Changelog

All notable changes to SIMple (the PWA and pysim-simple-server). The format follows Keep a Changelog; versions use MAJOR.MINOR.PATCH (see the README).

History before the first packaged release (v3.31.1) lives in the git log — every change carries a descriptive commit message.

[Unreleased]

[3.35.0] — 2026-10-23

Added

• EF.SMSP decoded editor — the full SMS-parameter form (TS 31.102 §4.2.27): alpha, TP-Destination Address and TS-Service Centre Address (each with its own length convention and a TON select; an empty SCA means the default SMSC), TP-PID, TP-DCS and the relative TP-VP — every parameter with an absent (the ME default applies) toggle. Live hints decode the DCS (TS 23.038 §4: coding group, alphabet, class, compression, message-waiting) and the relative validity period (TS 23.040 §9.2.3.12.1). Unchanged parameters keep their exact bytes (a card quirk such as a DCS marked absent with byte 00 survives), alphanumeric TON addresses are preserved read-only, and all checked records are validated before anything is written.

Fixed

• efDecSmsp mapped the parameter indicators shifted (SCA on bit 5, PID on bit 2, DCS on bit 3, VP on bit 4); the spec order is DA/SCA/PID/DCS/VP on bits 1–5 with bits 6–8 reserved — a record with a mixed indicator (e.g. E9) showed DCS and hid VP.
• The read-only EF.SMSP view decoded the TP-DA length as octets, although it is the digit count (TS 23.040 §9.1.2.5); a slot padded with 00 gained phantom digits.
• The Read decoded pill no longer looks disabled when it is enabled: an inactive-but- enabled pill is now an outlined button (blue on white/slate), and the grey fill and dimming are left to the actually disabled state.

[3.34.0] — 2026-10-23

Added

• Edit decoded, wave 2 — new editors for the service tables EF.UST / EF.IST / EF.EST (a filterable bit grid preserving services the table does not model), the scalars EF.ACC, EF.PHASE, EF.HPPLMN and EF.AD, the PLMN lists EF.PLMNsel / EF.FPLMN / EF.EHPLMN, the identities EF.ICCID / EF.IMSI (behind a confirmation — writing them changes the card identity) and the cell-broadcast lists EF.CBMI / EF.CBMID / EF.CBMIR. EF.SST is deliberately left read-only: its SIM layout is 2 bits per service (allocated + activated), which needs its own editor.
• The file-format survey (docs/decoded-editing.md) now records the shipped waves and marks EF.DIR / EF.ARR / EF.SMS / EF.PBR as postponed by decision (read-only).

Fixed

• EF.ACC class numbering (TS 31.102 4.2.15): byte 1 b8…b1 codes classes 15…8 and byte 2 classes 7…0 — the decoder counted class 0 at the MSB (an all-FF ACC read as class 0 instead of classes 0–15).
• EF.AD (TS 31.102 4.2.18): the operation mode is a whole-byte enum (00/80/01/81/02/04), not bits 0-1 plus a test bit; the MNC length may be 0 (service n°130 available) or absent (3-byte SIM form) — the editor previously refused both.
• EF.SST (TS 51.011 10.3.7): the SIM service table is decoded with its 2-bits-per- service layout (allocated + activated) instead of the UST 1-bit codec.
• EF.IMSI: the parity/type nibble is 9 for an odd digit count and 1 for an even one (TS 24.008 10.5.1.4); the encoder always wrote 9.
• Saving a PLMN/CB list with no edits no longer rewrites it as all-FF (the collected rows and the list encoders disagreed on the value shape).

[3.33.0] — 2026-10-23

Added

• Edit decoded in the file manager: a file is read raw, decoded into its own editable form, re-encoded in the browser and written through the normal update path. The first wave covers EF.SPN, EF.PLMNwAcT / EF.OPLMNwAcT / EF.HPLMNwAcT, the dialling-number files EF.ADN / EF.FDN / EF.SDN / EF.MSISDN / EF.LND / EF.BDN and EF.PNN. Shapes: a flat transparent form (SPN), a transparent list editor with add/remove rows (PLMN+ACT), per-record forms with a selection checkbox that is auto-checked when a field changes (dialling numbers, PNN) and per-record TLV item rows with add/remove/edit (PNN's full and short names plus the PLMN additional information). All checked records are encoded and validated before anything is written; unchanged fields, record lengths, extension pointers (EF.EXT1–EXT5), the BDN comparison-method byte and unknown PNN TLVs are preserved, and an edit that would break a reference (a number continued in an extension file, a dropped mandatory PNN full name) is refused.
• docs/decoded-editing.md: the file-format survey behind the design (every known EF classified by structure/coding into the editor's shapes S0–S10, with the release waves).

Removed

• The file manager's decoded view no longer carries the collapsed pySim JSON (server) disclosure — the view is the client-side EF decoder's table only. The disclosure was an unrelated second decode: opening it issued another /api/read with mode: 'decoded' to run pySim's read_binary_decoded/read_records_decoded, and it was reachable only when our decoder covered the file (Read decoded is decoder-gated), so the one case where a second opinion would matter — a file our decoders do not cover — never offered it. /api/read keeps mode: 'decoded' for API callers; the help, READMEs and project notes say the decoded table is built in the browser from the same raw bytes.

Fixed

• EF.BDN decodes and encodes with its own X+15 layout (the trailing Comparison Method Pointer); the shared ADN codec had treated it as X+14.
• efPlmnAct decoded the EC-GSM-IoT-only ACT (b8=1,b4=1,b3=0, 0x0088) as nothing while checking the impossible 0x0086 (TS 31.102 Table 4.2.5.2).
• PNN network names: the decoder now trusts a non-zero spare-bit count before the "all bytes < 0x80 → uncompressed" heuristic, so a valid packed name can no longer be misread (and later written back wrong).
• /api/write and /api/read report a cmd2 exception in the captured output as a failure instead of success: true with SW: 9000.
• The empty amber preset-mismatch banner no longer flashes on the SCP80/RAM view. ramOpChanged() (v3.28.0) un-hid #ram-preset-warning by the operation kind, but the banner's text and visibility belong to spPresetWarningRender() (which also handles the batch suppression): with no warning text the empty bordered box stayed visible until the next status poll re-hid it — on every RAM view and operation switch. The visibility is content-driven again; frontend/tests/ram.test.js pins it (the pre-fix code fails the test).

[3.32.5] — 2026-10-21

Fixed

• A card removed during the startup initialization no longer leaves the server reporting a phantom equipped card. The init caught the PC/SC error (and printed a traceback) but kept the card object it had already built, so card_present and _CARD_CONNECTED stayed True — and the auto-equip then skipped every later insertion (its _CARD_CONNECTED early return), leaving only a manual Equip or a restart. A PC/SC error now prints one line (INIT: card removed during initialization …), drops the half-initialized session and lets the presence monitor equip the next card.

[3.32.4] — 2026-10-21

Fixed

• The auto-equip's captured traceback now always includes the exception line: cmd2 renders a rich-box traceback longer than the logged head, so the actual error was cut off. The tail is appended after a ... marker; the "releasing the old link failed" message now says it continues with a fresh link (a removed card's dead PC/SC handle always fails to disconnect).
• A card insertion now marks the PC/SC link for a rebuild, so the first auto-equip attempt already uses a fresh link. On Windows the old link cannot connect after a swap — v3.32.2 recovered it, but only on the second attempt, after a failed init, a 2–4 s delay and a traceback in the log. A link created at a cardless startup has never connected either, which the same mark covers. The rebuild still runs in the equip worker (never in the pyscard monitor thread) and _ensure_transport releases the old link first.

[3.32.2] — 2026-10-21

Fixed

• The auto-equip loop after a card swap on Windows. A failed initialization with the card still present was reported as "card gone during initialization" and treated as a no-op success — so the three retries never ran and the watchdog re-armed every few seconds forever. It is a failure now, and every failed attempt marks the PC/SC transport for a rebuild, so the retry starts from a fresh link (the release of the old link happens first, so it cannot inherit a stale card handle). The error pySim swallowed is printed as AUTO-EQUIP: init output: with its traceback.

[3.32.1] — 2026-10-21

Added

• "Start counter value" in the outfile import: the counter every created keyset starts from. It defaults to the store's value (1); raise it for cards whose counters are already past it. The API takes start_counter (1–10 hex digits; a bad value is a 400), and the preview carries the value.

[3.32.0] — 2026-10-21

Added

• Updating a packaged install — update.sh / update.bat (and tools/update.py beneath them): downloads the latest release package, replaces the application files in place and re-installs the app into the existing .venv. pysim and its prerequisites (the slow part: pyscard builds from source on Linux) are kept, so an update takes seconds. --check reports the current and latest versions, --version picks a specific release, --zip updates from a local package (offline), --no-pip refreshes the files only, --force re-applies the same version.
• The release workflow now takes the release notes from this file's matching version section (falling back to generated notes when it is missing).

Changed

• Installs made from the v3.31.x packages have no updater yet: copy update.sh, update.bat and tools/update.py from this package once (or re-run setup from it). Later updates use update.sh / update.bat — or git pull for a clone.

[3.31.2] — 2026-10-20

Changed

• The SCP81 TLS-PSK listener states its Python requirement: it needs Python 3.13+ (ssl's PSK callbacks exist only since 3.13). Below that it raises a clear error instead of AttributeError, and the PSK tests are skipped (they run on 3.13+).
• The READMEs and the setup scripts: Windows strongly recommends Python 3.13 (pyscard has wheels up to 3.13; on 3.14 pyscard and some pysim dependency wheels are unavailable and build from source with MSVC).

[3.31.1] — 2026-10-20

The first packaged release (simple-3.31.1.zip).

Added

• EF_PBR (phonebook reference) support — the PBR is decoded in the decoded file views (the A8/A9/AA containers, the C0–CC kinds, the master EF), and the phonebook files it references (they are not in pySim's model) are added to the file tree server-side, selectable and readable.
• In-app dialogs — the native alert/confirm/prompt dialogs are replaced by a shared modal (queued, keyboard-aware, focus-trapped, ARIA-labelled).
• Windows console encoding guard — the start.bat PowerShell pipe can no longer kill the server on a character the ANSI code page lacks.
• GPL-2.0-or-later licensing (LICENSE, THIRD-PARTY-NOTICES), matching pysim.
• The curated release package (tools/build_release.py) and the tag-triggered .github/workflows/release.yml.

Changed

• setup.sh / setup.bat and the READMEs: on Linux pyscard builds from source and needs the PC/SC headers (libpcsclite-dev).
