+# Changelog
+
+## v0.6.6
+
+* replaced most signed integers with unsigned
+
+## v0.6.5
+
+* works on Python 3.10 and 3.11
+* fixed warnings about signed to unsigned comparison
+
+## v0.6.4
+
+* fixed a bug with slicing chunks in `VarlenSeries`
+* added extra comparison operators for `VarlenEntry`
+* added `sync` to `VarlenSeries`
+* fixed a bug with not propagating metadata write exceptions
+* fixed a bug with `Database` treating `varlen` and metadata as real time series
+
+
+## v0.6.3
+
+* added logging for opening and closing series
+
+## v0.6.2
+
+* added the context manager syntax to VarlenIterator
+* fixed a memory leak that happened during getting current value
+ from an empty series
+* added `MemoryPressureManager` support for `Database`
+
+## v0.6.1
+
+* fixed an issue with `Iterators`
+
+## v0.6
+
+* **bugfix**: fixed some bugs with reading values after close
+* added support for storing metadata as minijson
+ * this will be enabled by default is minijson is importable
+* fixed minor compiler warnings
+* `TimeSeries.iterate_range` will accept a parameter called
+ `direct_bytes` for compatibility with `VarlenSeries`.
+ It's value is ignored
+* more class constructors use explicit typing - faster tempsdb
+* `TimeSeries.get_current_value` will correctly raise `ValueError` instead of returning None
+
+## v0.5.4
+
+* older TempsDB databases that do not support varlens will be updated upon opening
+* added metadata support for databases
+* a flush will be done before re-enabling mmap
+* bugfix to read archive data
+
+## v0.5.3
+
+* added `disable_mmap`, `enable_mmap` and `open_chunks_mmap_size` into `VarlenSeries`
+
+## v0.5.2
+
+* added multiple properties and attributes to `VarlenSeries`
+
+## v0.5.1
+
+* added `VarlenSeries.close_chunks`
+* `Database.sync` will now return 0
+* indexed-gzip proved to be a poor choice, dropped
+* `setup.py` fixed
+
+## v0.5
+
+* if mmap is used, the kernel will be informed after loading the chunk that we
+ don't need it's memory right now
+* deleting a `TimeSeries` will now correctly return a zero
+* both `Database`, `TimeSeries` and `Chunk` destructor will close and
+ emit a warning if the user forgot to
+* if page_size is default, it won't be written as part of the metadata
+* added support for per-series metadata
+* following additions to `Database`:
+ * `delete_series`
+ * `delete_varlen_series`
+* following additions to `TimeSeries`:
+ * added `append_padded`
+ * added metadata support, `metadata` property and `set_metadata` call
+* added variable length series
+* added experimental support for gzipping time series
+* fixed a bug where getting a series that was already closed would TypeError
+* following additions to `Chunk`:
+ * `get_slice_of_piece_at`
+ * `get_slice_of_piece_starting_at`
+ * `get_byte_of_piece`
+ * `get_timestamp_at`
+* fixed the behaviour of `AlternativeMMaps` when passed a single index to __getitem__ and __setitem__
+* added `StillOpen` exception, chunk won't allow to close itself if it has any
+ remaining references
+
+## v0.4.4
+
+* more error conditions during mmap will be supported as well
+* ENOMEM will be correctly handled during resize operation
+* added `TimeSeries.descriptor_based_access`
+* added `Chunk.switch_to_mmap_based_access`
+
+## v0.4.3
+
+* improving handling mmap failures on too low memory
+* slightly reduced `metadata.txt` by defaulting `page_size`
+* moved `Chunk`
+* added support for gzipping
+* added `DirectChunk`
+* iterating and writing at the same time from multiple threads
+ made safe
+* added `TimeSeries.disable_mmap`
+* `Iterator`'s destructor will emit a warning if you forget to close it explicitly.
+* added option for transparent gzip compression
+ Please note that gzip disables mmap!
+* experimental gzip support for constant-length time series
+
+## v0.4.2
+
+* empty series will return an Iterator
+* **bugfix release** fixed `Database.create_series`
+* `Database` constructor will throw if no database is there
+* changed `Iterator.next` to `Iterator.next_item`,
+ synce Cython guys said to not implement the method `next`
+ on iterators.
+
+## v0.4.1
+
+* **bugfix release** fixed `get_open_series`
+
+## v0.4
