacCat 0.9.37 to get a report from it; a capture that carries two links gets its two tabs and split files on that rerun.

2026.09.22 — a tidier top bar, Rerun, and a captures list that reads more easily

This release tidies the top of every page and the captures list, from a review of the last one. It runs the same BacCat, 0.9.34, so your reports are unchanged, and the Terms are unchanged.

The top of every page.

• Your name opens a menu with your email address, Password and Sign out. They used to sit side by side across the top bar, which on a narrow window ran off the edge of the page; it no longer does.
• Your organisation's name opens a menu with its Projects, its Archives (the captures you have archived) and, for its administrators, Data held. These were links beside your plan above the captures list, and "Show archived" above the list; they are all here now.
• If your account belongs to more than one organisation, that menu is named for the one you chose in "Working in", and appears once you have chosen one. Changing "Working in" while you are on an organisation's Projects or Data held page shows that page for the organisation you changed to.
• The Strong Technology symbol sits beside BacCat, and there is a link to StrongTech.us, signed in or out; the company name at the foot of every page links there too.

Rerun.

• "Regenerate" is now called Rerun, everywhere on the site. On the captures list, a capture that a newer BacCat could analyse shows Rerun with newest BacCat on its own line under its version; it takes you to the capture's page, where the Rerun button is. While your organisation's plan has ended, that page says why there is no button.

The captures list.

• The list always has a Project column, with a dash for a capture in no project. The Project filter lists project names alone, and only the projects of the organisation you are working in.
• The filters are easier to read: the labels are bold and what is in the boxes is not, they fit on two rows, and the two upload dates always stay side by side.
• Clear is a button beside Filter, always there. It empties the filters and keeps the organisation you are working in.
• The line above the list names your plan, without links (they are in your organisation's menu).
• If your account belongs to more than one organisation, the notice that an organisation's plan has ended is shown while you work in that organisation, or in "All organisations"; not while you work in another one.

2026.09.15 — finding your captures: filters, projects, and working in one organisation

This release is about the captures list, for the day it has more on it than fits on a screen. It runs the same BacCat, 0.9.34, so your reports are unchanged. One sentence of the Terms has changed, to say that the name of the project you put a capture in is kept with it; the Terms are in the footer of every page.

Filters and pages.

• The captures list can be filtered: by name (words that appear in the file name or your description; * in a word stands for anything), by who uploaded, by status, by upload date, and to show only captures for which a newer BacCat is available. A filtered list is a web address you can bookmark or send to a colleague. Long lists are shown fifty at a time, newest first, with Newer and Older above and below the table.

Projects.

• A capture can be put in a project: a site, a building, a job. Choose one, or "New project…" and a name, when you upload, or on the capture's page afterwards. Projects belong to your organisation, so everyone in it sees the same list. The captures list has a Project column and a Project filter, and a capture's page links to the other captures in its project.
• An administrator of your organisation can archive a project that is finished with, from the organisation's projects page ("projects", beside your plan on the captures list): it leaves the drop-downs and its captures keep it. An archived project can be put back.
• On a capture's page the description is shown as text, with an Edit control, instead of always as a box to type in.

Working in one organisation. If your account belongs to more than one organisation, the top bar has a "Working in" choice. Pick one and the captures list shows only that organisation's captures, the plan line above the list is its, and the upload page opens on it, until you pick another or "All organisations". Choosing an organisation anywhere, in the list's filter or on the upload page, does the same at once. Accounts with one organisation see nothing new.

2026.09.8 — delete your data, what happens when a plan ends, a file for each link, and BacCat 0.9.34

This release is mostly about your data: what we hold, for how long, and your right to have it erased. The Terms have been rewritten to say all of it in plain words, and we ask you to read them; the link is in the footer of every page. It also brings BacCat 0.9.34, and with it downloadable per-link files for captures taken on a router.

Your data.

• You can delete a capture. On the capture's page, under Delete. It erases the capture, its reports, every file made from it, its file name and your description from our systems at once, and from our backups and any copy our engineers made within 30 days. It cannot be undone, by you or by us. The person who uploaded a capture, or an administrator of your organisation, can delete it; you may also ask us to.
• A page that says what we hold for your organisation, for its administrators: "data held", beside your plan on the captures list. It counts prepared captures, per-link files, any upload we kept because we could not read it, and captures you have removed from your view, because removing does not reduce what we hold. Delete everything is on the same page.
• What is left after a deletion is a line saying that a capture was uploaded and deleted, with measurements of it and a fingerprint of each erased file, and nothing that names you or your devices. The Delete page and the Terms list it exactly.
• Archive and Remove are for tidying, and delete nothing. Anyone in your organisation can archive a capture to take it out of the list (its links keep working, and "Show archived" brings it back). The person who uploaded it, or an administrator, can remove it from your organisation's view for good. Old reports of a capture can be removed; the newest always stays.

When a plan ends.

• Your captures stay readable for the plan's grace period (90 days on the free beta). Everyone in your organisation can still open, download, archive, remove and delete captures and reports; uploading, new reports and editing descriptions are switched off, and each page says until when.
• After that date the captures can no longer be opened, and we make no commitment to keep them: download anything you need before the date shown. An administrator can still see what we hold, and delete it.

Captures and reports.

• This release carries BacCat 0.9.34 (what changed in reports is in BacCat's notes). Because the site now runs a newer BacCat than the one that made your existing reports, every capture offers Regenerate. It does not count against the day's uploads, and the earlier report stays available.
• A capture with several links (a router's own capture, with its MS/TP ports and its LAN) now keeps one file per link, downloadable from the capture's page singly or as a zip. Each tab of the report names the file its frame numbers refer to. An older multi-link capture gets its files the first time you regenerate its report.
• We can upload a capture for you. If a capture is over your plan's size, or you have used the day's uploads, Strong Technology staff can upload it to your organisation on request. It appears in your list like any other, marked as uploaded by staff, and you can regenerate its report yourself later.
• When a capture cannot be analysed, its page now says what we kept and why: nothing, if the file was rejected; the prepared copy, if its analysis failed; the file as you uploaded it, for Strong Technology staff only and for 30 days (90 at most), if it could not be prepared at all. We are now told when an analysis fails, and can try the capture again once BacCat has been fixed. If that works you get an email and the report appears on the capture's page as for any other.

Smaller things.

• Release notes are on the site: the site number in the footer links to this page, and "What changed?" beside a newer BacCat version links to what changed in reports.
• Fixed: a description typed while a capture was still being analysed was lost when the analysis finished.

2026.09.1 — a capture can have more than one report

The site now keeps a capture and its reports as separate things, so that a report can be made again when BacCat improves, without uploading anything. BacCat itself is unchanged in this release (still 0.9.33): the reports are the same. The site has its own release number from now on, in the footer of every page; the BacCat version in a report's header still tells you which analysis produced that report.

Regenerate a report.

• When a newer BacCat is running than the one that made a capture's report, the capture's page says so ("Generated with BacCat 0.9.33; current is 0.9.34") and offers Regenerate: a new report from the prepared capture we already hold. The list of captures marks them "newer available".
• It does not count against the day's analyses. Anyone in your organisation can ask for it, and whoever asked gets the email.
• The earlier report stays available from the capture's page, under "Reports of this capture". Links already sent by email open the newest.
• You will first see this when the next BacCat version is released.

What was kept, per capture.

• The capture's page now states what was kept from that upload: which BacCat prepared it, any non-standard UDP ports that were read as BACnet/IP or LON/IP, and the exact filter that was applied. It stays true of that file even when a later version keeps something different.

Smaller things.

• A capture can be given a description, and it can be edited later.
• The upload page shows how many of the day's analyses have been used.
• An analysis interrupted by maintenance now restarts by itself. Before, it could sit at "Analysing" indefinitely.
