2026.09.30 - version 3.6.30

• New: an option that leaves every product, variation and category that already carries a Linet id out of a WC->Linet run, so a run sends only what has never been pushed. A catalogue that has been pushed once is mostly items Linet already knows, and each of them still cost the run a lookup and an update. Off by default, and a product pushed by hand or on save still goes up whatever its id says
• New: a picture over 2 MB goes up as the largest of the sizes WordPress made for it that fits under the limit, rather than as the original. The file is sent base64 encoded inside the create/file body, half as long again for being encoded, which is what turned one heavy picture into a request Linet refused or never answered. A picture with no version small enough is left out and said so in the log. The limit can be changed, or turned off, with the woocommerce_linet_pic_max_bytes filter
• New: the J5 fields of a document carry the card token and the approval number of the hold for PayPlus orders, which is what a held J5 is charged against - the same pair a zcredit order already sent. An order with no token sends the transaction uid as before
• Updated: the picture itself is left out of the log. One create/file wrote the whole file into the debug log, base64 and all, so a run over a catalogue of pictures wrote a log of mostly pictures; the line now says how big the file was instead
• Updated: the plugin asks for php 7.4 rather than 8.0. Nothing in it needs 8.0 - the newest thing the code uses is from 7.0 - and WooCommerce itself asks for no more than 7.4, so the higher number was only keeping the plugin off sites it runs on perfectly well, and off the update WordPress would otherwise offer them. Tested against php 8.4, WordPress 7.0 and WooCommerce 10.9
• Fix: a call that died mid request - an empty reply, a connection reset, a refused connection, a name that will not resolve - counts as Linet not answering, the same as a call that ran out of time already did. A create/file that Linet fell over on read as an ordinary failure, so the run went on to ask the same dead server once per product for the rest of the catalogue

2026.09.21 - version 3.6.29

• New: three calls in a row that never come back stop the run and say so, instead of walking the rest of the catalogue a timeout at a time. When Linet stopped answering, one product could spend a minute and a half on three calls that were never going to arrive, and the run went on knocking for as long as the page was open. Calls that time out now and again, with answers in between, are not enough to stop anything
• New: a call that goes unanswered holds every process back before the next one is sent - ten seconds, then twenty, then thirty - the same as a refusal for going over the rate limit already does. A call that never came back is the plainest word Linet has for "not now", and the plugin was answering it by asking again straight away
• New: the hold lets go by itself once its wait is up, and the next call through decides whether Linet is back. A sync that gave up in the afternoon can never leave an order that evening with its document refused unasked
• Updated: every item and file lookup now goes through newsearch, which is where Linet documents filtering, rather than search/item and search/file. A lookup by sku or by Linet id asks for a single row, because that is all there is to find; the count of items in a category still reads the category, because a row count is the answer it is after
• Updated: asking whether a picture is already on an item asks for a single row, and reading an item's gallery asks for at most 50 files, instead of reading every file the item has gathered. The number can be changed with the woocommerce_linet_gallery_limit filter
• Fix: a picture is created when the answer carries no rows as well as when Linet says so with errorCode 1000, so a picture that is not in Linet yet is still sent whichever way the answer is worded A sku is unique in Linet's items table, so one row is all there is to find, and this is the call the sync makes most - once per product on a push, and again for every line of a document when items are matched by sku
• Fix: a document whose sku lookup went unanswered no longer stops with a php error from reading the answer that never came
• Fix: the check for whether the Linet id noted on a product is still there now reads an empty answer as "not there" as well as the not-found reply search/item sends, so an id that points at a deleted item is let go of rather than updated. A lookup that went unanswered is neither, and is left alone as before
• Updated: a call is given 15 seconds to answer rather than 30. A healthy call comes back in well under a second, so thirty was a long time to hold a php process open for an answer that was not coming

2026.09.21 - version 3.6.28

• Fix: a sync pulse that has not come back is now given up on after five minutes rather than one, and is asked for again at most three times before the run is stopped. A minute was under what a pulse honestly takes once Linet starts holding calls back, so the page was dropping pulses that were still working and asking for the same products over again - and the pulse it dropped carried on talking to Linet at the site's end. The count of retries was already being kept, but nothing was reading it, so this could go on for as long as the page was left open
• Fix: only one pulse of a Linet->WooCommerce pull runs at a time. The pull had no lock of its own, so every pulse the page gave up on left another reader behind it, and the number of them talking to Linet at once grew for as long as the sync was left running. The category half of a push is under the same lock as the items
• Fix: a pulse turned away because an earlier one is still running now waits longer each time instead of asking every five seconds for ever, and gives up after twenty tries
• Fix: a pull whose call to Linet went unanswered - a network error, a rate limit that outlived its retries, or an error page where the answer was meant to be - now stops the run and says so. An answer that was not there reads exactly like an answer with nothing left in it, so the sync was ending early and reporting that it had finished

2026.09.21 - version 3.6.27

• New: a variation is placed in its Linet matrix by the ruler unit it sits on, sent on the item itself, instead of by numbers packed into its SKU, and goes up as a matrix cell (item type 4). A variation that went up under the old numbered SKU is found and renamed rather than created a second time beside itself
• New: a variation keeps its own SKU in Linet, and one that has no SKU of its own is given one rather than taking the parent's. A variable product's SKU is no longer rewritten in WooCommerce to take the dashes out of it
• New: a variable product can carry more than two attributes in both directions
• Fix: a variable product coming back from Linet with more than one ruler now carries an attribute for each of them; every ruler after the first was writing over the one before it, leaving the product with a single attribute
• Fix: a ruler that could not be mapped no longer takes up an axis of the matrix, which was leaving a gap in the order the rulers sit in
• Fix: the code a ruler unit is filed under in Linet is sent in Code 39, which is all Linet accepts there. A Hebrew attribute value was refused outright ("Only Code39 characters are allowed") and the unit was never created, so no variation could be placed on its ruler. The unit's name and slug are unchanged, so it still reads as the word itself in Linet; only the code falls back, to the WooCommerce term ID
• Fix: a variation whose parent product has not reached Linet yet sends a parent item of 0 rather than an empty value

2026.09.20 - version 3.6.26

• Fix: pushing a product whose SKU is already on a Linet item no longer ends the push with a database error from Linet ("Duplicate entry ... for key 'sku'"); the existing item is found and updated instead, including an item that was switched off in Linet, which is looked up with newsearch/item and active 0 and comes back on as part of the update
• Fix: only one pulse of a WooCommerce to Linet push runs at a time, so a pulse that is slow because of Linet's rate limit and gets asked again by the page can no longer create the same item twice
• Fix: a product is no longer created in Linet when the search for its SKU went unanswered (timeout, or the rate limit ran out); it is left for the next run
• Fix: stripping the dashes out of a variable product's SKU is skipped when another product already uses the stripped SKU, instead of stopping the push with a WooCommerce error
• New: the Maintenance tab lists how many products and categories carry a Linet ID and clears the lot with one button, for IDs that point at items from somewhere other than the connected company. Nothing is deleted in WooCommerce or in Linet, only the link, and the next sync maps everything again, items by SKU and categories by name

2026.09.18 - version 3.6.25

• Fix: 3.6.24 was released without the rate limiter and sync cache classes, causing "Class not found" errors on API calls, the settings page and inventory sync

2026.09.17 - version 3.6.24

• Fix: account name, phone, address and city are cut to the lengths Linet accepts before the account is created or updated, so a long company name or phone no longer makes Linet reject the account (also for accounts created from Elementor and Contact Form 7 forms)
• Fix: document company, address, city, phone and the billing and shipping address fields are cut to Linet's limits, so a long value no longer stops the document from being created
• Fix: document line names (products, variations, coupons, shipping and fees) are cut to 255 characters, and a line with an empty name is sent as "Item" instead of being rejected by Linet

2026.08.25 - version 3.6.23

• Fix: the per-product sync actions now check the admin nonce, so a third-party page can no longer drive a logged-in administrator's browser into syncing a product
• Updated: when Sync Items is set to Off, the "Sync Item From Linet" button is hidden and the request is refused, instead of pulling from Linet anyway

2026.08.19 - version 3.6.22

• New: the Maintenance tab now lists every product behind a problem, each one linked to its WooCommerce edit screen and to the shop
• New: duplicate rows show which product is kept and which are the duplicates, with a delete link per product next to the "delete all duplicates" button
• New: a duplicate Linet ID can now be cleared from the extra products instead of deleting them
• New: images without sizes list the products that use them, and the rebuild action now uses the file WordPress has on record
• New: maintenance actions ask for confirmation and report what happened, instead of silently hiding the row
• Fix: duplicate detection ignores empty SKUs, trashed products and postmeta rows left behind by deleted posts, so the tab no longer reports duplicates that do not exist
• Fix: duplicate variations are matched on their real attribute values rather than on the attribute summary text
• Fix: clearing a duplicate Linet ID no longer removes it from the product that keeps it
• Fix: a failed search/file or create/file call during WC->Linet sync no longer crashes with "Attempt to assign property body on null" - the image is skipped, logged, and the sync batch carries on
• Fix: the log no longer shows percent-encoded slugs - "%d7%9e%d7%99%d7%93%d7%94" is written as the Hebrew it stands for, while a %20 inside a logged url is left alone
• Fix: requests and answers are logged as readable text instead of \u05de escapes
• Fix: downloading a log file returns it as it was written, instead of html-escaping every quote to "
• Fix: maintenance actions now require the manage_woocommerce capability
• Updated: each section lists at most 100 groups and says so, instead of building an unbounded page

2026.08.16 - version 3.6.21

• New: WC->Linet sync now pushes all product categories in a first phase, before any item is synced
• New: category hierarchy is now sent to Linet - parent_id set from the parent term's Linet category id
• Fix: a category already mapped to Linet is now updated on sync, instead of only being checked for existence
• Fix: Linet->WC categories are now synced parents first, so a child no longer lands at top level when it arrives before its parent
• Fix: a category moved to top level in Linet is now flattened in WooCommerce as well
• Updated: WC->Linet item sync no longer re-resolves categories through the API for every product

2026.06.25 - version 3.6.20

• Upgrade: new paypal gateway support

2026.06.25 - version 3.6.19
